q 1: what value is stored in 0×10000008 on a big-endian machine? q 2: what value is stored in 0×10000008 on a little-endian machine?

The statement "In a low pass filter, the cutoff frequency is affected only by the feedback resistor value, not the input resistor" is false.

What is a low pass filter? A low-pass filter is an electronic circuit that allows signals with frequencies lower than a certain threshold to pass through while filtering out signals with higher frequencies. The cutoff frequency is the frequency point at which the filter starts to attenuate the signal. The cutoff frequency can be changed by varying the value of the input and feedback resistors. In a low-pass filter, the cutoff frequency is determined by both the input resistor and the feedback resistor values. As a result, the given statement is false. The cutoff frequency in a low-pass filter is determined by the input and feedback resistor values. The formula for the cutoff frequency in a simple low-pass filter is given as :fc = 1 / (2 * π * R * C)where fc is the i cutoff frequency, R is the resistor value, and C is the capacitor value. In the given formula, both the resistor and capacitor  the cutoff frequency.

Both technicians are partially correct, but neither of them is entirely accurate.

The expansion valve does play a role in preventing the evaporator from freezing, but it is not the only component responsible for this task. The expansion valve regulates the flow of refrigerant into the evaporator, which helps to maintain the proper temperature and pressure in the system. On the other hand, cycling the clutch also plays a role in preventing the evaporator from freezing, but it is not the primary mechanism. The clutch engages and disengages the compressor, which regulates the pressure in the refrigeration system. When the pressure drops too low, the evaporator can freeze. Therefore, both technicians are partially correct.

The average cycle time is 94.85 seconds. The time required to complete the batch is 227,640 seconds, or approximately 63.23 hours

(a) Average Cycle Time:

The cycle time can be calculated as the sum of the setup time, processing time per cycle, and part handling time per cycle, divided by the number of parts produced per cycle.

Cycle Time = (Setup Time + Processing Time + Part Handling Time) / Number of Parts Produced

Setup time = 3.0 hours = 180 minutes

Processing time per cycle = 1.60 minutes x 2 = 3.20 minutes

Part handling time per cycle = 45 seconds x 2 = 1.50 minutes

Irregular work element time = 3.0 minutes

Cycle Time = (180 + 3.20 + 1.50 + 3.0) / 2 = 94.85 seconds

Therefore, the average cycle time is 94.85 seconds.

(b) Time to Complete the Batch:

To calculate the time required to complete the batch, we need to multiply the batch quantity by the cycle time.

Time to Complete Batch = Batch Quantity x Cycle Time

Time to Complete Batch = 2,400 x 94.85 seconds = 227,640 seconds

Therefore, the time required to complete the batch is 227,640 seconds, or approximately 63.23 hours.

(c) Average Production Rate:

The average production rate can be calculated as the batch quantity divided by the time to complete the batch.

Average Production Rate = Batch Quantity / Time to Complete Batch

Average Production Rate = 2,400 / 227,640 seconds = 0.0105 units per second

Therefore, the average production rate is 0.0105 units per second.

Technician B is correct. A receiver/dryer supplies refrigerant vapor to the expansion valve.

A receiver/dryer is a component in the refrigeration system that receives refrigerant vapor from the compressor and cools it to a liquid state. It also removes any moisture and contaminants from the refrigerant stream. A receiver/dryer is usually placed in the high-pressure side of the system, after the condenser and before the expansion valve.

A receiver/dryer operates in two phases: drying and storage. In the drying phase, the desiccant absorbs any moisture that has accumulated in the system. Then, in the storage phase, the refrigerant is kept in the receiver/dryer to ensure that a steady flow of refrigerant reaches the expansion valve, which is typically the next component in the system after the receiver/dryer.

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

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.

The new discharge may remain roughly the same or could even increase slightly, depending on the exact values of width, depth, and velocity.

The discharge of a river is the volume of water that passes through a given cross-section of the river per unit of time. It is calculated as the product of the cross-sectional area of the river channel (width times depth) and the flow velocity.

Discharge (Q) = Width (W) × Depth (D) × Velocity (V)

Given the following changes:

Channel depth (D) decreased to 1 ft

Width (W) stayed at 10 ft

Flow velocity (V) increased to 9 ft/sec

The new discharge (Q') can be calculated as:

Q' = W × D' × V'

Where D' is the new channel depth of 1 ft, and V' is the new flow velocity of 9 ft/sec.

An incompressible fluid, like the water in a river, has a constant mass flow rate along a streamline according to the fluid mechanics principle of continuity. This means that, in the absence of external forces, the product of the cross-sectional area and the flow velocity is constant. Here, we make the assumption that the river is in a stable state and that no outside factors are changing its flow.

When the channel depth (D) decreases to 1 ft, but the width (W) stays the same at 10 ft, the cross-sectional area (W × D') of the river decreases. However, the flow velocity (V') increases to 9 ft/sec.

As a result, if the continuity principle is valid, the decline in channel depth is balanced by the rise in flow velocity. This indicates that depending on the precise values of breadth, depth, and velocity, the new discharge (Q') may either stay nearly the same or perhaps significantly rise.

Technician A is correct that the adjusting nut should be rotated clockwise to decrease free travel when adjusting a manual slack adjuster on an S-cam foundation brake. Technician B is not correct in this case.

When adjusting a manual slack adjuster on an S-cam foundation brake, the lock collar should be retracted and the adjusting nut should always be rotated clockwise to decrease free travel.

The S-cam foundation brake is a type of drum brake commonly used in heavy-duty vehicles. It uses an S-shaped camshaft to force the brake shoes against the brake drum, resulting in friction and slowing down the vehicle. The slack adjuster is a critical component of the S-cam brake system that helps to maintain proper clearance between the brake shoes and the drum, known as "slack" or "free travel".

When adjusting the slack adjuster, rotating the adjusting nut clockwise will move the S-cam in the direction that reduces the slack or free travel, thus bringing the brake shoes closer to the brake drum. This will result in improved braking performance. On the other hand, rotating the adjusting nut counterclockwise will increase the slack or free travel, which is not desirable as it may result in reduced braking efficiency and longer stopping distances.

   Continuity equation:

   Q = A1V1 = A2V2

   where Q is the volumetric flowrate, A1 and A2 are the cross-sectional areas of the venturi meter at points 1 and 2 respectively, and V1 and V2 are the velocities of the fluid at points 1 and 2 respectively.

   Bernoulli's equation:

   P1 + 1/2ρV1^2 + ρgh1 = P2 + 1/2ρV2^2 + ρgh2

   where P1 and P2 are the pressures at points 1 and 2 respectively, ρ is the density of the fluid, g is the acceleration due to gravity, h1 and h2 are the heights of the fluid columns in the manometer at points 1 and 2 respectively.

   Hydrostatic equation:

   P3 + ρgh3 = Patm

   where P3 is the pressure in the air column of the manometer, h3 is the height of the air column, and Patm is the atmospheric pressure.

b) To find the discharge, we need to solve the above equations for Q. We can rearrange the continuity equation to get V2 = (A1/A2)V1, and substitute it into Bernoulli's equation to eliminate V2:

P1 - P2 = (ρ/2)(V1^2 - (A2/A1)^2V1^2) + ρg(h2 - h1)

Substituting the pressure difference (P1 - P2) with the manometer reading (h1 - h2), and solving for V1:

V1 = √[(2g/h)(h1 - h2 + (P1 - P2)/ρ)]

Substituting V1 into the continuity equation:

Q = A1V1

c) According to Bernoulli's equation, the total pressure at point 2 is lower than the total pressure at point 1 because the velocity of the fluid at point 2 is higher than at point 1. This is known as the Bernoulli's principle.

d) To find the force acting on the tube for a pressure of 2 kPa at point 1, we need to know the cross-sectional area of the tube and the pressure difference across it. Assuming a circular cross-section with a diameter of 1 cm, the area is:

A = πd^2/4 = π(0.01 m)^2/4 = 7.85×10^-5 m^2

The pressure difference is equal to the manometer reading, which is the height difference between the two fluid columns:

ΔP = ρgh = 1000 kg/m^3 × 9.81 m/s^2 × (h1 - h2)

Substituting the given pressure of 2 kPa (2000 Pa) for P1, and solving for the height difference:

h1 - h2 = 0.204 m

Substituting the values into the equation for pressure:

ΔP = 1000 kg/m^3 × 9.81 m/s^2 × 0.204 m = 2002 Pa

The force acting on the tube is given by:

Stream banks that are steep-sided have the highest potential to produce mass movement of rock into a flowing tributary.


Steep-sided stream banks have a higher potential for producing mass movement of rock into a flowing tributary because the steep slopes can destabilize and cause rocks and soil to fall into the stream. This process is known as mass wasting or mass movement. The steeper the slope, the higher the potential for mass movement to occur. In contrast, gently sloping stream banks may not have as high a potential for mass movement because the slope is less steep and therefore less prone to destabilization. Stream banks with multiple point bars or oxbow lakes may also be less prone to mass movement because the deposition of sediment in these features can stabilize the bank and make it less susceptible to erosion. Overall, the steepness of the stream bank is a key factor in determining the potential for mass movement.

When it comes to crack growth at a lower applied stress, the situation that would result in such an occurrence is a crack tip with a large radius of curvature. This is the correct option.

Fatigue crack growth refers to the process by which tiny cracks grow and grow in materials subjected to repeated loading. A crack is a slit, a fissure, or a weakness in a substance that extends through it. Cracks are dangerous, particularly in structures, because they have the potential to grow and propagate until they reach a catastrophic level.

A small radius of curvature on a crack tip is less probable to cause crack growth at lower applied stresses. A small radius of curvature has a tendency to magnify the stresses and make them much more serious. A large radius of curvature, on the other hand, makes it easier for stresses to distribute, making it less likely for a crack to grow at lower applied stresses.

Thus, the situation that will result in crack growth at a lower applied stress is a crack tip with a large radius of curvature.

Undulations in the bottom surface of a soft rubber layer under its own gravitational force can be explained qualitatively based on energy minimization, where the undulations reduce the gravitational potential energy of the layer.

When a soft rubber layer is under its own gravitational force, it deforms and experiences stress due to the weight of the material. According to the neo-Hookean model, the stress state in the rubber layer can be calculated based on the strain energy density function. The undulation on the bottom surface of the rubber layer can be explained based on energy minimization. The deformation of the rubber layer under gravity induces a curvature on the surface of the layer, which increases the strain energy of the material. The undulation phenomenon occurs due to the elastic instability of the material, where the elastic energy of the material is reduced by forming a pattern of wrinkles on the surface. This phenomenon is a result of the balance between the elastic energy and gravitational potential energy in the rubber layer.
