A sinusoid carrier signal c(t) is defined as: c(t) = 5 cos(10,000ft) A message signal is modulating the above carrier in AM system, expressed as: m(t) = 2 · cos(104nt) a) Find Modulation Index "u". b) Find the B.W of the Base Band signal. c) Find the B.W of the Band Pass signal. d) What is the FL FH and Fc for the band pass signal.

Answers

Answer 1

a) The modulation index "u" for an AM system can be calculated by dividing the peak amplitude of the message signal by the peak amplitude of the carrier signal. The modulation index "u" is 2/5.

b) The bandwidth of the baseband signal in an AM system is equal to twice the frequency of the message signal.

c) The bandwidth of the bandpass signal in an AM system is equal to twice the frequency of the carrier signal.

d) FL (lower cutoff frequency), FH (upper cutoff frequency), and Fc (center frequency) for the bandpass signal depend on the carrier frequency and the bandwidth of the bandpass signal.

a) The modulation index "u" is calculated by dividing the peak amplitude of the message signal by the peak amplitude of the carrier signal. In this case, the message signal is m(t) = 2 · cos(104nt), and the carrier signal is c(t) = 5 cos(10,000ft). Therefore, the modulation index "u" is 2/5.

b) The bandwidth of the baseband signal in an AM system is equal to twice the frequency of the message signal. Here, the message signal has a frequency of 104n. Hence, the baseband signal bandwidth is 2 * 104n.

c) The bandwidth of the bandpass signal in an AM system is equal to twice the frequency of the carrier signal. In this case, the carrier signal has a frequency of 10,000f. Therefore, the bandpass signal bandwidth is 2 * 10,000f.

d) The lower cutoff frequency (FL), upper cutoff frequency (FH), and center frequency (Fc) for the bandpass signal depend on the carrier frequency and the bandwidth of the bandpass signal. The lower cutoff frequency (FL) is given by Fc - (bandwidth/2), the upper cutoff frequency (FH) is given by Fc + (bandwidth/2), and the center frequency (Fc) is the carrier frequency.

In conclusion, a) the modulation index "u" is 2/5, b) the bandwidth of the baseband signal is 2 * 104n, c) the bandwidth of the bandpass signal is 2 * 10,000f, and d) the FL, FH, and Fc for the bandpass signal depend on the carrier frequency and the bandwidth of the bandpass signal.

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.

Consider a vapor compression system used for cooling a home and rejecting energy to the outdoor ambient. What will happen to the cooling COP as the temperature difference between the indoor air and the ambient air decreases

Answers

In a vapor compression system used for cooling a home and rejecting energy to the outdoor ambient, the cooling COP (Coefficient of Performance) will decrease as the temperature difference between the indoor air and the ambient air decreases.

The cooling COP is a measure of the cooling efficiency of the system, which is defined as the ratio of the amount of cooling provided to the amount of energy consumed by the compressor. When the temperature difference between the indoor air and the ambient air decreases, the compressor has to work harder to remove the same amount of heat from the indoor air. This results in a decrease in the cooling efficiency of the system and hence a decrease in the cooling COP.
For example, if the outdoor ambient temperature is very high and the indoor air temperature is much lower, the cooling COP will be high

Verify by substitution that the given functions form a basis. Solve the given initial value problem (Show details of your work): a) y" – 25y = 0, cos 5x, sin 5x, y(0)=0.8, y'(0)=-6.5 b) y

Answers

The solution to the initial value problem is y(x) = 0.8 × cos 5x - 1.3 × sin 5x

How to solve initial value?

To verify if the given functions form a basis, check if they are linearly independent and span the entire solution space. Start with the given functions:

a) Functions: cos 5x, sin 5x

To check linear independence, take a linear combination of the functions and set it equal to zero:

A × cos 5x + B × sin 5x = 0

To show that the only solution is A = 0 and B = 0, differentiate both sides:

-5A × sin 5x + 5B × cos 5x = 0

Now, set x = 0 to simplify the equation:

-5A × sin 0 + 5B × cos 0 = 0

This simplifies to:

5B = 0

Since sin 0 = 0 and cos 0 = 1, the equation becomes:

5B = 0

From this equation, B must equal 0. Plugging this value back into the original linear combination equation:

A × cos 5x + 0 × sin 5x = 0

This simplifies to:

A × cos 5x = 0

Since cos 5x ≠ 0 for all x, conclude that A must also equal 0. Therefore, the functions cos 5x and sin 5x are linearly independent.

Now, to check if they span the solution space, determine if any solution to the differential equation y" - 25y = 0 can be expressed as a linear combination of the given functions. In this case, the general solution to the differential equation is:

y(x) = C1 × cos 5x + C2 × sin 5x

where C1 and C2 are constants.

Since the given functions cos 5x and sin 5x are part of the general solution, they span the solution space.

Therefore, the functions cos 5x and sin 5x form a basis.

Now, move on to solving the initial value problem:

a) y" - 25y = 0, cos 5x, sin 5x, y(0) = 0.8, y'(0) = -6.5

The general solution to the differential equation is:

y(x) = C1 × cos 5x + C2 × sin 5x

To solve for the constants C1 and C2, use the initial conditions.

Given: y(0) = 0.8, y'(0) = -6.5

Plugging in the values:

y(0) = C1 × cos(0) + C2 × sin(0) = C1

C1 = 0.8

Now, differentiate the general solution to find y'(x):

y'(x) = -5C1 × sin 5x + 5C2 × cos 5x

Plugging in x = 0:

y'(0) = -5C1 × sin(0) + 5C2 × cos(0) = 5C2

Given: y'(0) = -6.5

5C2 = -6.5

C2 = -1.3

Therefore, the solution to the initial value problem is:

y(x) = 0.8 × cos 5x - 1.3 × sin 5x

A moist rock mass is characterized by the following parameters: joint water pressure is nill; point load index is 3MPa; Joint spacing is 0.5m; and RQD is 55%; Joint condition is open joints filled with 5mm gouge. Classify the rock mass according to RMR method.

Answers

The RMR value is 413.15, which indicates that the rock mass is of excellent quality.

What is RMR method?

The most important geologic criteria are combined by RMR, which depicts them as a single, comprehensive indicator of rock mass quality.

Based on the given parameters, we can use the Rock Mass Rating (RMR) method to classify the rock mass.

The RMR value is given by the formula:

RMR = 70Q + 10G + 5F + 8L + 7S - 3W

Using the given parameters, we can calculate the RMR value as follows:

Q = 10 x \((RQD/10)^{1/2\) x (Jn + Ja + Jw + Jr + Jsr)

Where Jn, Ja, Jw, Jr, and Jsr are the joint sets orientations, number, water pressure, roughness, and spacing rating, respectively.

Since we do not have information about the joint orientations and roughness, we can assume that they have a neutral effect on the RMR value, which means that Jn=Ja=Jr=1 and Jw=Jsr=0.5.

Therefore,

Q = 10 x\((55/10)^{1/2\) x (1 + 1 + 0.5 + 1 + 0.5) = 57.45

G = 0 (since joint water pressure is nil)

F = 5 (since the joint condition is open joints filled with gouge)

L = 8 - 2.6 x log10(0.5) = 5.44

S = 7 (since the joint condition is filled with 5mm gouge)

W = 0 (since joint water pressure is nil)

Thus, RMR = 7057.45 + 100 + 55 + 85.44 + 77 - 30 = 413.15
