As an Engineer assigned in the casino you are tasked to use IC 74LS00 (Quad Two Input NAND Gate), the output if all slots has logic 1 is 00.

Hence, the correct option is OF 01 Ob 00. Question 2As a designer, it is required to know the number of IC you will need to implement your output in NAND gate. We know that IC 74LS00 has four 2-input NAND gates on it. Since the task is to use IC 74LS00, only one IC is required to implement the output in the NAND gate. Hence, the correct option is 01. Question 3The task is to determine how many times De Morgan's Law will be applied in the SOP form if the output is implemented using NAND gate.

Answer:

The answer is "\(I = 0.0085106383 \ A\)"

Explanation:

Given:

\(R= 470 \ \Omega \\\\V= 4 \ v\)

Formula:

\(\to V=IR\\\\\to I = \frac{V}{R}\\\\\)

      \(= \frac{4}{470}\\\\ = 0.0085106383 \ A\)

The force acting on the aortic arch is -1907.26 N as per the given data.

The relationship between pressure, kinetic energy, and gravitational potential energy of a fluid in a container is known as Bernoulli's equation.

To determine the force acting on the aortic arch, we need to convert the units of velocity, pressure, and diameter to SI units (m/s, Pa, and m respectively).

Then, we can use the principle of continuity of flow and the equation of energy conservation (Bernoulli's equation) to calculate the force.

First, we'll convert the velocity, pressure, and diameter:

V1 = 90 cm/s = 0.9 m/s

P1g = 120 mmHg = 120 x 133.322 Pa = 16039.64 Pa

P2g = 115 mmHg = 115 x 133.322 Pa = 15345.83 Pa

d1 = 27 mm = 0.027 m

d2 = 22 mm = 0.022 m

Next, we'll use the principle of continuity of flow to calculate the velocity at the outlet (V2) and cross-sectional area (A2):

A1 x V1 = A2 x V2

\(V2 = V1 X (A1 / A2) = 0.9 x (\pi X (0.027^2) / 4) / (\pi X (0.022^2) / 4) = 1.33 m/s\)

Finally, we'll use Bernoulli's equation to calculate the pressure at the outlet (P2) and then calculate the force acting on the aortic arch:

\(P1g + (1/2) X \rho X V_1^2 = P2g + (1/2) \rho X V_2^2\)

\(P2 = P1g + (1/2) X \rho X V_1^2 - (1/2) X \rho X V_2^2 = 16039.64 + (1/2) X 1.057 X 0.9^2 - (1/2) X 1.057 X 1.33^2 = 14159.56 Pa\)

\(F = (P_2 - P_1g) X A1 = (14159.56 - 16039.64) X \pi X (0.027^2) / 4 = -1907.26 N\)

Thus, the force acting on the aortic arch is -1907.26 N. The negative sign indicates that the force is acting in the opposite direction to the flow, which is normal in fluid mechanics.

Answer:

  C.  3325 Ω - 3675 Ω

Explanation:

5% of 3500 Ω is ...

  0.05 × 3500 = 175

The lower limit is this amount less than the nominal value:

  3500 -175 = 3325

The upper limit is the nominal value plus the tolerance:

  3500 +175 = 3675

The lower and upper limits are 3325 Ω and 3675 Ω, respectively.

To calculate the factor of safety against yielding, we need to know the yield strength of the material. Assuming that the material is known, we can use the following formula:

Factor of safety against yielding = Yield strength / Maximum stressIf we assume a yield strength of 750 lbf, and a maximum stress of 500 lbf (which occurs at the maximum load), the factor of safety against yielding would be 750 / 500 = 1.5.To calculate the factor of safety against fatigue at infinite life, we need to know the endurance limit of the material. Assuming that the endurance limit is 250 lbf, and the maximum stress is 500 lbf, the factor of safety against fatigue at infinite life would be 250 / 500 = 0.5.

The large modulus of elasticity and the magnitude of the thickness of the

cylinder allows it to support the heavy load with minimal deformation.

Reasons:

Length of the cylinder, L = 2 m

Outside diameter of the cylinder, \(D_o\) = 50 mm

Internal diameter of the cylinder, \(D_i\) = 20 mm

Load applied to the cylinder, P = 25 kN = 25,000 N

Modulus of elasticity of the material, E = 100 GPa

First part; To find the stress in in the cylinder, σ

Solution:

\(\displaystyle Tensile \ stress, \ \sigma = \mathbf{\frac{Load \ applied}{Cross\ sectional \ area}} = \frac{P}{A}\)

The cross sectional area of the cylinder, A = \(\displaystyle \mathbf{\frac{\pi}{4} \cdot \left(D_o^2 - D_i^2 \right)}\)

Therefore;

\(A = \displaystyle \frac{\pi}{4} \cdot \left(\left(50 \, mm \right)^2 - \left(20 \, mm\right)^2 \right) \approx \mathbf{ 1,649.336 \, mm^2}\)

\(\displaystyle Tensile \ stress, \ \sigma = \frac{25,000 \, N}{1,649.336 \, mm^2} \approx 15.158 \, N/mm^2 = \mathbf{ 15.158 \, MPa}\)

Second part;

The deformation of the cylinder is found as follows;

\(\displaystyle Modulus \ of \ Elasticity, \, E = \mathbf{\frac{Tensile \ stress}{Tensile \ strain}} = \frac{\sigma}{\epsilon}\)

\(\displaystyle \epsilon = \mathbf{\frac{\delta L}{L}}\)

Therefore;

\(\displaystyle E = \frac{\sigma}{\frac{\delta L}{L} }\)

\(\displaystyle \frac{\delta L}{L} = \frac{\sigma}{E}\)

Which gives;

\(\displaystyle \delta L = \mathbf{\frac{\sigma}{E} \times L}\)

Where;

δL = The deformation of the cylinder

\(\displaystyle \delta L = \frac{15.158 \, N/mm^2}{100 \, GPa} \times 2,000 \, mm = \frac{15.158 \, MPa}{100 \times 10^3 \, MPa} \times 2,000 \, mm \approx \mathbf{0.303 \, mm}\)

Tech B is correct. In the neutral position, the pressure in a hydraulically controlled power steering system is typically low, not high.

A torsion bar is indeed used to operate the control valve in a hydraulically controlled power steering system. The torsion bar is responsible for transmitting the rotational force from the steering wheel to the control valve, which then controls the flow of hydraulic fluid to assist with steering.

In the neutral position, the power steering system is designed to have low pressure. This allows for easier manual steering without the assistance of hydraulic power. When the steering wheel is turned, the control valve directs pressurized fluid to the appropriate side of the steering mechanism, providing power assistance.

It is important to note that high pressure in the power steering system can indicate a problem or a malfunction, such as a blockage or a faulty component.

The stress state described in the question, where only a single pair of shearing stresses exist (t12 = t21 = t) and all other stress components are zero, is known as simple shear.

(a) To find the principal values and principal directions of this stress state, we need to determine the eigenvalues and eigenvectors of the stress tensor. In this case, the stress tensor can be represented as a 2x2 matrix:

[0  t]
[t  0]

To find the eigenvalues, we solve the characteristic equation:

det([0  t] - λ[I]) = 0

where [I] is the identity matrix and λ represents the eigenvalues.

Expanding this determinant equation, we get:

(-λ)(-λ) - t*t = 0

λ^2 - t^2 = 0

This equation can be factored as (λ - t)(λ + t) = 0, which gives us two possible eigenvalues: λ1 = t and λ2 = -t.

Next, we find the corresponding eigenvectors for each eigenvalue. For λ1 = t, we solve the equation ([0  t] - t[I])x = 0:

[0  t] - t[t1] = [0]
[t  0]     [t2]

This simplifies to:

[0  0]     [0]
[t  0]x = [0]

The solution to this equation is x1 = [1 0]T.

Similarly, for λ2 = -t, we solve the equation ([0  t] + t[I])x = 0:

[0  t] + t[t1] = [0]
[t  0]     [t2]

This simplifies to:

[0  0]     [0]
[t  0]x = [0]

The solution to this equation is x2 = [0 1]T.

(b) To find the maximum shearing stress and the planes on which it acts, we can use the formula for the maximum shear stress, which is half the difference between the principal values:

τmax = (t - (-t))/2 = t

The planes on which the maximum shearing stress acts are perpendicular to the principal directions [1 0] and [0 1].
