Answer:

The above three conditions are commonly referred to as the equations of equilibrium for planar structures. ∑ Fx and ∑ Fy are the summation of the x and y components of all the forces acting on the structure, and ∑ Mz is the summation of the couple moments and the moments of all the forces about an axis z, perpendicular to the plane xy of the action of the forces.

Explanation:

The deceleration required to comply with the speed limit before being caught by the camera is 6.094 meters per square second.

Let assume that the motor car decelerates at constant rate. Given the initial and final speeds (\(v_{o}\), \(v\)), in meters per second, and travelled distance (\(s\)), in meters, the deceleration (\(a\)), in meters per square second, is determined by this formula:

\(a = \frac{v^{2}-v_{o}^{2}}{2\cdot s}\)

If we know that \(v_{o} = 25\,\frac{m}{s}\), \(v = 40\,\frac{m}{s}\) and \(s = 80\,m\), then the deceleration required to comply with the speed limit is:

\(a = \frac{\left(25\,\frac{m}{s} \right)^{2}-\left(40\,\frac{m}{s} \right)^{2}}{2\cdot (80\,m)}\)

\(a = -6.094\,\frac{m}{s^{2}}\)

The deceleration required to comply with the speed limit before being caught by the camera is 6.094 meters per square second.

Explanation:

Since the rollers are identical and the surfaces are smooth, the reaction forces at points A and C must be equal and vertical.

Let's call this force R. At point B, the reaction force is perpendicular to the inclined plane, so we can use trigonometry to find its magnitude.

Let's call this force T. Using the forces in the vertical direction, we can write: 2R + T = 2Q Using the forces in the horizontal direction

we can write: T = R tanθ where θ is the angle of inclination of the plane. Substituting the second equation into the first, we get: 2R + R tanθ = 2Q Simplifying: R (2 + tanθ) = 2Q R = 2Q / (2 + tanθ)

Plugging in the values: R = 2(100N) / (2 + tanθ) We can use trigonometry to find the value of tanθ: tanθ = opposite / adjacent = BC / AB

Since the rollers are identical, BC = AB, so: tanθ = AB / AB = 1 Therefore, R = 2(100N) / (2 + 1) = 50N and T = R tanθ = 50N * 1 = 50N

So the reaction forces at points A and C are both equal to 50N and vertical, while the reaction force at point B is equal to 50N and perpendicular to the inclined plane.

The Analytic Hierarchy Process (AHP) can be used to make a decision when selecting a car by considering various criteria and alternatives. AHP provides a structured approach for evaluating and prioritizing different factors.

The AHP method involves breaking down the decision problem into a hierarchy of criteria and sub-criteria. The decision-maker assigns weights to each criterion based on their relative importance. Then, the alternatives (different car options) are evaluated against each criterion, and pairwise comparisons are made to determine their relative performance. These comparisons are converted into numerical values using a scale, such as the Saaty scale, to establish the preference of one alternative over another.

By applying mathematical calculations and aggregating the preferences, the AHP method generates a final ranking of the car alternatives based on their overall performance across the criteria. This enables the decision-maker to select the car that aligns most closely with their preferences and satisfies the desired criteria, considering factors such as price, fuel efficiency, safety features, comfort, reliability, and others.

The power and thermal efficiency of this engine is equal to 241 Kilowatts and 48.2% respectively.

First of all, we would determine the thermal efficiency of this engine by applying the following formula:

\(\eta= 1-\frac{1}{r_p^{k-1/k}} \\\\\eta= 1-\frac{1}{10^{1.4-1/1.4}} \\\\\eta= 1-\frac{1}{10^{0.4/1.4}}\\\\\eta= 1-\frac{1}{10^{0.4/1.4}}\\\\\eta= 1-\frac{1}{10^{0.2857}}\\\\\eta = 0.482\)

Thermal efficiency = 48.2%.

Now, we can determine net power output as follows:

Note that ,the work done in lifting a 300 N weight to a height of 10 m with an acceleration of 0.5 m/s² is 3000 Joules.

To calculate the work done in lifting a 300 N weight to a height of 10 m, we need to use the formula  -

Work = Force x Distance

In this case, the force is the weight being lifted, which is 300 N, and the distance is the height the weight is lifted, which is 10 m.

Work = 300 N x 10 m

= 3000 N·m

= 3000 J (Joules)

When a large modern aircraft employs a variable incidence tailplane, the trim changes are made by adjusting the angle of the entire tailplane.

So, the correct answer is B.

This type of tailplane is designed to be adjustable in flight, allowing the pilot to change the angle of incidence and thus the lift generated by the tailplane.

This adjustment is made using an actuator or hydraulic system, which moves the entire tailplane up or down. This allows the pilot to adjust the aircraft's pitch attitude without changing the elevator deflection.

This is different from a fixed incidence tailplane, which relies on the trim tab on the trailing edge of the elevator to adjust the aircraft's pitch attitude. The spring bias trimming system and Q feel unit are not directly related to the operation of a variable incidence tailplane.

14.5° ; THD % = 3.873 × 100 = 387.3%.

Explanation:

Okay, in this question we are given the following parameters or data or information which is going to assist us in solving the question efficiently and they are;

(1). "500 VAR reactive power from 230 Vrms 50 Hz 1.5 KVAR reactor".

(2). Consideration of up to 12th harmonic.

So, let us delve right into the solution to the question above;

Step one: Calculate the Irms and Irms(12th) by using the formula for the equation below;

Irms = reactive power /Vrms = 500/230 = 2.174 A.

Irms(12th) = 1.5 × 10^3/ 12 × 230 = 0.543 A.

Step two: Calculate the THD.

Before the Calculation of the THD, there is the need to determine the value for the dissociation factor, h.

h = Irms(12th)/Irms = 0.543/ 2.174 = 0.25.

Thus, THD = [1/ (h)^2 - 1 ] ^1/2. = 3.873.

THD % = 3.873 × 100 = 387.3%.

Step four: angle AC - Ac converter

theta = sin^-1 (1.5 × 10^3/ 12 × 500) = 14.5°.

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

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).
