1. Which datapath elements are accessed if "add" is executed? (choose from: instruction memory, register file, ALU, data memory)
2. What kind of hazards can be observed in the single-cycle processor if the processor has one united memory?

Answers

Answer 1

1. When an "add" operation is executed, the datapath elements accessed are the instruction memory, register file, and ALU (Arithmetic Logic Unit).

2. Single-cycle processors with a unified memory can exhibit both structural and data hazards. The execution of the "add" operation involves fetching the instruction from the instruction memory, reading the operands from the register file, and carrying out the addition operation in the ALU. The result is then written back into the register file. The data memory is not used in this operation, as it is typically involved when dealing with load and store instructions. In a single-cycle processor with one unified memory, hazards can occur. A structural hazard may arise when the processor attempts to perform a fetch and a memory operation simultaneously, as these both require access to the same memory unit. Data hazards occur when instructions that depend on each other are executed in succession. For example, if one instruction is writing a result to a register while the next instruction reads from the same register, it might read the old value before the new value has been written, leading to incorrect computations.

Determine the length of welds required to transmit a load 54.5 KN between 12.7mm. thick plates, when the plates are to be joined by 1) Two parallel fillet welds. 2) Two transverse fillet welds.

Answers

For the parallel fillet weld, the length required is 24.52mm and for transverse fillet welds, the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.

What is the length to transmit the load

The length of weld required to transmit a load between two plates depends on the type of weld used and the strength of the material being welded. For the given scenario:

Two parallel fillet welds:

The length of each fillet weld required can be calculated using the following formula:

L = (2 x F x P) / (0.7 x T)

where L is the length of each fillet weld, F is the applied force (54.5 KN), P is the perimeter of the weld (2 x length of the joint), T is the thickness of the plate (12.7 mm), and 0.7 is a constant. Substituting the values, we get:

L = (2 x 54.5 x 2) / (0.7 x 12.7) = 24.52 mm

Therefore, the length of each fillet weld required is 24.52 mm.

Two transverse fillet welds:

The length of each fillet weld required in this case can be calculated using the same formula as above, but with the perimeter of the weld being the sum of the lengths of the two sides being welded. Since the two fillet welds are transverse, their lengths will be different. Assuming one fillet weld is longer than the other, we can calculate their lengths as follows:

L1 = (F x P1) / (0.7 x T)

L2 = (F x P2) / (0.7 x T)

where L1 and L2 are the lengths of the two fillet welds, P1 and P2 are the perimeters of the two sides being welded, and all other variables are the same as before. We can assume that the longer fillet weld is on the side with the higher applied force, so we have:

P1 = 2 x length of joint

P2 = length of joint

Substituting the values, we get:

L1 = (54.5 x 2 x 2) / (0.7 x 12.7) = 24.39 mm

L2 = (54.5 x 1) / (0.7 x 12.7) = 6.13 mm

Therefore, the length of the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.

This is especially important when skydiving in areas with high winds that could otherwise cause the skydiver to be thrown off course.

determine the maximum magnitude p of the loads the beam can support if the average shear stress in each pin is not to exceed 80 mpa. all pins are in double shear, and each has a diameter of 18 mm.

Answers

The maximum magnitude of the load the beam can support is 547.16 N.

The maximum magnitude of the load the beam can support can be calculated using the formula:

p = 2 * τ * π * d^2 / (4 * n)

where:

τ is the maximum allowable shear stress (80 MPa)

d is the diameter of the pins (18 mm)

n is the number of pins in double shear

Converting the diameter to meters, we have:

d = 18 * 10^-3 m

Let's assume n=2 pins in double shear. Then,

p = 2 * 80 * 10^6 * π * (18 * 10^-3)^2 / (4 * 2)

p = 547.16 N

Answers

Both technicians are correct. A pressure check valve is designed to prevent the backflow of fluid in a hydraulic system, thereby maintaining system pressure.

Technician A is correct in stating that the check valve should hold system pressure for at least five minutes after the pump is shut off. This is important because it allows the hydraulic system to maintain pressure even when the pump is not operating.
Technician B is also correct in saying that a defective check valve could cause long cranking time. This is because a defective check valve can cause the hydraulic system to lose pressure, which can result in a longer cranking time for the pump to build up the required pressure again.
In summary, both technicians are correct in their statements about the pressure check valve. It is important to ensure that the check valve is functioning properly to prevent any issues with system pressure and cranking time.

How to generate T given a random number generator of a random variable X uniformly distributed over the interval (0,1)? Present a formal mathematical proof that your algorithm for generating T is correct.

Answers

The algorithm provided correctly generates T using a random number generator and the exponential distribution formula. It is mathematically proven and ensures that Y is uniformly distributed over the interval (0, 1) when X is uniformly distributed over the same interval.

To generate T given a random number generator of a random variable X uniformly distributed over the interval (0,1), follow the steps below:

Algorithm to generate T

Generate two random numbers X and Y from the interval (0, 1) using the random number generator.Compute T as T= -ln(1 - Y)/λ.

Here, λ is the rate parameter of the exponential distribution represented by T.This algorithm for generating T is correct and can be proved mathematically as follows:

Proof:

First, we will find the cumulative distribution function (CDF) of T. We know that T is exponentially distributed with parameter λ. Hence, the CDF of T is given by: F(t) = P(T ≤ t) = ∫0t λe^(-λt) dt = 1 - e^(-λt)

Now, let's find the inverse of the CDF. Since 0 < X < 1, we have: P(T ≤ t) = X

Therefore, we have:1 - e^(-λt) = X e^(-λt) = 1 - X -λt = ln(1 - X)

Thus, the inverse of the CDF is given by:T = - ln(1 - X)/λ

Now, we need to show that Y is uniformly distributed over the interval (0, 1) if X is uniformly distributed over the interval (0, 1).

Since X is uniformly distributed over the interval (0, 1), its CDF is given by: F(x) = x for 0 ≤ x ≤ 1

Let's find the CDF of Y. Since Y = F(T), we have: P(Y ≤ y) = P(F(T) ≤ y) = P(T ≤ F^-1(y))= F(F^-1(y))= y

Thus, the CDF of Y is: F(y) = y for 0 ≤ y ≤ 1

Hence, Y is uniformly distributed over the interval (0, 1) if X is uniformly distributed over the interval (0, 1).

A rocket is shot straight up from the earth with a net acceleration (= acceleration by the rocket engine - gravitational pullback) of 7m/sec during the initial stage of flight until the engine cut out at t = 10 sec. How high will it go, air resistance neglected?

Answers

Answer:

599.7 m

approximately 600 m

Explanation:

initial speed of the rocket = 0

net acceleration upwards = 7 m/s^2

the engine cuts out 10 sec after take off

maximum height reached = ?

we neglect air resistance

To get the velocity of the rocket at the point where the engine cuts off, we use the equation

v = u + at

where

v is the velocity at this point where the engine stops = ?

u is the initial velocity of the rocket from rest = 0 m/s

a is the net acceleration upwards = 7 m/s^2

t is the time the engine runs = 10 s

substituting, we have

v = 0 + (7 x 10)

v = 70 m/s

to get the distance from the ground to this point, we use the equation

\(v^{2}\) = \(u^{2}\) + 2as

where

v is the final velocity at the the height where the engine is cut out = 70 m/s

u is the initial speed at the ground = 0 m/s

a is the net acceleration on the rocket = 7 m/s^2

s is the distance from the ground to this point

substituting, we have

\(70^{2}\) = \(0^{2}\) + 2(7 x s)

4900 = 14s

s = 4900/14 = 350 m

After this point when the engine cuts out, the rocket experiences an acceleration proportional to the acceleration due to gravity 9.81 m/s^2 downwards, and slows down gradually before coming to a stop at the maximum height.

To get this height, we use the equation

\(v^{2}\) = \(u^{2}\) - 2gs   (the negative sign is due to the downward direction of the acceleration g)

where

v is the final velocity at the maximum height = 0 m/s (it comes to a stop)

u is the speed at the instance that the engine is cut out = 70 m/s

g is the acceleration due to gravity = 9.81 m/s^2

s is the distance from this point to the maximum height

substituting values, we have

\(0^{2}\) = \(70^{2}\) - 2(9.81 x s)

0 = 4900 - 19.62s

4900 = 19.62s

s = 4900/19.62 = 249.7 m

The maximum height that will be reached = 350 m + 249.7 m = 599.7 m

approximately 600 m

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.

One man had faith, accompanied by works, and in Dr. Schliemann the science of classical antiquity found its Columbus. Armed with the spade, he brought to light from beneath the mounds of the ages a real Troy; at Tiryns and Mycenae he laid bare the palace and the tombs and treasures of Homeric Kings. A new world opened to investigation, and the discoveries of its first explorer were followed up successfully by Dr. Tsountas and others on Greek soil. The eyes of observers were opened, and the traces of this prehistoric civilization began to make their appearance far beyond the limits of Greece itself.Sir Arthur Evans, archaeologist,as quoted in The DiscoverersWhat does wrapped in an impenetrable mist mean?a.undiscoveredc.never dreamed ofb.foggyd.clearly seenPlease select the best answer from the choices providedABCD When we go along with the crowd to avoid rejection, or to gain their approval, we are conforming because of___________.
