Answer:

a)123.37 mW

b) 58.75 mJ

Explanation:

a) The current (i) flowing through the terminal is given as:

\(i=\frac{dq}{dt} \\i=\frac{d(5sin(4\pi t)}{dt} =20\pi cos(4\pi t)\ mA\\\)

The Power delivered to the element (P(t)) is given as:

\(P(t)=v(t)i(t)= 3 cos(4\pi t)*20\pi cos(4\pi t)*10^{-3}\\P(t)=60\pi cos^2(4\pi t)*10^{-3}\\at \ t \ =\ 0.3s,\ the \ power\ delivered\ is:\\P(0.3) = 60\pi cos^2(4\pi *0.3)*10^{-3}=123.37mW\)

b)  the energy delivered to the element (W) between 0 and 0.6 s is given as:

\(W = \int\limits^0_{0.6} {P(t)} \, dt \\W=\int\limits^0_{0.6} {60\pi cos^{2}(4\pi t)} \, dt =58.75mJ\)

Answer:

Therefore, the stress on the wire is 1.05 x 10^9 Pa.

Explanation:

To calculate stress, we need to know the force applied to the wire and its cross-sectional area.

The first step is to calculate the cross-sectional area of the wire:

A = πr² = π(0.75mm)² = π(0.00075m)² = 5.58 x 10^-7 m²

Next, we need to calculate the force applied to the wire due to the weight of the mass:

F = m*g = 60kg * 9.81 m/s² = 588.6 N

Now we can calculate the stress:

stress = F/A = 588.6 N / 5.58 x 10^-7 m² = 1.05 x 10^9 Pa

Therefore, the stress on the wire is 1.05 x 10^9 Pa.

The body makes sure there is an efficient and safe system for a navigation and they also control air traffic.

To determine the shear and moment throughout the beam as a function of x, we need more specific information about the beam and the applied loading.

1. Identify the type of beam: Determine if the beam is simply supported, cantilever, or has other boundary conditions. This will help you establish the appropriate support reactions.

2. Determine the applied loading: Identify the magnitude and distribution of the applied loading along the beam. This can include point loads, distributed loads, moments, etc. Make sure to consider any concentrated or distributed loads acting on the beam.

3. Calculate the support reactions: Use the equations of equilibrium to determine the reactions at the supports. This involves summing the forces and moments acting on the beam.

4. Establish the shear force equation: Based on the applied loading and support reactions, you can determine the equation for the shear force along the beam. This equation will change depending on the loading configuration and any discontinuities in the loading.

5. Integrate to find the moment equation: Integrate the shear force equation with respect to x to obtain the moment equation. This equation will represent the moment at any given point along the beam.

By following these steps and applying appropriate equations and formulas, you can determine the shear and moment as functions of x for a given beam and loading configuration. It's important to note that the specific details of the problem, such as the beam type, loading, and boundary conditions, will dictate the exact calculations needed.

a. The power factor is 0989

b. The average power from the source is 2.125 kW

Power factor is the ratio of the real power absorbed by the load to the apparent power.

a. What is the power factor.

To find the power factor, we nedd to find the equivalent impedance of the circuit.

First, the the 8Ω resistor and -j6 Ω capacitor impedance are in series, their equivalent impedance is Z₁ = 8 Ω+ (- j6) Ω = (8 - j6)Ω.

Now, Z₁ is parallel to the Z₂ = j4 Ω impedance.

So, their equivalent inpedance is

Z₃ = Z₁Z₂/(Z₁ + Z₂)

= (8 - j6)j4 Ω/(8 - j6 + j4)

= (32 - j24)/(8 - j2)

Rationalizing the denominator, we have that

=  (32 - j24)/(8 - j2) × (8 + j2)/(8 + j2)

= [32 × 8 + 32 × j2 - j24 × 8 + (-j42 × -j2)]/(8² + 2)²

= [256 + j64 - 192j + j²84)]/(8² + 2²)

= [256 + j64 - 192j - 84)]/(64 + 4)

= (172 - j128)/68

= (43 - j32)/17

Since the 10 Ω resistor is in series with Z₃, the equivalent impedance is

Z₄ = 10 Ω + (43 - j32)/17 Ω

= (10 + 43/17 - j32/17 )Ω

= (170 + 43)/17 - j32/17

= 213/17 - j32/17

We know that for an impedance Z = a + jb , tanФ = b/a

So, for Z₄, tanФ = b/a

= -32/17 ÷ 213/17

= -32/213

since the trigonometric identity

tan²Ф + 1 = sec²Ф

secФ = ±√(tan²Ф + 1)

So, substituting tanФ into the equation, we have that

secФ = ±√(tan²Ф + 1)

secФ = ±√[(-32/213)² + 1)

= ±√[(1024 + 45369)/45369)]

= ±√[46393/45369)]

= ±215.39/213

Now, the power factor P.F = cosФ

Since secФ = 1/cosФ

cosФ = ±213/215.39

= ±0.989

Since tanФ is negative, Ф is in the fourth quadrant.

So, cosФ = 0.989

So, the power factor is 0989

b. The average power

The average power P = I²R where

Now, I = V/Z₄ where

We know that for an impedance Z = a + jb , tanФ = b/a

So, for Z₄ = , tanФ = b/a

= -32/17 ÷ 213/17

= -32/213

Ф = tan⁻¹(-32/213)

= -8.544

Also, the magnitude of impedance, Z = √(a² + b²)

So, the magnitude of Z = √[(213/17)² + (-32/17)²]

= √[(213)² + (-32)²]/17

= √[45369 + 1024]/17

= 215.39/17

= 12.67

So, Z = 12.67 ∠-8.544

So, the current I = V/Z

= 165 ∠ 0°/ 12.67 ∠-8.544

= 165/12.67 ∠ 0°- (-8.544)

= 13.02 ∠ 8.544° A

So, the average power P = I²R where

so, P = (13.02 A)² × 213/17 Ω

= 169.60 A² × 213/17 Ω

= 36123.754/17 A²Ω

= 2124.93 W

= 2.125 kW

The average power is 2.125 kW

In conclusion, the deficiency description for a dimension lumber floor joist with a clear span longer than allowed is that it is undersized or inadequately designed, requiring proper sizing or design modifications to ensure structural integrity and safety.

The most accurate deficiency description for a dimension lumber floor joist that is not deformed but has a clear span longer than allowed by current standards is that it is undersized or inadequately designed.
When a floor joist is not deformed but has a clear span longer than allowed, it means that the joist is unable to adequately support the load it is intended to carry over that span. This can lead to structural issues, such as excessive deflection or sagging, which can compromise the integrity and safety of the floor system.
To rectify this deficiency, the floor joist needs to be appropriately sized or designed to meet the required standards and support the anticipated loads. This may involve increasing the joist size or incorporating additional support, such as beams or columns, to reduce the span length and distribute the load more effectively.

1. the interference value, i

2. the radial pressure at the interference of the collar and the rod

3. the maximum effective stress in the collar

4. if the yield strength of aluminium is 200 MPa and assume a safety factor of 1.5, will the aluminium collar break

Solution:

Given :

Inner radius of the collar = 1 cm

So, inner diameter, \($d_1$\) = 2 cm

Outer radius of the collar = 12 cm

So, outer diameter, \($d_2$\) = 4 cm

The aluminium rod diameter, d = 1.01 cm
