Scale ratios are used to enlarge or compress an image.

The width of the wall on the drawing is \(\frac{1 }{2}\ inches\)

The scale is given as:

\(Scale = 1 :24\)

The scale ratio is represented as:

\(Scale = Drawing : Actual\)

So, we have:

\(Drawing : Actual = 1 :24\)

Substitute 12 for Actual

\(Drawing : 12 = 1 :24\)

Express as fraction

\(\frac{Drawing }{ 12} = \frac{1 }{24}\)

Multiply both sides by 12

\(12 \times \frac{Drawing }{ 12} = \frac{1 }{24} \times 12\)

\(Drawing = \frac{1 }{2}\)

Hence, the width of the wall on the drawing is \(\frac{1 }{2}\ inches\)

The correct answer is According to P = V I and P = V/I, the source's power (P) input to the circuit is determined.

P = E/t is the equation, where P stands for power, E for energy, and t for time in seconds. According to this equation, power is defined as the amount of energy consumed per unit of time. Ohm's Law states that the electrical current in a circuit may be estimated by dividing the voltage by the resistance in the first iteration of the calculation, I = V/R. In other words, the voltage and resistance are inversely related to the current and directly proportional to each other. Ohm's Law describes the connection between current, voltage, and resistance. This asserts that, given the temperature is constant, the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance.

Answer:

a) \(L = 1.5\)

\(L_q = 0.9\)

\(W = \dfrac{1 }{8 } \, hour\)

\(W_q = \dfrac{3}{40 } \, hour\)

\(P = \dfrac{3}{5 }\)

b) The new backacter should be recommended

c) The additional backacter should not be deployed

Explanation:

a) The required parameters are;

L = The number of customers available

\(L = \dfrac{\lambda }{\mu -\lambda }\)

μ = Service rate

\(L_q\) = The number of customers waiting in line

\(L_q = p\times L\)

W = The time spent waiting including being served

\(W = \dfrac{1 }{\mu -\lambda }\)

\(W_q\) = The time spent waiting in line

\(W_q = P \times W\)

P = The system utilization

\(P = \dfrac{\lambda }{\mu }\)

From the information given;

λ = 12 trucks/hour

μ = 3 min/truck = 60/3 truck/hour = 20 truck/hour

Plugging in the above values, we have;

\(L = \dfrac{12 }{20 -12 } = \dfrac{12 }{8 } = 1.5\)

\(P = \dfrac{12 }{20 } = \dfrac{3}{5 }\)

\(L_q = \dfrac{3}{5 } \times \dfrac{3}{2 } = \dfrac{9}{10 } = 0.9\)

\(W = \dfrac{1 }{20 -12 } = \dfrac{1 }{8 } \ hour\)

\(W_q = \dfrac{3}{5 } \times \dfrac{1}{8 } = \dfrac{3}{40 } \, hour\)

(b) The service rate with the new backacter = 1.5 minutes/truck which is thus;

μ = 60/1.5 trucks/hour = 40 trucks/hour

\(P = \dfrac{12 }{40 } = \dfrac{3}{10}\)

\(W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)

\(W_q = \dfrac{3}{10 } \times \dfrac{1}{38 } = \dfrac{3}{380 } \, hour\)

λ = 12 trucks/hour

Total cost = \(mC_s + \lambda WC_w\)

m = 1

\(C_s\) = GH¢ = 1300

\(C_w\) = 400

Total cost with the old backacter is given as follows;

\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)

Total cost with the new backacter is given as follows;

\(1 \times 1300 + 12 \times \dfrac{1}{38} \times 400 = \$ 1,426.32\)

The new backacter will reduce the total costs, therefore, the new backacter is recommended.

c)

Here μ = 3 min/ 2 trucks = 2×60/3 truck/hour = 40 truck/hour

\(\therefore W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)

Total cost with the one backacter is given as follows;

\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)

Total cost with two backacters is given as follows;

\(2 \times 1000 + 12 \times \dfrac{1}{38} \times 400 = \$ 2,126.32\)

The additional backacter will increase the total costs, therefore, it should not be deployed.

C. 14.55

Explanation:

12 x 10 = 120

120 divded by 10 is 12

so now we do the left side

7 x 3 = 21 divded by 10 is 2

so now we have 14

and the remaning area is 0.55

so 14.55

Based on the code given , the Step 1  is done by enforcing maximum() and min() in ARM7 assembly while Step 2  is done by enforcing the main while circle in ARM7 assembly.

To apply the maximum() and min() functions in ARM7 assembly, we can use some instructions to optimize the law and code speed. There is one possible way to do it based on the image attached.

Therefore, To apply the main while loop, we need to check if the left over of the division between result and d isn't zero, and if so, add c to affect. We can use the SWI 0x6 instruction to gain the balance of the division.

See text below

We will translate the following C function, which calculates the Lowest Common Multiple (1cm) between two positive numbers, into ARM7 assembly:

unsigned int lcm(unsigned int a, unsigned int b)

{

(unsigned int c, d, result; // cannot be translated)

c = max(a, b); // i.e. c-a if a >= b, otherwise c=b d = min(a, b); // same, but vice-versa

result = c;

while ((result % d) != 0) {

}

result = result + c;

}

(return(result);

// cannot be translated)

In doing so, you are asked to optimize the assembly code for execution speed. i.e., a) fewest number of cycles, taking into account pipeline emptying/refilling on branch instructions for example, and b) fewest number of instructions.

Disregard the first/last lines of the lcm() function, which cannot be translated into assembly. This exercise is broken into these two steps:

1. First, implement the two successive lines min() and max() in ARM7 assembly:

c = max(a, b); // i.e. c-a if a>=b, otherwise c=b

d = min(a, b); // same, but vice-versa

[Hint 1]: Remember that the function's arguments, a and b, will be found in registers r0 and rl respectively. Every other register is free for you to use in your code. Remember to use conditional instructions whenever possible, to optimize code density and execution speed.

2. Implement the main while loop in ARM7 assembly.

[Hint 2]: The remainder of a division (i.e., the “modulo” operation %) can be obtained by relying on the BIOS, using the ARM7 instruction: SWI 0x6 (which cannot be conditional) after placing the input in the appropriate, predefined registers (see lecture notes), which cannot be selected/changed, and reading the output from the appropriate register.

Remember to comment each line of your program to explain what your code does.

Diffusion is the process of mass transport resulting from a gradient in concentration. In a diffusion couple, two different materials are brought into contact, and diffusion.

The diffusion process is characterized by Fick's laws of diffusion, which relate the diffusion flux to the concentration gradient. For steady-state diffusion, the flux is constant and given by:J = -D(dC/dx)where J is the diffusion flux, D is the diffusion coefficient, C is the concentration, and x is the position along the diffusion path.The concentration profile in the diffusion couple can be calculated using the diffusion equation:dC/dt = D(d^2C/dx^2)where t is time.The diffusion coefficient is a measure of how quickly atoms can move through a material. It depends on temperature, crystal structure, and the nature of the impurity. The concentration profile depends on the initial concentrations and the diffusion coefficient.In a diffusion couple, the composition of the materials changes as diffusion occurs.

The work done by a 10 HP motor when it raises a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

Define work. Explain the rate of doing work.

Work is the energy that is moved to or from an item by applying force along a displacement in physics. For a constant force acting in the same direction as the motion, work is easiest expressed as the product of force magnitude and distance traveled.

Since the force transfers one unit of energy for every unit of work it performs, the rate at which work is done and energy is used are equal.

Solution Explained:

Given,

Weight = 1000N and distance = 5m

A/Q, the work here is done in lifting then

Work = (weight) × (distance moved)

         = 1000 X 5

         = 5000Nm or 5000J = 5kJ

Therefore, the work done in lifting a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

Both insulators result in the same heat loss, which is 812.3 W. Therefore, in terms of minimizing heat loss, it doesn't matter which insulator is covered outside.

To calculate the heat loss, we can use the formula for overall heat transfer:

Q = U * A * ΔT

Where:

- Q is the heat loss (W)

- U is the overall heat transfer coefficient (W/m².K)

- A is the surface area of the pipe (m²)

- ΔT is the temperature difference between the steam and the surrounding air (K)

First, let's calculate the surface area of the pipe. The circumference of the pipe can be calculated as:

C = π * diameter = 3.1416 * (3 in. * 0.0254 m/in.) = 0.2384 m

The surface area can then be calculated as:

A = 2 * π * r * L

- r is the radius of the pipe (m), which is half the diameter

- L is the length of the pipe (m)

Assuming a pipe length of 1 meter:

r = 0.5 * (3 in. * 0.0254 m/in.) = 0.0381 m

A = 2 * π * 0.0381 * 1 = 0.2393 m²

Now, we can calculate the overall heat transfer coefficient (U) using the convective heat transfer coefficient (h) and the thermal conductivities of the insulators:

U = 1 / (1 / h + δ1 / k1 + δ2 / k2)

- δ1 and δ2 are the thicknesses of insulator A and insulator B, respectively (m)

- k1 and k2 are the thermal conductivities of insulator A and insulator B, respectively (W/m.K)

Assuming δ1 = δ2 = 0.025 m (2.5 cm):

U = 1 / (1 / 15 + 0.025 / 0.04 + 0.025 / 0.20) = 4.245 W/m².K

Now, we can calculate the temperature difference (ΔT):

ΔT = Ts - Ta = 100 - 20 = 80 K

Finally, we can calculate the heat loss (Q) for both insulators:

Q_A = U * A * ΔT = 4.245 * 0.2393 * 80 = 812.3 W

Q_B = U * A * ΔT = 4.245 * 0.2393 * 80 = 812.3 W

Both insulators result in the same heat loss, which is 812.3 W. Therefore, in terms of minimizing heat loss, it doesn't matter which insulator is covered outside.

However, it's worth noting that insulator A has a lower thermal conductivity, which means it is a better insulator and can potentially provide better thermal performance in other aspects such as temperature gradients across the insulation.

The major and minor stresses are as 2060.59 psf, -310.59 psf and 1185.59 psf.

Explanation:

The major and minor principal stresses are given as follows:

\(\sigma_{max}=\dfrac{\sigma_x+\sigma_y}{2}+\sqrt{\left(\dfrac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}\)

\(\sigma_{min}=\dfrac{\sigma_x+\sigma_y}{2}-\sqrt{\left(\dfrac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}\)

Here

So the formula becomes

\(\sigma_{max}=\dfrac{\sigma_x+\sigma_y}{2}+\sqrt{\left(\dfrac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}\\\sigma_{max}=\dfrac{1750+0}{2}+\sqrt{\left(\dfrac{1750-0}{2}\right)^2+(800)^2}\\\sigma_{max}=875+\sqrt{\left(875)^2+(800)^2} \\\sigma_{max}=875+\sqrt{765625+640000}\\\sigma_{max}=875+1185.59\\\sigma_{max}=2060.59 \text{psf}\)

Similarly, the minimum normal stress is given as

\(\sigma_{min}=\dfrac{\sigma_x+\sigma_y}{2}-\sqrt{\left(\dfrac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}\\\sigma_{min}=\dfrac{1700+0}{2}-\sqrt{\left(\dfrac{1700-0}{2}\right)^2+(800)^2}\\\sigma_{min}=875-\sqrt{(875)^2+(800)^2}\\\sigma_{min}=875-\sqrt{765625+640000}\\\sigma_{min}=875-1185.59\\\sigma_{min}=-310.59 \text{ psf}\)

The maximum shear stress is given as

\(\tau_{max}=\dfrac{\sigma_{max}-\sigma_{min}}{2}\\\tau_{max}=\dfrac{2060.59-(-310.59)}{2}\\\tau_{max}=\dfrac{2371.18}{2}\\\tau_{max}=1185.59 \text{psf}\)

The conversion of electrical energy into mechanical energy in an electric motor is made possible by the interaction between magnetic fields, which produces the necessary force to generate motion.

An electric motor works on the principle of electromagnetism, which involves the interaction between an electric current and a magnetic field. When an electric current is passed through a wire that is placed within a magnetic field, the wire experiences a force and starts to move.

When an electric current is passed through the wire, it creates a magnetic field that interacts with the magnetic field of the permanent magnet or electromagnet.

This interaction produces a force that causes the coil to rotate around the metal core, creating mechanical energy.The rotation of the coil is then transferred to the motor's shaft, which is connected to the mechanical system that needs to be powered.

The mechanical energy produced by the motor can be used to drive various types of machinery, such as fans, pumps, or conveyor belts, depending on the specific application.
