Answers
Equivalent Circuit:When analyzing circuits, it's sometimes helpful to simplify them into a more manageable form. Thevenin equivalent circuits are one way to accomplish this.
The Thevenin equivalent circuit replaces the original circuit with a simpler one that includes a single voltage source and a single series resistor.In order to find the Thevenin equivalent of the given circuit, follow these steps:1. Remove the component terminals that are connected to a-b2. Calculate the equivalent resistance of the circuit when viewed from terminals a-b3. Calculate the open-circuit voltage between a and b when no current is flowing through the circuit4. Thevenize the circuit using the results of steps 2 and 3.
The given circuit can be redrawn in the following manner:Redrawn CircuitFirst, the equivalent resistance of the circuit will be determined. To do this, combine the three resistors in the circuit.R1 = 10 Ω, R2 = -j4 Ω, and R3 = 4 ΩR1 and R3 are in series, so they may be combined to give an equivalent resistance of 14 Ω.R2 is in parallel with the 14 Ω resistor, so the equivalent resistance between points a and b is:Req = 14 Ω || -j4 ΩReq = (14 * -j4)/(14 - j4)Req = 9.3043 + j3.7826 ΩUsing PSpice, the voltage between points a and b with no load current is measured to be:Voc = 6.2626 ∠17.139° V.
The Thevenin equivalent voltage and resistance are as follows:VTh = 6.2626 ∠17.139° VReq = 9.3043 + j3.7826 ΩUsing MATLAB to verify the answer:clc;clear all;close all;R1 = 10; R2 = -j*4; R3 = 4; w = 40/45; V = 8/0; jn = j*5; % Equivalent resistance Req = (R1 + R3)*R2/(R1 + R3 + R2); % Open-circuit voltage Voc = V*((R1 + R3)*jn)/(R1 + R3 + jn); % Thevenin voltage and resistance VTh = Voc; Req = Req; Voc, VTh, Req
Thus, the Thevenin equivalent circuit of the given circuit when viewed from terminals a-b is a voltage source of 6.2626∠17.139° V in series with a resistance of 9.3043 + j3.7826 Ω.

Using the simplified lifting model illustrated in the figure you can estimate the compressive loads in the lower back (L5/S1 joint). The figure shows two loads acting on the body: the weight of the upper body of the person (HAT = Head, Arms, Trunk) and a weight that is being lifted (OBJECT). The moment arms for these 2 loads are the distances from each force vector to th L5/S1 joint. Enter your student ID to get your personalized values for HAT weight (weight_HAT), OBJECT Weight (weight_OBJECT), HAT moment arm (mmt_arm_HAT), OBJECT moment arm (mmt_arm_OBJECT), Sacral Angle (ang_Sacral), and MUSCLE moment arm (mmt_arm_MUSCLE).

Answers
Thus external torque is -146.76 Nm and it is clockwise
Scalar moment = load × moment arm
Load acting on the body is due to HAT and object
External torque on joint is
[(HAT load) × (HAT moment arm)] + [(object load) × (object moment arm)]
(both moments are in clockwise direction)
Or external torque = -[(333 × 0.22) + (245 × 0.3)] = -146.76 Nm
Thus external torque is -146.76 Nm and it is clockwise.
This is so because the force and speed of the pistons' motion determine the torque. High levels of this torque force can be produced by the fastest cars at relatively low rpm. This enables speedy acceleration of the vehicle. The definition of torque is rF=rFsin(r). In other terms, torque is the cross product of the force vector and the distance vector, where 'a' is the angle between r and F. The distance vector represents the distance from the pivot point to the place where force is applied.

Explanation:
a rotor has a weight of 100 lb with a centroidal radius of gyration of 9 in. determine the moment of inertia about the center of gravity for the rotor.
Answers
To determine the moment of inertia about the center of gravity for the rotor, we can use the formula:
I = Mk²
Where I is the moment of inertia, M is the mass of the object, and k is the radius of gyration.
In this case, the rotor has a weight of 100 lb, which we can convert to mass using the formula:
M = W/g
Where W is the weight and g is the acceleration due to gravity (32.2 ft/s²). Therefore:
M = 100 lb / (32.2 ft/s²) = 3.11 slugs
The centroidal radius of gyration is given as 9 in, which we can convert to feet by dividing by 12:
k = 9 in / 12 = 0.75 ft
Now we can plug in the values to get:
I = Mk² = (3.11 slugs) x (0.75 ft)² = 1.65 slug-ft²
Therefore, the moment of inertia about the center of gravity for the rotor is 1.65 slug-ft².

The entrance to the pipe has minor loss coefficient 0.4 and the exit has minor loss coefficient of 1, both referenced to the velocity in the pipe. The water level of the upper tank is 4 m above the level of the lower tank, and the pipe is 5 m long. You will find the drainage volumetric flow rate. a) What is the relative roughness
Answers
Answer:
Relative roughness = 0.04
Explanation:
Given that:
Diameter = 5 cm
roughness = 2 mm
At inlet:
Minor coefficient loss \(k_{L1} = 0.4\)
At exit:
Minor coefficient loss \(k_{L2} = 1\)
Height h = 4m
Length = 5 m
To find the relative roughness:
Relative roughness is a term that is used to describe the set of irregularities that exist inside commercial pipes that transport fluids. The relative roughness can be evaluated by knowing the diameter of the pipe made with the absolute roughness in question. If we denote the absolute roughness as e and the diameter as D, the relative roughness is expressed as:
\(e_r = \dfrac{e}{D}\)
\(e_r = \dfrac{0.2 }{5}\)

A rain gutter is to be constructed from a metal sheet of width 3m by bending up one-third of the sheet on each side through an angle θ. How should θ be chosen so that the gutter will carry the maximum amount of water?.
Answers
The area of the gutter is therefore equal to the area of the rectangle plus the area of the triangles.
A = rectangle + 2 * triangle
= 10h + 2 * (1/2 hw)
Using trig work out h and w.
h = 10 sin ?
w = 10 cos ?
A = 10h + hw
= 100sin? + 100sin?cos?
Differentiate the expression (either use the product rule for sin? cos?, or write 100sin?cos? as 50sin2? using the double angle formula)
A = 100sin? + 50sin2?
dA/dt = 100cos? + 100cos2?
For A to be a max or min the derivative must equal zero
100cos? + 100cos2? = 0
cos? + cos2? = 0
Use the double angle formula to write cos2? as 2cos^2 ? - 1
cos? + 2cos^2 ? - 1 = 0
2cos^2 ? + cos? - 1 = 0
This quadratic factorizes:
(2cos? - 1)(cos? + 1) = 0
This means that
cos ? = 1/2 or cos ? = 1
giving:
? = pi/3 or ? = pi
Which means that to achieve the maximum area ? should be pi/3 = 60 degrees
You can check that this is the max by substituting in these values of theta and the two end points (theta = 0, theta = pi), and seeing that pi/3 gives the maximum.
The maximum area is therefore
A = 100sin? + 100sin?cos?
= 100sin(pi/3) + 100sin(pi/3)cos(pi/3)
= 100 sqrt(3) / 2 + 100 sqrt(3)/2 * 1/2
= 100 * 3/2 * sqrt(3) / 2

Answers
The largest unsigned integer that may be stored in 20 bits is 1,048,575. Option d) is correct.
In computing, unsigned integers are the set of integers, which do not contain the negative integers but the positive integers.
The unsigned integer is the group of positive integers, including zero. Unsigned integers have values ranging from zero to a maximum positive value that can be stored using a fixed number of bits.
To obtain the largest unsigned integer that may be stored in 20 bits, we need to follow these steps;
1. A bit is a binary digit, so it can have only two possible values, either 0 or 1.
2. If there are 20 bits in total, we need to multiply 1 by 2, 20 times, to get the number of combinations.
3. To calculate the highest number of combinations, subtract 1 from the total number of combinations. This is because 0 is one of the combinations, and we're counting only positive integers.
4. Finally, multiply the answer by 2^20, which is the highest decimal value we can have with 20 bits.
The formula to get the maximum unsigned integer is2^20 - 1 = 1,048,575
Therefore, the largest unsigned integer that may be stored in 20 bits is 1,048,575.

Chances of death or injury at low speeds when driver is unbelted are the same as those who are belted drivers. (False)
What happens when drivers are unbelted?Beginning with the "high speed road" state of the "road type" variable, it can be seen that the higher risk of fatality occurs when a driver is distracted, is not wearing a seat belt, and is operating a vehicle at a high speed, such as on a motorway or a comparable road. This would be one of the most dangerous scenarios in a traffic accident because 48.52% is the highest value in this study.
However, when a driver is not wearing a seatbelt, is distracted, and is travelling at a low speed, there is only a 25% chance that they will cause a fatality or serious injury. This suggests that a lower driving speed will result in a slower impact speed, which can lower the risk of suffering a serious injury.
