No, the physical address 346E0 cannot be the starting address for a segment. This is because the starting address of a segment must be aligned with the segment's size or boundary, which is determined by the processor's architecture.

Segment boundaries are defined by 16-byte or 4-byte boundaries, depending on the segment's use. Therefore, the starting address of a segment must be a multiple of 16 or 4, respectively, depending on the segment type.

In the given address 346E0, the last digit is 0, which indicates that it is a multiple of 16. However, we do not have enough information about the processor architecture and segment size to determine whether this is an appropriate starting address for a segment.

In general, when defining a segment, it is important to ensure that the starting address is properly aligned with the segment's boundary to avoid any issues with memory access and processing.

Explanation:

A centrifugal pump's performance can be measured using several parameters, including flow rate, head, power consumption, and efficiency.

Here's how each parameter can indicate how well a centrifugal pump is performing:

Flow rate: This refers to the volume of liquid that the pump is able to move in a given period. Measuring the flow rate can indicate whether the pump is operating at the desired capacity. If the flow rate is too low, the pump may be experiencing some obstruction, while a flow rate that is too high can indicate a pump that is overworked.

Head: This is the energy that the pump imparts to the liquid, expressed in terms of pressure. A high head indicates that the pump is generating sufficient pressure to overcome any resistance in the piping.

Answer:

Explanation:

Since no figure was given, I'll explain how to do this problem theoretically. The formula for shear flow is \(q=\frac{VQ}{I}\) where V is the shear force, Q is the moment of area (more on this later), and I is the moment of inertia.

The first step to solve this problem is to find the resultant internal forces of the beam. This can be done in several ways, but the easiest is to solve the beam statically and draw a shear diagram to determine the maximum shear force V.

The second step to solving this problem is to determine the location of the neutral axis of the cross section if it is not given. The formula for the neutral axis is  \(NA = \frac{\sum y*A}{\sum A}\). The y in this equation represents the middle of the small shapes that the web is divided into. An I-beam can be thought of as 3 rectangles, while a T-beam can be thought of as 2. The A in this formula represents the area of each of the rectangles (an I-beam will have 3 of these and a T-beam will have 2).

The third step for this problem is to find the moment of inertia. There are several formulas for moment of inertia depending on the shape of the cross section. I-beam's and T-beams both can be thought of as multiple rectangles, so they have the same base formula of \(I=\frac{1}{12}bh^3\) where b is the base of the rectangles and h is the height. For I-beams, the easiest way to calculate moment of inertia is to think of the entire cross section as a big rectangle that had two smaller rectangles cut out of it. The formula for this moment of inertia becomes \(I=\frac{1}{12} b_{big}h^{3} _{big}-\frac{1}{6}b_{small}h^{3}_{small}\). Note that this form of moment of inertia already takes into account subtracting 2 small rectangles. For T-beams, this approach will not work, so the parallel axis theorem must be used. The moment of inertia for the T-beam becomes \(I=\frac{1}{12}b_{1} h^{3}_{1} +b_{1}h_{1}dy_{1}^{2} +\frac{1}{12}b_{2} h^{3}_{2} +b_{2}h_{2}dy_{2}^{2}\) where the terms with the subscript 1 represent the first rectangle and the terms with the subscript 2 represent the second rectangle. The dy terms represent the distance from the center of that specific rectangle to the neutral axis.

The fourth step for this problem is to find Q. The formula to find Q is \(Q=\sum y'A'\) where y' represents the distance from the neutral axis to the center of the "wanted" point and A' is the area of the rectangle that has the wanted point at its center. (This would be the area above or below the thickness (t) if you were solving for maximum shear \(\tau=\frac{VQ}{It}\)).

The last step for this problem is to substitute the found values into the formula for shear flow \(q=\frac{VQ}{I}\). V came from step 1, Q came from step 4, and I came from step 3.

To determine the tension in cable CAD and the angle theta which the cable makes at the pulley, we need to apply equilibrium equations to the system. The tension in cable CAD is found to be 300 lb, and the angle theta is 30 degrees

To solve this problem, we first draw a free body diagram of the system. We assume that the tree is stationary, and therefore, in equilibrium. The tension in cable AB is given as 600 lb. Next, we consider the pulley and the cable CAD. The tension in cable CAD is denoted as T. To find the angle theta, we consider the vertical and horizontal components of the force acting on the pulley. The vertical component of the force is equal to the tension in cable AB, which is 600 lb. The horizontal component of the force is equal to the tension in cable CAD, which is T. Since the pulley is in equilibrium, the sum of the vertical and horizontal components of the force is equal to zero.

We can express this equilibrium condition mathematically by using trigonometry. Let the angle that cable CAD makes with the horizontal be theta. Then, the vertical component of the force is 600 sin(theta), and the horizontal component of the force is T cos(theta). Equating the sum of the vertical and horizontal components to zero, we obtain:

600 sin(theta) = T cos(theta)

Solving for T, we get:

T = 600 sin(theta) / cos(theta) = 600 tan(theta)

To find the angle theta, we can use the fact that the sum of the angles in a triangle is 180 degrees. The triangle formed by the pulley and the cables AB and CAD is a right triangle, with the angle opposite cable CAD being 90 degrees. Therefore, the angle opposite cable AB is equal to:

90 - theta

The angle opposite cable AB is also equal to the inverse tangent of the ratio of the opposite and adjacent sides of the triangle. That is:

tan(90 - theta) = 600 / T

Substituting T = 600 tan(theta) and simplifying, we obtain:

tan(90 - theta) = 1 / tan(theta)

Using the identity tan(90 - theta) = cot(theta), we get:

cot(theta) = tan(theta)

Solving for theta, we obtain:

theta = 30 degrees

Substituting theta = 30 degrees into T = 600 tan(theta), we get:

T = 600 tan(30) = 300 lb

Therefore, the tension in cable CAD is 300 lb, and the angle theta is 30 degrees.

Explanation:

To calculate the nominal current per phase for a 3-phase, 75 hp, 440 v induction motor, we need to use the following formula:

I = P / (sqrt(3) x V x EFF x PF)

Where:

I = Current per phase
P = Power in horsepower (75 hp)
V = Voltage (440 V)
EFF = Full-load efficiency (91%)
PF = Power factor (83%)

Plugging in the values, we get:

I = 75 / (sqrt(3) x 440 x 0.91 x 0.83)
I = 75 / (1.732 x 440 x 0.91 x 0.83)
I = 75 / 480.77
I = 0.156 A (rounded to three decimal places)

Therefore, the nominal current per phase for the given 3-phase, 75 hp, 440 v induction motor is 0.156 A. It's worth noting that this value is for full load conditions, and the actual current may vary depending on the motor's load and operating conditions.

We will find the nominal current per phase for a 3-phase, 75 hp, 440 V induction motor with a full-load efficiency of 91% and a power factor of 83%.

Step 1: Convert horsepower (hp) to watts (W).
1 hp = 746 W
75 hp × 746 W/hp = 56,070 W

Step 2: Calculate the input power.
Input power = Output power / Efficiency
Input power = 56,070 W / 0.91 = 61,593.41 W

Step 3: Calculate the total apparent power (S).
Apparent power = Input power / Power factor
S = 61,593.41 W / 0.83 = 74,215.44 VA

Step 4: Calculate the line voltage.
Line voltage = Phase voltage × √3
Line voltage = 440 V × √3 = 762.0 V

Step 5: Calculate the nominal current per phase.
Nominal current = Apparent power / (Line voltage × √3)
Nominal current = 74,215.44 VA / (762.0 V × √3) = 60.4 A

So, the nominal current per phase for this 3-phase, 75 hp, 440 V induction motor with a full-load efficiency of 91% and a power factor of 83% is approximately 60.4 A.
