which is an indication that a pump is cavitating? select one: a. pump does not make any working noises b. a decrease in the throttle will decrease discharge pressure c. an increase in the throttle will increase discharge pressure d. lack of reaction on the pressure gauge to increases in the throttle

Answer:

technician b

Explanation:

Technician A and Technician B are saying about mounting plates. The statement of Technician B says that a chain tensioner may be considered a piece of pulling hardware. Technician B is right.

The component of a joint, handle, or lock that attaches the hardware to a cabinet is called a mounting plate. Doors can be fastened to frames more easily with mounting plates. The part of a joint that matches to the wood is called a mounting plate. Furniture, cabinets, and doors can all use mounting plates.

A sort of mechanical tool called chain tensioner aids in preserving the ideal tension in a chain. Inanition in a chain or belt can result in noise and vibration, as well as make it difficult for the chain to engage with the correct and function properly.

Therefore, technician B is correct.

Answer:

89375 N

Explanation:

Rearrange the formula for normal stress for F:

\(\sigma=\frac{F}{A}\)

\(F=\sigma*A\)

Convert given values to base units:

275 MPa = \(275*10^{6}\) Pa

325 \(mm^{2}\) = 0.000325 \(m^{2}\)

Substituting in given values:

F = \((275*10^{6})*(0.000325)=89375\) N

Answer:

  151.2 N

Explanation:

The upward force at A is 135/(135+325) times the total weight of the generator. The CW torque about point O that produces is ...

  (460 mm)(135/460)(160 kg)(9.8 m/s^2) = 211.68 N·m

For F to produce half that torque, it must be ...

  F(0.7 m) = (211.68 N·m)/2

  F = 211.68 N·m/(1.4 m) = 151.2 N

Answer:

1. --a 10

--b 100 in.

2. --a 4

--b 4

3. --a 2

--b 30 rpm

--c 75 ft.·lb.

4. --a Second class lever

--b 50 lbs.

Explanation:

The Actual Mechanical Advantage, AMA, is given as follows;

\(AMA = \dfrac{F_R}{F_E}\)

Where;

\(F_R\) = The resistance force magnitude

\(F_E\) = The effort force magnitude

1. a. We have;

\(F_R\) = 10 lb.

\(F_E\) = 100 lb.

\(AMA = \dfrac{100 \ lb}{10 \ lb} = 10\)

b. \(Mechanical \ advantage, \ M.A. = \dfrac{Distance \ moved \ by \ load}{Distance \ moved \ by \ effort}\)

The diameter of the axle, d = 2 in.

Let 'D' represent the diameter of the wheel, we have;

The distance moved by the axle, c = π·d

The distance moved by the load, C = π·D

\(M.A. = 10 = \dfrac{\pi \cdot D}{\pi \times 2}\)

∴ 2 × 10 = D

D = 20 in.

The required wheel diameter to overcome the resistance force, D = 100 in.

2. --a The mass of the participants, m = 200 lb.

The depth of the ground of the participants = 20 feet

The effort force = 50 lb

Actual Mechanical Advantage, AMA = 200 lb./(50 lb.) = 4

--b. The number of strands of pulley needed ≈ The mechanical advantage = 4

3. The number of gears on Gear A = 10 teeth

The number of gears on Gear B = 8 teeth

The number of gears on Gear C = 20 teeth

-a. Given that the driver gear = Gear A

The output gear = Gear C

\(The \ gear \ ratio = \dfrac{The \ number \ of \ teeth \ on \ the \ driven \ gear}{The \ number \ of \ teeth \ on \ the \ driver \ gear}\)

The driver gear = The input gear

Therefore, we have;

\(The \ gear \ ratio = \dfrac{20 \ teeth}{10 \ teeth} = 2\)

The gear ratio = 2

-b \(The \ gear \ ratio = \dfrac{The \ driver \ gear\ speed}{The \ driven \ gear\ speed}\)

Therefore, we have;

\(The \ gear \ ratio = 2 = \dfrac{60 \ rpm}{Gear\ C \, speed}\)

\(Gear\ C \, speed = \dfrac{60 \ rpm}{2} = 30 \ rpm\)

-c The output (driven) gear torque at Gear C = 150 ft.·lb.

\(The \ gear \ ratio = \dfrac{Driven \ gear \ torque}{Driver \ gear \ torque}\)

Therefore;

\(2 = \dfrac{150 \ ft \cdot lb}{Driver \ gear \ torque}\)

\(Driver \ gear \ torque = \dfrac{150 \ ft \cdot lb}{2} = 75 \ ft \cdot lb\)

The input (driver) torque at Gear A = 75 ft·lb

4. -a Given that the load is between the effort and the fulcrum, we have;

The type of lever is a second class lever

-b The distance between the load and the fulcrum = 4 feet

The distance between the effort and the fulcrum = 8 feet

We have;

100 lbs × 4 ft. = Effort × 8 ft.

∴ Effort = 100 lbs × 4 ft./(8 ft.) = 50 lbs.

The effort = 50 lbs.

If both the ram air input and drain hole of the pitot system become blocked, the indicated airspeed will: a) increase during a climb.

A ram air input can be defined as an air intake system which is designed and developed to use the dynamic air pressure that is created due to vehicular motion, or ram pressure, in order to increase the static air pressure within the intake manifold of an internal combustion engine of an automobile.

This ultimately implies that, a ram air input allows a greater mass-flow of air through the engine of an automobile, thereby, increasing the engine's power.

In conclusion, indicated airspeed will increase during a climb when both the ram air input and drain hole of the pitot system become blocked.

If all the data is sent in only one segment, the sequence number of that segment would be 21349.

To determine the sequence number of the segment if all the data is sent in only one segment, we need to consider the following:

In a TCP connection, each byte of data is assigned a sequence number. The sequence number represents the byte's position within the stream of data being transmitted.

Given that the first byte is numbered 21050 and the payload is 300 bytes, we can calculate the sequence number for the segment as follows:

Sequence number = First byte number + Payload length - 1

Sequence number = 21050 + 300 - 1

Sequence number = 21349

Therefore, if all the data is sent in only one segment, the sequence number of that segment would be 21349.

Critical load Fcr or buckling load is the value of load that causes the phenomenon of change from stable to unstable equilibrium state.

With that beign said, first it is neessary to calculate the moment of inercia about the x-axis:

\(Ix= \frac{db^3}{12}\\ Ix = \frac{2.(4)^3}{12} = 10.667in\)

Then it is necessary to calculate the moment of inercia about the y-axis:

\(Iy = \frac{db^3}{12}\\ Iy = \frac{4.(2)^3}{12} = 2.662in\)

Comparing both moments of inercia it is possible to assume that the minimun moment of inercia is the y-axis, so the minimun moment of inercia is 2662in.

And so, it is possible to calculate the critical load:

\(Pc\gamma = \frac{2046\pi ^2E.I}{L^2} \\Pc\gamma= \frac{2046.\pi ^2.(1,6.10^3.10^3).2662}{(10.12)^2} \\Pc\gamma= 5983,9db\)

The velocity of airplane will be 317.4 m/s.

The velocity of an airplane flying at a standard altitude of 5 km can be calculated using the stagnation pressure of the pitot tube mounted at the nose.

The stagnation pressure of the pitot tube was measured at 0.957 bar. Assuming the airplane is flying at high subsonic speed and flow is compressible, the velocity of the airplane can be calculated using the equation:

Velocity (v) = sqrt[2*(pstag-pamb)/ρ]

Where pstag is the stagnation pressure (0.957 bar), pamb is the ambient pressure (0.1013 bar at 5 km altitude), and ρ is the air density (1.225 kg/m3).

Plugging in the given values, the velocity of the airplane is 317.4 m/s.

The term for a person who does not share the belief of the dominant religion of a society is "a heathen". The correct option is A.

A society is a group of people who interact with one another on a regular basis, or a large social group that shares the same spatial or social territory and is typically subject to the same political authority and dominant cultural expectations.

"A heathen" is a person who does not share the beliefs of a society's dominant religion.

The term is frequently used to describe someone who is considered uncivilized or primitive because of their religious beliefs, especially in societies where the dominant religion wields significant power and influence.

However, it is important to note that the term can be considered derogatory and offensive, and it is generally more respectful to refer to people of different religious beliefs using neutral or positive terms.
