Given a rigid container with 3.5 kg of motor oil, we need to determine the rate of specific energy increase when heat is transferred to the oil at a rate of 1 W, and 1.5 W of power is applied to the stirring device.

The rate of specific energy increase can be calculated by considering the rate of heat transfer and the rate of work done by the stirring device.

The rate of specific energy increase (dU/dt) is given by the sum of the rate of heat transfer (Qdot) and the rate of work done (Wdot) by the stirring device. Mathematically, it can be expressed as:

dU/dt = Qdot + Wdot

In this case, the rate of heat transfer is given as 1 W, and the rate of work done by the stirring device is 1.5 W. Substituting these values into the equation, we have:

dU/dt = 1 W + 1.5 W = 2.5 W

Therefore, the rate of specific energy increase for the motor oil is 2.5 W. This means that the energy content of the oil is increasing at a rate of 2.5 joules per second (Watt).

It's important to note that the specific energy increase represents the rate of change of energy per unit mass of the motor oil. In this case, the specific energy increase is calculated based on the total mass of the oil in the container (3.5 kg).

Updated question

The big ben clock tower in London has clocks on all four sides. If each clock has a minute hand that is 11.5 feet in length, how far does the tip of each hand travel in 52 minutes?

The distance traveled by the tip of the minute hand of the clock would be 62.59 ft

Explanation:

Let us assume the shape of the clock is circular.

the minute hand is equal to the radius = 11.5 ft

Diameter = radius x 2

Diameter = 11.5 x 2 = 23 ft

The distance traveled by the tip of the minute hand can be calculated thus;

the fraction of the circumference traveled by the minute hand would be;

52/60 = 0.8667

Circumference of the clock would be;

C = pi x d

where C is the circumference

pi is a constant

d is the diameter

C = 3.14 x 23

C = 72.22 ft

Therefore the fraction of the circumference covered by the minute hand would be;

72.22 ft x 0.8667 = 62.59 ft

Therefore the distance traveled by the tip of the minute hand of the clock would be 62.59 ft

To obtain the time vs. settlement curve for a period of 50 years, we need to follow the following steps:

1. Compute Cv as a function of Hdr with given information:
We know that the settlement of the layer is 30 mm in 300 days, which corresponds to 25% consolidation. From the laboratory consolidation test, we can obtain the coefficient of consolidation (Cv) as follows:
Cv = (sH^2)/(t50)
where s is the settlement, H is the thickness of the layer, t50 is the time required for 50% consolidation. Since we know that the layer has already undergone 25% consolidation, t50 can be calculated as:
t50 = (2.303t90)/(log(e2))
where t90 is the time required for 90% consolidation. From the laboratory test, we can assume a value of t90 = 10 years. Substituting these values, we get:
t50 = (2.303 x 10)/(log(e2)) = 14.16 years
Now, we can calculate Cv as:
Cv = (30 x 0.1^2)/(14.16 x 0.25) = 0.0085 m^2/year

2. Develop an expression for time factor, T, as a function of real time, t:
The time factor, T, is given by:
T = (Cv t)/H^2
where t is the real time and H is the thickness of the layer. Substituting the values we get:
T = (0.0085 t)/(0.1^2)

3. Tabulate t, T, U and Settlement for various real time values, t:
Using the expression for time factor, we can calculate the settlement for any given time period as follows:
U = Uo (1- e^-T)
where Uo is the initial settlement. Since the layer has already undergone 25% consolidation, the initial settlement can be calculated as:
Uo = (s25 x H)/100 = (30 x 0.1)/100 = 0.003 m
Using this value, we can tabulate the settlement for various time periods as follows:

t (years) T U Settlement (mm)
0 0 0.0000 0.000
1 0.0061 0.0018 0.006
2 0.0122 0.0036 0.012
5 0.0304 0.0089 0.029
10 0.0607 0.0178 0.055
20 0.1214 0.0356 0.095
30 0.1821 0.0533 0.125
40 0.2429 0.0711 0.149
50 0.3036 0.0889 0.170

Thus, we can see that the settlement increases with time and reaches a steady state after around 50 years. The rate of settlement decreases with time due to the consolidation of the clay layer. The direction of drainage does not affect the settlement as long as the layer is fully saturated.

The maximum shear stress is  R = 25 MPa

Since the Von Mises stress in this case is less than the yield stress

From the circle, we can read off the principal stresses  as the two intersections of the circle with the horizontal axis. In this case, the principal stresses are:

σ1 = σavg + R = 35 MPa

σ2 = σavg - R = -15 MPa

The maximum shear stress is given by the radius of the circle, which is equal to half of the difference between the two principal stresses:

τmax = R = 25 MPa

In order to determine if the plate will yield under uniaxial tension with a yield stress of 80 N/mm², we first need to convert the units of the stress values we obtained earlier from MPa to N/mm²:

σ1 = 35 MPa = 35 N/mm²

σ2 = -15 MPa = -15 N/mm²

Substituting these values into the Von Mises yield criterion equation, we get:

Obtain the properties of air at room temperature from molar mass, gas constant and critical point properties table

Gas constant R = 0.3704 psia ft³ / ibm.R

Express the thermal efficiency of an ideal stirling engine

\(n_{th}=\frac{W_{net}}{Q_{in}} =1-\frac{T_L}{T_H}\)

Here, network done by the stirling engine is \(W_{net}\)

heat input to the engine is \(Q_{in}\)

Temperature of the heat source is \(T_H\)

Temperature of the sink is \(T_L\)

substitute 535 for  \(T_L\) , 2Btu for \(W_{net}\) , 5Btu for \(Q_{in}\)  to find \(T_H\)

\(\frac{2Btu}{5Btu}=1-\frac{535R}{T_H} \\\\T_H=\frac{535}{0.6}\\\\=891.7R\)

Answer:

Both technicians are right.

Explanation:

Unibody vehicles have their body, floor plan, and chassis formed into a single structure. These vehicles are generally lighter and more rigid than body-over-frame vehicles. The fact that they are lighter than body-over-frame vehicles means that they have lesser weight to power ratio, which means compared to a body-over-frame vehicle, they will use a lesser amount of fuel to move through the same distance than the body-over-frame would use. This makes unibody vehicles more fuel efficient. Body-over-frame types of vehicles  are made up of a separate body, mounted on a relatively rigid vehicle frame or chassis that carries the powertrain (the engine and drivetrain). This was the original method of building automobiles, is now used mainly for pickup trucks and SUVs.

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

According to the statement “firms that seek a cost advantage should adopt a learning curve strategy”, learning curves describe the improvement in production efficiency or reduced cost per unit in time, especially early in the production process, with practice and increasing output.

In summary, learning curves are an excellent strategy for firms that seek a cost advantage. However, whether or not a firm that seeks to differentiate their products should adopt a learning curve strategy is up to the specific company's product and strategy.

Firms that want to achieve a cost advantage should adopt the learning curve strategy as they’ll learn how to produce products more efficiently and increase their output over time. This is important to note that it's not always easy to implement a learning curve strategy due to the initial upfront costs involved in the process. However, the process is worth it as it leads to long term cost savings and boosts the company's competitiveness in the market. On the other hand, the statement that “firms that seek to differentiate their products should not” adopt a learning curve strategy may be true or not. This statement implies that learning curves might undermine the quality and unique features of the products. However, this statement is not absolute. It all depends on how learning curves are implemented. Companies can still learn how to produce better quality products more efficiently over time.

When the brake pedal is pressed, hydraulic pressure is applied to the brake system which in turn forces the brake shoes to press against the drum or rotor, slowing down or stopping the car.

Brake shoes are a type of braking system used in some older vehicles and heavy-duty applications. They are typically made of metal and lined with friction material, such as asbestos or ceramic, which provides the necessary stopping force. Brake shoes stop a car by exerting pressure on the brake drum or rotor, which is located behind the wheel and rotates with the wheel. When the driver applies the brake pedal, the brake shoes are pushed against the drum or rotor, creating friction and slowing down the wheel. This slows down the car as a whole, allowing it to come to a stop. Proper maintenance and regular replacement of brake shoes are crucial for safe and reliable braking performance.

Explanation:

The critical path is the longest path through a project network diagram, which includes all the activities that are critical to the completion of the project. In order to calculate the critical path, you will need to follow these steps:

Identify all the activities that need to be completed for the project.

Determine the duration of each activity. This can be estimated based on past experience or expert opinion, or by conducting time studies.

Create a network diagram that shows the sequence of activities and their dependencies. This can be done using software such as Microsoft Project or by drawing a diagram manually.

Identify the earliest start and finish times for each activity, based on the dependencies and durations.

Identify the latest start and finish times for each activity, based on the project deadline.

Calculate the total float or slack for each activity, which is the amount of time that an activity can be delayed without affecting the overall project completion date.

Identify the critical path, which is the longest path through the project network diagram that has zero total float or slack. This means that any delay in one of the activities on the critical path will cause a delay in the overall project completion date.

Once you have identified the critical path, you can focus your attention on managing and monitoring the activities on that path to ensure that the project stays on schedule.
