(a) The free rotational motion of an axially symmetric rigid body with Ia = 2It, where Ia is the axial moment of inertia and It is the transverse moment of inertia. We are to find the largest possible value of the angle between ω and H. The hint is that we should consider the angular momentum magnitude ∣H∣ fixed and vary the kinetic energy T.

The angular momentum H is given by:H = IωsinθWhere I = It + Ia, ω is the angular velocity, and θ is the angle between the vectors H and ω. So the angular momentum magnitude ∣H∣ is given by:|H| = IωsinθBut we are to consider ∣H∣ to be fixed. So Iωsinθ is constant. Therefore, the product Iω should be constant as well. Thus, we have:Iω = constantThis is known as the conservation of angular momentum.

The kinetic energy T is given by:T = (1/2)Iaω² + (1/2)Itω²= (1/2)(Ia + It)ω²= (3/4)Itω²(Using Ia = 2It)The kinetic energy T is proportional to ω². So as T varies, ω varies as well. However, Iω is constant. As T increases, ω increases, and as T decreases, ω decreases. Since ∣H∣ = Iωsinθ is constant, the angle θ between ω and H varies with T. So we have sinθ varying with T. The angle θ will be largest when sinθ is largest.

Thus, sinθ should be maximized. The largest value that sinθ can take is 1. So θ is maximized when sinθ = 1 or θ = 90°. Therefore, the largest possible value of the angle between ω and H is 90°. The angular momentum vector H and the angular velocity vector ω are perpendicular to each other.

(b) We are to find the critical value of kinetic energy that results in the largest angle between ω and H. We know that the kinetic energy T is given by:T = (3/4)Itω² (Using Ia = 2It)Now, we are to find the maximum value of T. We know that T is proportional to ω². Thus, we can find the maximum value of T by maximizing ω². But Iω is constant. So we have:Iω = constant=> ω = constant/IThe kinetic energy T is given by:T = (3/4)Itω²= (3/4)It(constant/I)²= (3/4)(It/I²)constant²= (3/4)(It/Ia)constant²(Using Ia = 2It), The critical value of kinetic energy that results in the largest angle between ω and H is (3/4)(It/Ia)constant².

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Solution :

Given

The number of line that can be written by printer per page = 50 lines

The number of characters that can be written by printer per page = 80 characters.

Number of pages that can be written per minute = 6 pages

The speed for writing characters to the printer can be found by

= 50 x 80 x 6

= 400 characters per sec

In one second the printer has the writing speed of 400 character.

Now each of the character uses = 50 µsec of the CPU time for interrupt.

So in each second, the interrupt overhead = 20 msec

Now using the interrupt driven input/output,  980 msec time can be available for other work.

Thus, the interrupt overhead charges only 2 percent of the CPU, that will hardly affect the program to run.

We know that the gauge pressure of the tank is 552 psi, which means the pressure inside the tank is 552 psi above atmospheric pressure. To find the total force the cover is experiencing, we need to calculate the force based on the pressure and the surface area of the cover.

First, we need to convert the gauge pressure to absolute pressure:
Absolute pressure = Gauge pressure + Atmospheric pressure
Assuming the atmospheric pressure is 14.7 psi, the absolute pressure in the tank is:
Absolute pressure = 552 psi + 14.7 psi = 566.7 psi

Section Key Terms

kinetic friction static friction

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The interior dimensions of the box in feet are approximately 1.47639 ft x 0.65617 ft x 0.24606 ft.

To determine the volume of air in the box, we first need to convert the given dimensions from meters to feet.

The interior dimensions of the box are 0.45 m x 0.2 m x 0.075 m.

Converting these dimensions to feet:

1 meter = 3.28084 feet

0.45 m x 3.28084 ft/m = 1.47639 ft

0.2 m x 3.28084 ft/m = 0.65617 ft

0.075 m x 3.28084 ft/m = 0.24606 ft

So, the interior dimensions of the box in feet are approximately 1.47639 ft x 0.65617 ft x 0.24606 ft.

Next, we need to calculate the total volume occupied by the twelve oranges. Each orange has a diameter of 2.5 inches, which gives a radius of 1.25 inches or 0.10417 ft (since 1 inch = 0.08333 ft).

The volume of a single orange can be calculated using the formula for the volume of a sphere:

V = (4/3) * π * r^3

Substituting the radius (0.10417 ft) into the formula:

V_single_orange = (4/3) * π * (0.10417 ft)^3

Now, to find the total volume occupied by twelve oranges:

V_total_oranges = V_single_orange * 12

Finally, to determine the volume of air in the box, we subtract the total volume occupied by the oranges from the total volume of the box:

V_air = (1.47639 ft * 0.65617 ft * 0.24606 ft) - V_total_oranges

Calculating the values and subtracting the volumes, we find the volume of air in the box in cubic feet.

For an ideal op-amp, the op-amp's input current will be zero. An ideal op-amp is assumed to have infinite input impedance, meaning that no current flows into or out of its input terminals. This implies that the op-amp draws no current from the input source.

In practical op-amps, the input current is not exactly zero but is extremely small (typically in the picoampere range). This input current is often negligible and can be considered effectively zero for most applications. However, it is important to note that this ideal condition assumes that the op-amp is operating within its specified limits and under typical operating conditions.

In reality, external factors such as temperature, supply voltage, and manufacturing variations can affect the op-amp's input current, but for the purposes of most circuit analysis and design, it can be assumed to be zero.
