4) (6pts) using two 74x163 counters, design a counter with counting sequence 0, 128, 129,..., 254, 255, 0, 128, 129, ... , 254, 255. logic 0 and 1 are available.

Answers

Answer 1

To design a counter with the given counting sequence, we can use two 74x163 counters and connect them in a specific way. Firstly, we will use one counter to count from 0 to 127, and the other counter to count from 0 to 255.


For the first counter, we can connect the CP (clock pulse) inputs of both counters together and feed them with the clock signal.

The MR (master reset) input of this counter will be connected to logic 1, and the ENT (enable parallel load) input will be connected to logic 0. We will also connect the QA-QD (outputs) of this counter to the A-B (parallel load) inputs of the second counter.For the second counter, we can connect its CP input to the QA output of the first counter, which will cause it to count only when the first counter reaches 128. The MR input of this counter will be connected to logic 1, and the ENT input will be connected to logic 0. Finally, we will connect the QA-QD outputs of this counter to the output terminals of the overall counter.By combining the outputs of the two counters in this way, we will get the desired counting sequence of 0, 128, 129, ..., 254, 255, 0, 128, 129, ..., 254, 255. The counter will also automatically reset to 0 when it reaches 255, which is the maximum count value of an 8-bit counter.

A company is currently paying its employees $0.38 per mile to drive their own cars on company business. The company is considering supplying employees with cars, which would involve purchasing at $25,000 with an estimated three-year life, a net salvage value of $8,000, taxes and insurance at a cost of $900 per year, and operating and maintenance expenses of $0.22 per mile. If the interest rate is 10% and the company anticipates an employee’s annual travel to be 22,000 miles, what is the equivalent cost per mile (neglecting income taxes)?

Answers

The equivalent cost per mile is mathematically given as

Equivalent kilometer =  0.61

What is Distance?

Distance is a measure of the distance between two places. Depending on context, the term "distance" might refer to a precise measurement or an approximation based on other factors. |AB| can be used to represent the distance between two points.

What is an Equivalent cost per mile?

Generally, the equation for Equivalent annual cost  is  mathematically given as

EAC= $ 25,000 ( A/P, 10% , 3 years ) + $ 900 + $ 0.22 * 22,000 - $ 8000 ( A/F , 10% , 3 years)

Therefore

EAC= $ 25,000 * 0.402115 + $ 5740 - $ 8000 * 0.302115

EAC= $ 13,375.955

In conclusion, the Equivalent cost per kilometer

Equivalent kilometer [tex]=\frac{ 13,375.955}{22,000}[/tex]

Equivalent kilometer =  0.61

7.35 and 7.36 For the beam and loading shown, (a) draw the shear and bending-moment diagrams, (b) determine the maximum absolute values of the shear and bending moment.

Answers

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m

How to draw Shear Force and Bending Moment Diagram?

A) We can see the beam loaded in the first image attached.

For the shear diagram, let us calculate the shear from point load to point load.

From A to C, summing vertical to zero gives; ∑fy = 0: -20 - V = 0

V = -20 KN

From C to D, summing vertical to zero gives; ∑fy = 0: -20 + 48 - V = 0

V = 28 KN

From D to E, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - V = 0

V = 8 KN

From E to B, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - 20 - V = 0

V = -12 KN

For the bending moment diagram, let us calculate the bending moment from point load to point load.

At point A, the bending moment would be zero. Thus, M_A = 0 KN.m

At point C, taking moment about point C and equating to zero gives;

M_C = 0. Thus; 20(0.225) + M = 0

M = -4.5 KN.m

At point D, taking moment about point D and equating to zero gives;

M_D = 0. Thus; 20(0.525) - 48(0.3) + M = 0

M = 3.9 KN.m

At point E, taking moment about point E and equating to zero gives;

M_D = 0. Thus; 20(0.75) - 48(0.525) + 20(0.225) + M = 0

M = 5.7 KN.m

At point B, taking moment about point E and equating to zero gives;

M_E = 0. Thus; 20(1.05) - 48(0.825) + 20(0.525) + (20 * 0.3) + M = 0

M = 2.1 KN.m

2) From the attached diagrams, we can deduce that;

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.

What is travel speed?

The travel speed of the welding flame or gun across the workpiece is simply measured in millimeters per minute.

Travel speed, along with voltage and amperage, is one of three factors in arc welding that affect the amount of heat input.

What is the calculation that justifies the above answer is?

We are given the following:


Melting temperature = 1650 K

k = (3.33 * 10⁻⁶) * (1,650)²

k = 9.066 J/mm^3

The formula for velocity here is given as:

V = f1 * f2 * Rh / (k*A)

V = 0.9 * 0.6 * 3000 / (9.066*25)

V = 7.147 mm/s

Answers

The time at which the acceleration is zero is given as 4.66 seconds

How to solve for the time

First we have to solve for the velocity. To do this, we would have to take the derivative.

[tex]s = e^-0.5t (3 t - 2)[/tex]

Then velocity =

[tex]ds/dt = e^-0.5t (4 - 1.5 t)[/tex]

The acceleration can be gotten by finding the second derivative

[tex]a = dv/dt = e^-0.5t (.75 t - 3.5)[/tex]

To find t at acceleration = 0

Explanation:

We can the formula:

where

ω ⇒ angular speed (24 rad/s),

T ⇒ time period (? s),

and solve for T to find the time it takes for the wheel to complete one revolution.

⇒  [tex]24 = \frac{2 \pi}{T}[/tex]

⇒  [tex]T = \bf \frac{2 \pi}{24}[/tex]  s

This means it takes [tex]\bf \frac{2 \pi}{24}[/tex] seconds for the wheel to complete one revolution.

Now, using the unitary method,

In [tex]\frac{2 \pi}{24}[/tex] seconds          ⇒    1 revolution completed

In 1 second              ⇒    1 ÷ [tex]\frac{2 \pi}{24}[/tex]   =  [tex]\frac{24}{2 \pi}[/tex]  revolutions completed

In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.

Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.

The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

(b) Repeat part (a), but this time compute Xk+1 = (1/4) A-1Xk, for k = 0,1,...,3, and compare the sequence wi!....Ma with the smallest eigenvalue of A. Connect your observations to your explanation in part (b) by relating the eigenvectors and eigenvalues of A-1 to those of A.
