Here the explanation:
The actual pressure that a fabric undergoes is primarily based totally on its extrusion ratio, which affects how a good deal of painting is achieved at the billet. Pressure depends on this quantity of paintings.The pressure because of friction is depending on the die angles; because the attitude increases, the paintings required increases, affecting the extrusion strain. As the extrusion speed increases, the extrusion pressure ought to additionally boom because of the friction forces of the die.As billet temperature increases, strain decreases. The equation p = Kc*ln(R) (that's used to estimate the pressure in warm extrusion) demonstrates this, in which Kc represents a fabric regular this is depending on temperature. As temperature increases, the regular decreases demonstrating an inverse dating among pressure and temperature.The perpendicular force per unit surface, or the stress at a point within a confined fluid is called as pressure.

assuming complementary inputs are available, the minimum number of transistors needed to realize a two input xor gate is:
Assuming complementary inputs are available, the minimum number of transistors needed to realize a two input xor gate is 4.
If two inputs work well together in the production process, they are said to be complements. Since the inputs are used in fixed proportions, if the price of one input lowers, more of it will be sought after, increasing the demand for the other input.
In this study, a model of anticompetitive exclusive contracts with complimentary inputs is built. A downstream company converts a variety of complementary inputs into finished goods. When complementary input providers hold a dominant position in a specific input market, upstream competition price within that market benefits both the downstream firm and the complementary inputs providers by driving up complementary input prices.
Thus, even when entry that is socially optimal is permitted, the downstream firm is unable to generate higher profits. Therefore, even in the absence of scale economies, downstream competition, and relationship-specific investment, the inefficient incumbent provider can prevent socially efficient entrance by employing exclusive contracts.

(b)0-75 volt, 20000 ohms/volt meter
(c)voltmeter with an input impedance of 20 megaohms
Answer:
(a) -55.6%, -31.25 V
(b) -11.1%, -6.25 V
(c) -0.93%, -0.52 V
Explanation:
The open-circuit voltage is (75V)(750/(250+750)) = 56.25 V.
The circuit to which the meter is connected has a Thevenin equivalent impedance of 1/(1/250 +1/750) = 187.5 kΩ. So, the relative error for a given meter impedance of R (in kΩ) is ...
(R/(R +187.5) -1) × 100% = -187.5/(R +187.5) × 100%
(a) For a meter impedance of (1 kΩ/V)×150V = 150 kΩ, the error is ...
-187.5/(150 +187.5) × 100% ≈ -55.6%
The voltage error is (56.25 V)(-55.6%) = -31.25 V.
__
(b) For a meter impedance of (20 kΩ/V)×75V = 1500 kΩ, the error is ...
-187.5/(1500+187.5) × 100% ≈ -11.1%
The voltage error is (56.25 V)(-5.88%) = -6.25 V.
__
(c) For a meter impedance of 20,000 kΩ, the error is ...
-187.5/(20000+187.5) × 100% ≈ -0.93%
The voltage error is (56.25 V)(-0.93%) = -0.52 V.

leaks from the ____________ can result in coolant misting out of the vents or coolant dripping from the same drain hole used by the ac evaporator.
Leaks from the heater core can result in coolant misting out of the vents or coolant dripping from the same drain hole used by the AC evaporator.
The heater core is a component in a vehicle's heating system that helps provide warm air to the interior of the vehicle. It is typically located behind the dashboard and is connected to the engine's cooling system.
When there is a leak in the heater core, coolant (a mixture of antifreeze and water) can escape from the core. This coolant can then find its way into the ventilation system, where it can be forced out of the vents and create a misting effect. This misting of coolant can be noticeable as a fine spray or droplets coming out of the vents when the heating system is turned on.
Additionally, the HVAC (Heating, Ventilation, and Air Conditioning) system in many vehicles shares some components with the AC (Air Conditioning) system, including the drain hole used by the AC evaporator to remove condensation. If there is a heater core leak, coolant can also drip from the same drain hole used by the AC evaporator, leading to coolant dripping onto the ground beneath the vehicle.
These coolant leaks from the heater core can be problematic as they can cause a loss of coolant from the engine cooling system, which can lead to overheating of the engine if not addressed. It is important to have any coolant leaks diagnosed and repaired by a qualified mechanic to ensure the proper functioning of the vehicle's heating and cooling systems and to prevent potential engine damage.

2. --a 4
--b 4
3. --a 2
--b 30 rpm
--c 75 ft.·lb.
4. --a Second class lever
--b 50 lbs.
Explanation:
The Actual Mechanical Advantage, AMA, is given as follows;
\(AMA = \dfrac{F_R}{F_E}\)
Where;
\(F_R\) = The resistance force magnitude
\(F_E\) = The effort force magnitude
1. a. We have;
\(F_R\) = 10 lb.
\(F_E\) = 100 lb.
\(AMA = \dfrac{100 \ lb}{10 \ lb} = 10\)
b. \(Mechanical \ advantage, \ M.A. = \dfrac{Distance \ moved \ by \ load}{Distance \ moved \ by \ effort}\)
The diameter of the axle, d = 2 in.
Let 'D' represent the diameter of the wheel, we have;
The distance moved by the axle, c = π·d
The distance moved by the load, C = π·D
\(M.A. = 10 = \dfrac{\pi \cdot D}{\pi \times 2}\)
∴ 2 × 10 = D
D = 20 in.
The required wheel diameter to overcome the resistance force, D = 100 in.
2. --a The mass of the participants, m = 200 lb.
The depth of the ground of the participants = 20 feet
The effort force = 50 lb
Actual Mechanical Advantage, AMA = 200 lb./(50 lb.) = 4
--b. The number of strands of pulley needed ≈ The mechanical advantage = 4
3. The number of gears on Gear A = 10 teeth
The number of gears on Gear B = 8 teeth
The number of gears on Gear C = 20 teeth
-a. Given that the driver gear = Gear A
The output gear = Gear C
\(The \ gear \ ratio = \dfrac{The \ number \ of \ teeth \ on \ the \ driven \ gear}{The \ number \ of \ teeth \ on \ the \ driver \ gear}\)
The driver gear = The input gear
Therefore, we have;
\(The \ gear \ ratio = \dfrac{20 \ teeth}{10 \ teeth} = 2\)
The gear ratio = 2
-b \(The \ gear \ ratio = \dfrac{The \ driver \ gear\ speed}{The \ driven \ gear\ speed}\)
Therefore, we have;
\(The \ gear \ ratio = 2 = \dfrac{60 \ rpm}{Gear\ C \, speed}\)
\(Gear\ C \, speed = \dfrac{60 \ rpm}{2} = 30 \ rpm\)
-c The output (driven) gear torque at Gear C = 150 ft.·lb.
\(The \ gear \ ratio = \dfrac{Driven \ gear \ torque}{Driver \ gear \ torque}\)
Therefore;
\(2 = \dfrac{150 \ ft \cdot lb}{Driver \ gear \ torque}\)
\(Driver \ gear \ torque = \dfrac{150 \ ft \cdot lb}{2} = 75 \ ft \cdot lb\)
The input (driver) torque at Gear A = 75 ft·lb
4. -a Given that the load is between the effort and the fulcrum, we have;
The type of lever is a second class lever
-b The distance between the load and the fulcrum = 4 feet
The distance between the effort and the fulcrum = 8 feet

a 2 m wide square foundation is placed at a depth of 1.5 m, in a very thick homogeneous sand deposit where qc 5 10 mn/m2 and g 5 18.5 kn/m3. the stress level at the foun- dation is 140 kn/m2. estimate the settlement in 25 years, using the method of schmertmann et al. [eq. (9.30)]. how 9.17 much of this settlement is due to creep?
To estimate the settlement in 25 years using the method of Schmertmann et al., we can use the equation (9.30) provided. However, since you mentioned the term "creep," we need to consider the creep settlement as well.
The equation (9.30) for estimating the settlement is:
Δs = (2.5 * Δσvc) * (log10(t + 0.05) - log10(t0 + 0.05))
Where:
Δs is the settlement in meters
Δσvc is the increase in vertical effective stress in kN/m²
t is the time in years
t0 is the reference time (initial time) in years
First, let's calculate the increase in vertical effective stress (Δσvc) using the equation:
Δσvc = qc * Bq * Nγ
Where:
qc is the average cone resistance in MN/m² (converted from kN/m² by dividing by 1000)
Bq is the width of the foundation in meters
Nγ is the correction factor for the foundation width
Given that qc = 10 MN/m², Bq = 2 m, and Nγ = 0.5 (for a square foundation), we can substitute these values into the equation:
Δσvc = (10 MN/m²) * (2 m) * (0.5) = 10 MN/m²
Now, let's calculate the settlement (Δs) at 25 years using the equation (9.30):
Δs = (2.5 * 10 MN/m²) * (log10(25 + 0.05) - log10(t0 + 0.05))
Since the reference time (t0) is not mentioned, we'll assume it to be the current time, which is 0 years. Substituting the values into the equation:
Δs = (2.5 * 10 MN/m²) * (log10(25 + 0.05) - log10(0 + 0.05))
Simplifying the equation, we get:
Δs = 2.5 * 10 MN/m² * (log10(25.05) - log10(0.05))
Now, to calculate the creep settlement, we need more information such as the rate of creep. Without that information, we cannot determine the amount of settlement due to creep.

The nutritional labels on food products typically tell you how many calories of digestible energy are in one serving of food, where "digestible" means that the energy stored in the chemical bonds of the molecules comprising the food can be extracted by your body. (Water for example has energy, but that energy is not chemically accessible via digestion.) To simplify understanding for typical consumers, the "calories" reported on nutritional labels actually represent kilocalories: a 170 calorie can of beer actually contains 170,000 calories of digestible energy.
i) If a student foolishly decides to binge drink 21 beers on their 21t birthday, how many gallons of water could they have heated from room temperature (24 °C) to boiling (100 C) using an equivalent amount of digestible energy in the beer? Recall that one gallon of water is roughly 8 pounds.
ii) What is this energy equivalent to in BTU? A "BTU" or British Thermal Unit is also a unit of energy, defined as the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit
iii) If you had purchased an equivalent amount of electrical energy in kW-hr from the utility company, how much would you have to pay? Is this cheaper than buying beer?
A "calorie" is a unit of energy that is defined as the usually inform you of the number of calories of digestible energy present in one serving of food. 21 beers times 17 calories per beer equals 357 calories.
What is "calorie"?Calories are units of energy that a food or drink provides. You can usually find calorie counts listed on food items, and wearables like the best fitness trackers allow you monitor how many calories you're burning by doing different activities. Certain foods, such as fatty, fried, or processed foods, tend to have more calories. Other foods, such as fresh fruit and vegetables, tend to have fewer calories. However, some healthy fruits and vegetables can be high in calories, while low-calorie foods, such as diet soda, don’t provide any nutritional value. We need calories to give us enough energy to move around, stay warm, grow, work, think, and play. Even our blood circulation and digestion need the energy gained from calories in order to function well.To learn more about blood circulation refer to:

A particulate monitor has a power supply consisting of two batteries in parallel. Either battery is adequate to operate the monitor. However, since the failure of one battery places an added strain on the other, the conditional probability that the second battery will fail, given the failure of the first, is greater than the probability that the first will fail. On the basis of testing it is known that 7% of the monitors in question will have at least one battery failed by the end of their design life, whereas in 1% of the monitors both batteries will fail during the design life.
(a) Calculate the battery failure probability under normal operating conditions.
(b) Calculate the conditional probability that the battery will fail, given that the other has failed.

Explanation:
What happens when EPU output exceeds 32.5 volts
Answer:
In general, exceeding the rated voltage output of a power supply or electrical system could cause damage to the components being powered by that system. In some cases, this could result in the components malfunctioning or becoming permanently damaged, potentially leading to system failure. Additionally, exceeding the rated voltage of a system could cause electrical arcing or fires, which could be dangerous or catastrophic depending on the system and the environment it is operating in. Therefore, it is generally important to ensure that electrical systems are designed to operate within their rated voltage ranges to prevent damage and ensure safety.

The turbine develops 150 kW of power, which is transmitted to the gears such that C receives 70% and D receives 30%. Determine the angle of twist of end E of the shaft relative to B . Express your answer using three significant figures.
The angle of twist of end E of the shaft relative to B is 0.052°.
That the turbine develops 150 kW of power, which is transmitted to the gears such that C receives 70% and D receives 30%.
To determine the angle of twist of end E of the shaft relative to B, we have to use the following formula:
Torsional Stiffness (K) = [T/J] × L
Here,T is the applied torque
J is the polar moment of inertia of the shaft
L is the length of the shaft
Torsional angle of twist (θ) = TL / KJ
where,θ = angle of twist
T = applied torque
L = length of the shaft
K = torsional stiffness of the shaft
J = polar moment of inertia of the shaft
Now, let's find out the applied torque at point B.
Torque transmitted to point C = 70/100 × 150 = 105 kW
Torque transmitted to point D = 30/100 × 150 = 45 kW
Now, torque at point B, TB = TC + TD= 105 + 45= 150 kW
Let's calculate the polar moment of inertia J for the shaft.
From the formula, J = π/32 (D⁴ - d⁴)
where, D is the diameter of the outer shaft, d is the diameter of the inner shaft.
For the given shaft, outer diameter D = 0.2 m and inner diameter d = 0.15 mJ = π/32 (0.2⁴ - 0.15⁴) = 1.1798 × 10⁻⁴ m⁴
Now, we can find the torsional stiffness, K as K = [T/J] × L = [(150 × 10³)/(1.1798 × 10⁻⁴)] × 3= 3.774 × 10¹⁰ Nm/rad
Therefore, torsional angle of twist, θ = TL/KJ= (150 × 10³ × 3) / (3.774 × 10¹⁰ × 1.1798 × 10⁻⁴)= 0.0009 rad = 0.0518°
The angle of twist of end E of the shaft relative to B is 0.052°.
