Answer:

The answer is 960 kg

Explanation:

Solution

Given that:

Assume the initial dye concentration as A₀

We write the expression for the dye concentration for one hour as follows:

ln (C₁) = ln (A₀) -kt

Here

C₁ = is the concentration at 1 hour

t =time

Now

Substitute 480 g for C₁ and 1 hour for t

ln (480) = ln (A₀) -k(1) ------- (1)

6.173786 =  ln (A₀) -k

Now

We write the expression for the dye concentration for three hours as follows:

ln (C₃) = ln (A₀) -k

Here

C₃ = is the concentration at 3 hour

t =time

Thus

Substitute 480 g for C₃ and 3 hour for t

ln (120) = ln (A₀) -k(3) ------- (2)

4.787492 = ln (A₀) -3k

Solve for the equation 1 and 2

k =0.693

Now

Calculate the amount of blue present initially using the expression:

Substitute 0.693 for k in equation (2)

4.787492 = ln (A₀) -3 (0.693)

ln (A₀) =6.866492

A₀ =e^6.866492

= 960 kg

Therefore, the amount of the blue dye present from the beginning is  960 kg

The answer is true. Sheet metal processes are typically performed as cold working processes.

Cold working refers to the deformation of a metal below its recrystallization temperature. In sheet metal processes, such as bending, punching, shearing, and forming, the metal is manipulated at room temperature or slightly elevated temperatures without the need for heating. Cold working offers several advantages, including improved dimensional accuracy, increased strength and hardness, and better surface finish. It is a cost-effective method for shaping and forming sheet metal components. In contrast, hot working processes involve the deformation of metal at temperatures above its recrystallization temperature, which is not commonly used in sheet metal processes.

The value of impedance is 230,1 ohm.

The opposition to alternating current performed by the combined effect of resistance and reactance in a circuit is known as impedance. To determine the impedance, we can use this formula:

Z = \(\sqrt{R^{2} + (XL -XC)^{2} }\)

From the scenario we know that

ω = 231

L = 14.3 Mh

C = 9.71 μf = 9.71 x 10⁻⁶

V = 39 V

F = 6.1

Firstly we calculate the amount of XL using this formula

XL = 2πfL

XL =2 x 3.14 x 6.1 x 14.3

XL = 0.55 Ω

Then, we also determine the value of Xc

Xc = 1/2πfC

Xc = 1/(2 x 3.14 x 6.1 x 9.71)

Xc = 1/ 371.97 = 0.0026 Ω

After that substitue all the value into the formula to find the impedance

Z = \(\sqrt{R^{2} + (XL -XC)^{2} }\)

Z = \(\sqrt{231^{2}+(0.55-0.0026)^{2} }\)

Z = \(\sqrt{53,361-0.300}\)

Z = \(\sqrt{53,360}\)

Z = 230,1

If the aircraft's nose remains in the new position after the elevator control is pressed forward and released, the aircraft displays "static stability" in pitch.

Static stability in pitch refers to the aircraft's tendency to return to its original pitch attitude after a disturbance, such as a pilot input to the elevator control. In this case, if the aircraft's nose remains in the new position after the elevator control is pressed forward and released, it suggests that the aircraft is maintaining its new pitch attitude without any further pilot input, indicating that the aircraft is stable in pitch.

It's worth noting that static stability alone is not sufficient for safe and efficient flight. The aircraft must also exhibit dynamic stability and control, which involves the aircraft's response to changes in pitch over time, to ensure that it can be safely flown in a variety of conditions.

Answer:

Explanation:

The principal stresses are 9, 6, and -3, the maximum in-plane shear stress is 1.5, and the average normal stress is 4.

To determine the principal stresses, we need to find the eigenvalues of the stress tensor. The stress tensor for this problem can be represented by the following matrix:
[9  0  0]
[0  6  0]
[0  0 -3]
To find the eigenvalues, we need to solve the equation det(A-λI) = 0, where A is the stress tensor, I is the identity matrix, and λ is the eigenvalue. Solving this equation gives us the following eigenvalues:
λ1 = 9
λ2 = 6
λ3 = -3
The principal stresses are simply the eigenvalues, so the principal stresses for this problem are:
σ1 = 9
σ2 = 6
σ3 = -3
To find the maximum in-plane shear stress, we can use the formula:
τmax = (σ1 - σ2) / 2
Plugging in the values for σ1 and σ2 gives us: τmax = (9 - 6) / 2 = 1.5
Finally, to find the average normal stress, we can use the formula:
σavg = (σ1 + σ2 + σ3) / 3

Plugging in the values for σ1, σ2, and σ3 gives us:

σavg = (9 + 6 - 3) / 3 = 4

Therefore, the principal stresses are 9, 6, and -3, the maximum in-plane shear stress is 1.5, and the average normal stress is 4.

Explanation:

The image attached to the question is shown in the first diagram below.

From the diagram given ; we can deduce a free body diagram which will aid us in solving the question.

IF we take a look at the second diagram attached below ; we will have a clear understanding of what the free body diagram of the system looks like :

From the diagram; we can determine the length of BC by using pyhtagoras theorem;

SO;

\(L_{BC}^2 = L_{AB}^2 + L_{AC}^2\)

\(L_{BC}^2 = (3.5+2.5)^2+ 4^2\)

\(L_{BC}= \sqrt{(6)^2+ 4^2}\)

\(L_{BC}= \sqrt{36+ 16}\)

\(L_{BC}= \sqrt{52}\)

\(L_{BC}= 7.2111 \ m\)

The cross -sectional of the cable is calculated by the formula :

\(A = \dfrac{\pi}{4}d^2\)

where d = 4mm

\(A = \dfrac{\pi}{4}(4 \ mm * \dfrac{1 \ m}{1000 \ mm})^2\)

A = 1.26 × 10⁻⁵ m²

However, looking at the maximum deflection  in length \(\delta\) ; we can calculate for the force \(F_{BC\) by using the formula:

\(\delta = \dfrac{F_{BC}L_{BC}}{AE}\)

\(F_{BC} = \dfrac{ AE \ \delta}{L_{BC}}\)

where ;

E = modulus elasticity

\(L_{BC}\) = length of the cable

Replacing 1.26 × 10⁻⁵ m² for A; 200 × 10⁹ Pa for E ; 7.2111 m for \(L_{BC}\) and 0.006 m for \(\delta\) ; we have:

\(F_{BC} = \dfrac{1.26*10^{-5}*200*10^9*0.006}{7.2111}\)

\(F_{BC} = 2096.76 \ N \\ \\ F_{BC} = 2.09676 \ kN\)     ---- (1)

Similarly; we can determine the force \(F_{BC}\) using the allowable  maximum stress; we have the following relation,

\(\sigma = \dfrac{F_{BC}}{A}\)

\({F_{BC}}= {A}*\sigma\)

where;

\(\sigma =\) maximum allowable stress

Replacing 190 × 10⁶ Pa for \(\sigma\) ; we have :

\({F_{BC}}= 1.26*10^{-5} * 190*10^{6} \\ \\ {F_{BC}}=2394 \ N \\ \\ {F_{BC}}= 2.394 \ kN\)     ------ (2)

Comparing (1) and  (2)

The magnitude of the force \(F_{BC} = 2.09676 \ kN\) since the elongation of the cable should not exceed 6mm

Finally applying the moment equilibrium condition about point A

\(\sum M_A = 0\)

\(3.5 P - (6) ( \dfrac{4}{7.2111}F_{BC}) = 0\)

\(3.5 P - 3.328 F_{BC} = 0\)

\(3.5 P = 3.328 F_{BC}\)

\(3.5 P = 3.328 *2.09676 \ kN\)

\(P =\dfrac{ 3.328 *2.09676 \ kN}{3.5 }\)

P = 1.9937 kN

Hence; the maximum load P that can be applied is 1.9937 kN
