Suppose you have a circuit you are working with, but you recognize that there is a really strong LaTeX: 60\text{Hz}60 Hz hum due to the AC power being provided to your system. You wish to reduce the effect of this humming but not any other frequency content in the signal. Which type of filter should you use to remove it

Answers

Answer 1

Answer:

A bandstop filter should be used to remove the 60 Hz humming component of the signal.

A bandstop filter basically allows all the frequencies above and below a specific frequency that is 60 Hz in this case.

Therefore, only the 60 Hz component of the signal will be attenuated and the rest of the frequency components in the signal will not be affected.

Explanation:

There is a really strong 60 Hz hum (noise) due to the AC power being provided to your system.

We wish to reduce the effect of this humming but not any other frequency content in the signal.

So we need a filter that can reject a particular frequency but allow any other frequencies present in the signal.

A bandstop filter would get the job done.

A bandstop filter basically allows all the frequencies above and below the specific frequency that is 60 Hz in this case.

Therefore, only the 60 Hz component of the signal will be attenuated and the rest of the frequency components in the signal will not be affected.

The notch frequency in this case is 60 Hz which is the frequency at which maximum attenuation occurs.

The typical frequency response of a bandstop filter is attached below.

A parallel helical gearset consists of a 19-tooth pinion driving a 57-tooth gear. The pinion has a left-hand helix angle of 30°, a normal pressure angle of 20°, and a normal module of 2.5 mm.
Find:_______.
(a) The normal, transverse, and axial circular pitches
(b) The transverse diametral pitch and the transverse pressure angle
(c) The addendum, dedendum, and pitch diameter of each gear

Answers

Answer:

a)

normal circular pitch = 7.8539 mm

transverse circular pitch = 9.0689 mm

axial circular pitches = 15.7077

b)

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle is 22.8°

c)

Addendum = 2.5 mm

dedendum = 3.125 mm

pinion diameter = 54.8482 mm and Gear diameter = 164.5448 mm

Explanation:

Given that;

module m = 2.5 mm

Number of teeth on Gear  nG = 57 TEETH

Number of teeth on Pinion  nP = 19 TEETH

Helix angle W = 30°

Normal Pressure angle β = 20°

finding the circular pitch

Pc = πm

we substitute

Pc = π * 2.5 mm = 7.8539 mm

now the diametral pitch p = π / Pc

= π / 7.8539

= 0.4 teeth/mm

a)

So the normal circular pitch

Pn = π / P

Pn = π / 0.4

Pn = 7.8539 mm

the transverse circular pitch

Pt = Pn / cosW

Pt = 7.8539 / cos30°

Pt = 9.0689 mm

for axial circular pitches

Px = Pt / tanW

Px = 9.0689 / tan30°

Px = 15.7077

b)

The transverse diametral pitch and the transverse pressure angle.

The transverse diametral pitch Pt = PcosW

= 0.4 * cos30°

= 0.3464 teeth/mm

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle  β1 = tan^-1 ( tan βn / cos W)

=  tan^-1 ( tan20° / cos 30°)

= tan^-1 ( 0.42027 )

β1 = 22.8°

transverse pressure angle is 22.8°

c)

The addendum, dedendum, and pitch diameter of each gear

Now from table standard Tooth proportions for Helical Gears;

Addendum a = 1/p

= 1 / 0.4

= 2.5 mm

dedendum b = 1.25 / p

= 1.25 / 0.4

= 3.125 mm

now  pinion diameter dP = Np / PcosW

= 19 / 0.4 (cos30°)

= 54.8482 mm

Gear diameter dG = nG / pcosW

= 57 / 0.4 (cos30°)

= 164.5448 mm

Assume you wish to transfer an n B file along a path composed of the source, destination, 7 point-to-point links, and 5 switches. Suppose each link has a propagation delay of 2ms and a bandwidth of 4Mbps, and that the switches support both circuit and packet switching. Thus, you can either break the file up into 1-KB packets or set up a circuit through the switches and send the file as one contiguous bitstream. Suppose that packets have 24B of packet header information and 1000B of payload, store-and-forward packet processing at each switch incurs a 1-ms delay after the packet had been completely received, packets may be sent continuously without waiting for acknowledgments, and circuit setup requires a 1-KB message to make one round trip on the path, incurring a 1-ms delay at each switch after the message has been completely received. Assume switches introduce no delay to data traversing a circuit. You may also assume that filesize is a multiple of 1000B.A. For what filesize n B is the total number of bytes sent across the network less for circuits than for packets?
B. For what filesize n B is the total latency incurred before the entire file arrives at the destination less for circuits than for packets?C. How sensitive are these results to the number of switches along the path? To the bandwidth of the links? To the ratio of packet size to packet header size?D. How accurate do you think this model of the relative merits of circuits and packets is? Does it ignore important considerations that discredit one or the other approach? If so, what are they?

Answers

Answer:

a) n > 8600 bytes

b) 9500 bytes

c) The results calculated above a very sensitive to the ratio of the packet size to the packet header

d) the model is accurate because N > 9500 bytes

Explanation:

A) The filesize n B

no of bytes transferred = no of packets * packet size

                                      = ( n / 1000 ) * 1024

circuit switching

number of bytes transferred = file size + two packets

                                               = n + (2 * 1024)

comparing both equations

= n + (2048)  <  ( n/1000) * 1024

=  24 * n / 1000 > 2048

hence: n > 8600 bytes

B )  The filesize n B is the total latency incurred before the entire file arrives at the destination less for circuits than for packets

packet switching :

Latency = ( n/1000 ) * ( 1024 * 8 bits/4 Mbps ) + 3 * ( 1024 * 8 bits / 4 Mbps) s + (3 * 1 ms + 4 * 2 ms)

=  ( n * 2 * 1026 / 10^6 )ms + 6.144 + 11

Circuit switching

Latency = ( n * 8 bits/ 4 Mbps ) s + 4 * 2 ms + 2 * ( 4 * 1024 * 8/4 mbps + 3 * 1 ms + 4 * 2 ms )

= n * 2*10 n3 / 10^6 ms + 8 + 2 * ( 19.1920 )

= 2n / 10 n3 + 38.3840

therefore for n to meet the requirement

( n * 2 * 1024 / 10 n6 ) ms + 17.144 > 2n / 10 n3 + 38.384

hence N > 9500 BYTES

C ) The results calculated above a very sensitive to the ratio of the packet size to the packet header

D) The model is accurate because N > 9500 bytes

for internal cooling, air cooled engines are especially dependent on

A. the circulation of lubricating oil.
B. air flowing over the exhaust manifold.
C. a properly functioning thermostat.

Answers

For internal cooling, air-cooled engines are especially dependent on B. air flowing over the exhaust manifold.

Air-cooled engines rely on the circulation of air to dissipate heat and maintain optimal operating temperatures. Unlike liquid-cooled engines that utilize a coolant system with a radiator, air-cooled engines do not have a separate cooling medium. Instead, they rely on the natural flow of air to cool the engine components, including the cylinder heads and cylinders.

Among the options provided, air flowing over the exhaust manifold plays a critical role in cooling air-cooled engines. The exhaust manifold is a component that collects and directs the hot exhaust gases away from the engine cylinders. As these hot gases exit the cylinders and pass through the exhaust manifold, they carry a significant amount of heat with them.

When air flows over the exhaust manifold, it assists in transferring the heat from the manifold to the surrounding environment. This process helps in cooling the manifold itself, which in turn aids in cooling the adjacent engine components. The continuous flow of air ensures that the heat generated by the combustion process is effectively dissipated.

While the other options mentioned, such as the circulation of lubricating oil (A) and a properly functioning thermostat (C), are important for the overall operation and performance of an engine, they are not specifically related to the cooling mechanism in air-cooled engines.

In summary, among the options provided, air flowing over the exhaust manifold is especially crucial for the internal cooling of air-cooled engines. This airflow assists in dissipating heat and maintaining optimal operating temperatures, contributing to the overall cooling effectiveness of the engine.

A retaining walL with a smooth vertical bar retains a soil mass having a horizontal surface to depth of 5.4 meters . calculate the magnitude of the resultant active thrust on the wall and give its line of action . the soil has an angle of shearing resistance of 30 and unit weight of 19.8KN per cubic meter

Answers

Note that the magnitude of the resultant active thrust on the wall is 876.69 kN.

What is the explanation for the above response?


To calculate the magnitude of the resultant active thrust on the wall, we need to use Rankine's theory of earth pressure.

Let's assume that the wall height is also 5.4 meters, and the angle of wall friction is zero.

Then, the total active thrust (Q) is given by:

Q = Ka * H * gamma * H/2

Where,

Ka = Active earth pressure coefficient

H = height of the wall

gamma = unit weight of soil

The active earth pressure coefficient can be calculated using the following formula:

Ka = (1 - sin(phi)) / (1 + sin(phi))

Where, phi = angle of shearing resistance of soil

Substituting the given values, we get:

phi = 30 degrees

H = 5.4 meters

gamma = 19.8 kN/m^3

Ka = (1 - sin(30)) / (1 + sin(30)) = 1/3

Q = Ka * H * gamma * H/2 = (1/3) * 5.4 * 19.8 * 5.4/2 = 876.69 kN

Therefore, the magnitude of the resultant active thrust on the wall is 876.69 kN.

The line of action of the resultant active thrust on the wall will be at one-third of the height of the wall from the bottom. Therefore, the line of action of the active thrust will be at a height of 1.8 meters from the bottom of the wall.

Saturated refrigerant-134a vapor at 15 psia is compressed reversibly in an adiabatic compressor to 80 psia. Determine the work input to the compressor. Use the tables for R-134a.

Answers

The initial enthalpy and the entropy of the saturated water can be found out from the table of A-12E

i.e.   \($h_1= 101 \ \text{Btu/lbm}$\)

       \($s_1 = 0.22717 \text{ Btu/lbmR}$\)

Since the process mentioned above is an adiabatic compression process, the entropy will remain constant throughout the process. Therefore, we take the value of entropy and the final pressure using the table with few interpolations and also approximations to find the final enthalpy. It is given by :

       \($h_2= 116.09 \text{ Btu/lbm}$\)

So the work input from the energy balance equation :

       \($\dot{W} + \dot{m}h_1 = \dot{m}h_2$\)

          \($w=h_2 - h_1$\)

              = 116.09 - 101

Question 38

What would be the demand load for this branch circuit for the loads 4, 5, and 6? (Show all of your calculations in your word-processing document.) (5 points)

Answers

To calculate the demand load for each branch circuit, we need to first determine the individual loads of each item and then apply demand factors as per the National Electrical Code (NEC).

For question 37, we need to add up the individual loads of items 1, 2, and 3.
Item 1: A continuous load of 12 amps
Item 2: A non-continuous load of 20 amps
Item 3: A non-continuous load of 10 amps
Therefore, the total load for the branch circuit would be:
12A + 20A + 10A = 42A

Once you have the load values for loads 1, 2, and 3, you can simply add them together to find the total demand load for the branch circuit. For example, if load 1 is 10A, load 2 is 15A, and load 3 is 20A, the demand load for the branch circuit would be 10A + 15A + 20A = 45A.

The acceleration of a particle is defined by the relation a = 9 − 3t2, where a and t are expressed in ft/s2 and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 5 ft. Determine (a) the time when the velocity is again zero, (b) the position and velocity when t = 4 s, (c) the total distance travelled by the particle from t = 0 to t = 4 s.

Answers

(a) To find the time when the velocity is again zero, we set the velocity equal to 0 and solve for t:

0 = v0 + at = 9t - 3t^3

Solving for t, we find that t = ±1.

(b) To find the position and velocity when t = 4 s, we first need to find the velocity equation by integrating the acceleration equation:

v = ∫a = ∫(9 - 3t^2)dt = 9t - t^3 + C

Using the initial condition v(0) = 0, we find C = 0 and

v(t) = 9t - t^3

Next, we integrate v(t) to find the position equation:

x = ∫v = ∫(9t - t^3)dt = 3t^2 - t^4 + C

Using the initial condition x(0) = 5, we find C = 5 and

x(t) = 3t^2 - t^4 + 5

Evaluating x(t) and v(t) at t = 4 s, we have:

x(4) = 3(4^2) - 4^4 + 5 = 51

v(4) = 9(4) - 4^3 = -36

(c) To find the total distance travelled by the particle from t = 0 to t = 4 s, we need to find the distance between the initial and final positions:

d = x(4) - x(0) = 51 - 5 = 46 ft

So the total distance travelled by the particle from t = 0 to t = 4 s is 46 ft.

The maximum stresses of the section near the fixed end are Bending stress, -10.16 ksi and Shear stress, 1.89 ksi.

How to calculate critical stresses?

To determine the maximum stresses at a section near the fixed end of the beam, calculate the bending stress and the shear stress.

First, let's find the reactions at the fixed end of the beam. Since the beam is completely fixed, the reactions will be equal and opposite to the applied force, which means:

Rx = -Fx = -400 lb

Ry = -Fy = 300 lb

Rz = -Fz = 1200 lb

Next, calculate the bending moment caused by the applied force. Since the force passes through the centroid of the beam, we can assume that the moment arm is equal to half the depth of the beam, which is 4.055 inches. Therefore, the bending moment at the section near the fixed end is:

M = Fz × 4.055 in = -4875 lb·in

Using the moment of inertia about the x-axis (centroidal-longitudinal axis), calculate the bending stress:

σx = M × (H/2) / Ix = -10.16 ksi

Next, calculate the shear stress using the shear force caused by the applied force. Since there is no other load on the beam, the shear force at the section near the fixed end is equal to the reaction force in the y-direction, which is 300 lb. Using the area of the web, calculate the shear stress:

τ = V × (W × t) / (2 × Iy) = 1.89 ksi

where V is the shear force, W is the width of the web, t is the thickness of the web, and Iy is the moment of inertia about the y-axis (centroidal-vertical axis). Note that we assume the shear stress distribution is uniform across the thickness of the web.

Therefore, the maximum stresses at the section near the fixed end of the beam are:

Bending stress: σx = -10.16 ksi

Shear stress: τ = 1.89 ksi

The bending stress is compressive and larger in magnitude than the yield stress of the material, which means the beam will fail due to bending. The shear stress is relatively small and does not contribute significantly to the failure of the beam.

When mechanical work is done on a system, an increase normally occurs in its
O temperature.
O internal energy.
O both of these
O neither of these

Answers

An rise in temperature and internal energy often happens when a system is subjected to mechanical action.

It is impossible to directly quantify the internal energy of systems that are more complicated than a perfect gas. The system's internal energy is still inversely related to its temperature, though. Therefore, by keeping an eye on how the system's temperature varies, we can track changes in the system's internal energy. We may infer that the system's internal energy has grown whenever the system's temperature rises.

For the time being, let's assume that a thermometer set in a beaker of water on a hot plate registers 73.5°C, as indicated in the diagram below. Only the system's condition at that precise instant may be described by this measurement.

Statement and decision testing exercise
Scenario: A vending machine dispenses either hot or cold drinks. If you choose a hot drink (e.g. tea or coffee), it asks if you want milk (and adds milk if required), then it asks if you want sugar (and adds sugar if required), then your drink is dispensed.

a. Draw a control flow diagram for this example. (Hint: regard the selection of the type of drink as one statement.)

b. Given the following tests, what is the statement coverage achieved? What is the decision coverage achieved? Test 1: Cold drink Test 2: Hot drink with milk and sugar

c. What additional tests would be needed to achieve 100% statement coverage? What additional tests would be needed to achieve 100% decision coverage?

Answers

To achieve 100% statement coverage, additional tests are needed to cover different combinations of drink preferences (milk and sugar). For 100% decision coverage, tests should cover both the selection of drink type and the decisions related to adding milk and sugar.

-Why is it said that using faulty PPE could be just as dangerous as using no PPE at all?

Answers

Answer:

Explanation:

"Safety helmet" redirects here. It is not to be confused with hard hat.

Drug Enforcement Administration (DEA) agents wearing Level B hazmat suits

Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. "Protective clothing" is applied to traditional categories of clothing, and "protective gear" applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit.

The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it does not eliminate the hazard at the source and may result in employees being exposed to the hazard if the equipment fails.[1]

Any item of PPE imposes a barrier between the wearer/user and the working environment. This can create additional strains on the wearer; impair their ability to carry out their work and create significant levels of discomfort. Any of these can discourage wearers from using PPE correctly, therefore placing them at risk of injury, ill-health or, under extreme circumstances, death. Good ergonomic design can help to minimise these barriers and can therefore help to ensure safe and healthy working conditions through the correct use of PPE.

Practices of occupational safety and health can use hazard controls and interventions to mitigate workplace hazards, which pose a threat to the safety and quality of life of workers. The hierarchy of hazard controls provides a policy framework which ranks the types of hazard controls in terms of absolute risk reduction. At the top of the hierarchy are elimination and substitution, which remove the hazard entirely or replace the hazard with a safer alternative. If elimination or substitution measures cannot apply, engineering controls and administrative controls, which seek to design safer mechanisms and coach safer human behavior, are implemented. Personal protective equipment ranks last on the hierarchy of controls, as the workers are regularly exposed to the hazard, with a barrier of protection. The hierarchy of controls is important in acknowledging that, while personal protective equipment has tremendous utility, it is not the desired mechanism of control in terms of worker safety.rly PPE such as body armor, boots and gloves focused on protecting the wearer's body from physical injury. The plague doctors of sixteenth-century Europe also wore protective uniforms consisting of a full-length gown, helmet, glass eye coverings, gloves and boots (see Plague doctor costume) to prevent contagion when dealing with plague victims. These were made of thick material which was then covered in wax to make it water-resistant. A mask with a beak-like structure which was filled with pleasant-smelling flowers, herbs and spices to prevent the spread of miasma, the prescientific belief of bad smells which spread disease through the air.[2] In more recent years, scientific personal protective equipment is generally believed to have begun with the cloth facemasks promoted by Wu Lien-teh in the 1910–11 Manchurian pneumonic plague outbreak, although many Western medics doubted the efficacy of facemasks in preventing the spread of disease.[3]

Types

Personal protective equipment can be categorized by the area of the body protected, by the types of hazard, and by the type of garment or accessory. A single item, for example boots, may provide multiple forms of protection: a steel toe cap and steel insoles for protection of the feet from crushing or puncture injuries, impervious rubber and lining for protection from water and chemicals, high reflectivity and heat resistance for protection from radiant heat, and high electrical resistivity for protection from electric shock. The protective attributes of each piece of equipment must be compared with the hazards expected to be found in the workplace. More breathable types of personal protective equipment may not lead to more contamination but do result in greater user satisfaction.[4]

The use of a faulty PPE could be just as dangerous as not using any PPE at all because the user is still exposed to potential hazards and harm.

What is PPE?

PPE is an acronym for personal protective equipment and it can be defined as a terminology that is used to denote any piece of equipment which offer protection to different parts of the body while working in a potentially hazardous environment.

Some examples of personal protective equipment (PPE) used to protect the different parts of the body are:

RespiratorsFace maskFace shieldGlovesBootsHelmet

According to OSHA, the use of a faulty PPE could be just as dangerous as not using any PPE at all because the user is offered little or no protection at all.

What is data definitions?

Data definitions, also known as data declarations or variable declarations, are statements in a programming language that define the type and name of a variable or data object. These declarations allocate memory space for storing data and specify how the data will be interpreted and used.

In programming, data definitions are essential for explicitly declaring variables before using them in a program. They provide information about the type of data the variable will hold (e.g., integer, string, array) and allocate memory accordingly.

Data definitions can include various types of data, such as integers, floating-point numbers, characters, strings, arrays, structures, and more. The specific syntax and rules for declaring data depend on the programming language being used.

By defining data explicitly, programmers can ensure proper memory allocation, enforce type safety, and facilitate better understanding and data definitions of the code.

Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop. True or False?

Answers

Answer:

Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop.

True

Explanation:

It has been established that most technicians, instead of overhauling the defective power steering pumps, prefer to install rebuilt or revamped pumps or even new pumps when they could have overhauled the unit themselves.  Some are afraid that leakage could occur again.  They are not confident enough to do the overhauling in-house or some claim that they do not have the time and other tools to carry out the overhauling.  Acknowledgedly, overhauling a power steering pump is not a job for the novice.  They require experienced and skilled hands to do the hard work.
