To find the damping constant c, we need to consider both the overshoot and rise time specifications.

We determine the natural frequency ωn of the system. The natural frequency is related to the damping constant c and the undamped natural frequency wn0 by

ωn = ωn0 × √(1 - c^2)

From the graph provided, we can see that the maximum percentage overrun is 20%. This means that the response of the system to a step input oscillates around steady state with an amplitude of 20% of steady state. You can find ωn using the percent overshoot formula for a second-order system.

% overshoot = e^(-c × ωn × π ÷ √(1-c^2))

Solving this equation for ωn gives us:

ωn = -ln(20%) / (c × π / √(1-c^2))

(a) The natural frequency of the system is ωn = -ln(20%) ÷ (c × π / √(1-c^2)).

(b) Because of the overshoot specification, the range of c is c >= -ln(20%) ÷ (ωn × π ÷ √(1-c^2)).

(c) Because of the rise time specification, the restrictions on c are c <= 3 × √(1 - c^2) ÷ π and ωn >= 3 ÷ π.

(d) The damping constant c is the intersection of the range determined by the overshoot specification and the constraint determined by the rise time specification. Both specifications are not met because the range specified by the overshoot specification is larger than the limit specified by the rise time specification.

Two technicians are discussing the a series-parallel brake lamp circuit that does not illuminate.

The statement made by Technician A saying that an open in one of the parallel branches could be the cause has no ground because an opening in any branches has not to do with the issue since there is no disconnection The statement made by Technician B saying that a shorted (or stuck closed) brake lamp switch wired in series could be the cause is correct.

Solution :

Given :

d = diameter of the wire of the spring = 0.074 in

  = 0.188 cm

R = mean radius of coil \($=\frac{0.85}{2}$\)

                                      = 1.08 cm

G = modulus of rigidity of carbon steel wire = \($79 \ GN/m^2$\)

L = length of wire of spring = 2 inch

∴ L = 5.08 cm

k = spring constant

k = axial load/ axial deflection

 \($k= \frac{Gd^4}{64R^3}$\) ..................(1)

This is taken from the Torsion equation,

\($\frac{T}{I_P}=\frac{\tau_{max}}{d/2}=\frac{G \theta}{2 \pi R}$\)

\($\frac{WR}{\frac{\pi}{32} d^4} = \frac{\tau_{max}}{d/2} =\frac{G \theta}{2 \pi R}$\)

∴ From equation (1)

\($k =\frac{79 \times 10^9 \times (0.188)^4 \times 10^{-8}}{64 \times (1.08)^3 \times 10^{-6}}$\)

\($k = 11334 \ N/m $\)

So the axial compression is \($ \delta =0.618 \ inch$\) = 1.57 cm

Axial load required W= k x δ

                                   = 11334 x 1.57

                                   = 177.95 N

To determine the steady-state error constants Kp, Kv, and Ka, we first need to find the open-loop transfer function G(s) for the given system.

Based on your provided information, G(s) is:
G(s) = 5(S+7) (S +11) / S^2(S +4)(S+2)(S + 9)
Now, we will calculate the steady-state error constants for the closed-loop system:
1. Position constant Kp:
To find Kp, we use the formula Kp = lim (s→0) [G(s)]. Since G(s) has an integrator (S^2 term in the denominator), Kp will be infinite. This means there will be zero steady-state error for a unit step input.
2. Velocity constant Kv:
To find Kv, we use the formula Kv = lim (s→0) [sG(s)]. For this system, Kv equals:
v = lim (s→0) [5(S+7)(S+11)] / [(S+4)(S+2)(S+9)]
Kv = 5(7)(11) / (4)(2)(9) = 38.5

With a finite Kv, the steady-state error for a unit ramp input will be ess_ramp = 1/Kv = 1/38.5 ≈ 0.026.
3. Acceleration constant Ka:
To find Ka, we use the formula Ka = lim (s→0) [s^2G(s)]. Since G(s) already has an integrator (S^2 term in the denominator), Ka will be infinite. This means there will be zero steady-state error for a unit parabolic input.

In summary:
- Kp = infinite, ess_step = 0
- Kv = 38.5, ess_ramp ≈ 0.026
- Ka = infinite, ess_parabolic = 0
These results show that the system has zero steady-state error for unit step and unit parabolic inputs and a small steady-state error for unit ramp inputs.

The stresses in steel and concrete are 1,631.29 MPa and 0.2535 MPa respectively.

The extension of column due to the load is 0.0017mm

To find the stresses in the steel and concrete, we need to use the principle of stress-strain proportionality. The formula for stress is:

Stress (σ) = Load (P) / Area (A)

The area of the steel rods is:

A = (π/4) * (25 mm)^2 = 490.87 mm^2

The area of the concrete is:

A = (π/4) * (600 mm)^2 = 314,159 mm^2

The stress in the steel is:

σ_steel = P / A = 800 kN / 490.87 mm^2 = 1,631.29 MPa

The stress in the concrete is:

σ_concrete = P / A = 800 kN / 314,159 mm^2 = 0.2535 MPa

To find the extension of the column, we need to use the formula for strain:

Strain (ε) = Extension (ΔL) / Original length (L)

We can use the principle of linear elasticity to find the extension of the column due to the load, which states that:

Stress = Young's modulus * Strain

We can use the formula of stress and strain to find the extension of the column:

ΔL = (PL)/(AE)

L = 600mm, P = 800kN and A =314,159 mm^2

ΔL = (80010^310^-360010^-3)/(314,1592510^9) = 0.0017 mm

Answer: A leak in the system

Explanation:

The correct option is(B). The height of the transverse metacentre above the centre of buoyancy is called metacentric height.

The height of the transverse metacentre above the centre of buoyancy is called metacentric height (GM).

The distance between the centre of gravity of a floating body and its metacentre is referred to as the metacentric radius.

GM determines the stability of a floating body.

Metacentric height (GM) is the term used to describe the distance between the center of gravity of a floating body and its metacentre.

It is the height of the transverse metacentre above the centre of buoyancy. When a ship is floating in calm water, it will come to a stable position after it is heeled because of the change in its centre of gravity and buoyancy.

The stability of the floating body is determined by the metacentric height (GM).When the GM value is high, the ship will have more stability, and it will be challenging to overturn it.

When the GM value is low, the ship will be less stable, and it will be easier to overturn. If the value of GM is zero, the ship will become unstable and will capsize.

Therefore, the value of GM is critical in the design of a ship and is calculated by naval architects to ensure the safety and stability of the vessel.

(b) The the angular acceleration of the rod, just before it touches the horizontal surface is 1.06 rad/s² .

Angular acceleration of the rod

The angular acceleration of the rod is calculated as follows;

Apply the principle of conservation of angular momentum;

τ = Iα

where;

τ is torque

I is moment of inertial of the rod

α is the angular acceleration

τ = Fr = mg(L/2) cosθ

I = mL²/3

The issue of electric and hybrid vehicles being difficult for the visually impaired to detect does indeed raise problems for engineers, similar to those raised by roundabouts. Both issues involve the need to balance different design considerations, including safety, accessibility, and sustainability.

One similarity between the problems is that both involve designing for the needs of vulnerable road users, such as the visually impaired or pedestrians. In the case of roundabouts, engineers must consider factors such as crosswalk placement, pedestrian signals, and traffic speeds to ensure that the roundabout is safe and accessible for all users. Similarly, in the case of electric and hybrid vehicles, engineers must consider strategies for making these vehicles more detectable to visually impaired pedestrians, such as adding noise-making devices or using special road markings.

However, there are also some differences between the problems. With roundabouts, the focus is on designing a physical infrastructure that is safe and accessible for all users. With electric and hybrid vehicles, the focus is on designing a vehicle that is both fuel-efficient and safe for all users, including pedestrians. This requires a different set of design considerations and trade-offs.

Another difference is that the problem of electric and hybrid vehicles being difficult to detect is a relatively new issue, while roundabouts have been in use for many years. As a result, the solutions to the problems may require different approaches and may involve more experimentation and testing with new technologies.

Overall, both the issues of roundabouts and electric/hybrid vehicles highlight the need for engineers to consider the needs of all users when designing transportation infrastructure and vehicles. By balancing safety, accessibility, and sustainability, engineers can create solutions that meet the needs of a diverse range of users and help create more inclusive and sustainable communities.
