will the stock rods always meet the length constraint? explain.

The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.

The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;

∑F = 0

F - μF_n = 0

We are given;

F_n = 5 kN = 5000 N

μ = 0.2

Thus;

F - 0.2(5,000) = 0

F - 1,000 = 0

F = 1,000 N

The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;

Minimum force = Total force/number of turns of rope

Since rope is wrapped three and half times, then;

number of turns = 3.5

Thus;

minimum force = 1,000/3.5

minimum force = 285.7 N

Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

Allowable normal stress (σ_allow) = 139.5 MPa

Allowable shear stress (τ_allow) = 75 MPa

To determine the smallest allowable length (l) of beam CD without causing overstress, we first need to find the moment and shear forces acting on the beam.

A. Smallest allowable length of beam CD:

Calculate the total load on the beam:

Uniformly distributed load (w) = 66 kN/m

Span (L) = 6 m

Total load (W) = w * L = 66 kN/m * 6 m = 396 kN

Calculate the maximum moment (M_max) and shear force (V_max) on the beam:

For a simply supported beam with a uniformly distributed load, the maximum moment occurs at the center of the span and can be calculated as:

M_max = (w * L^2) / 8 = (66 kN/m * 6^2 m^2) / 8 = 198 kNm

The maximum shear force occurs at the supports and can be calculated as:

V_max = W / 2 = 396 kN / 2 = 198 kN

Determine the section modulus (S) and shear area (A_v) for the given W460 x 74 beam:

For a W460 x 74 beam, the section modulus (S) is approximately 1240 cm^3, and the area (A) is approximately 9,450 cm^2. We'll use these values to check the stress limits.

Calculate the actual normal stress (σ) and shear stress (τ) in the beam:

Normal stress (σ) = M_max / S

Shear stress (τ) = V_max / A_v

The smallest allowable length of beam CD will be the one where the actual normal and shear stresses do not exceed their allowable limits.

We will use trial and error to find the smallest length (l) of beam CD.

Let's start with the full length of the W460 x 74 beam (6 m) and calculate the stresses:

Normal stress (σ) = (198 kNm * 10^3 Nm/kN) / (1240 cm^3 * 10^-6 m^3/cm^3) = 159.68 MPa

Shear stress (τ) = (198 kN * 10^3 N/kN) / (9450 cm^2 * 10^-4 m^2/cm^2) = 20.95 MPa

Normal stress is greater than the allowable stress (159.68 MPa > 139.5 MPa), so the full length of the beam is not suitable. However, the shear stress is within the allowable limit (20.95 MPa < 75 MPa).

To reduce the normal stress, we can try to reduce the length (l) of the beam CD.

With trial and error, we can find the smallest length (l) where both normal and shear stresses do not exceed the allowable limits.

Keep in mind that reducing the length will increase the shear stress.

Answer:

2)

a)  to the right of the dipole    E_total = kq [1 / (r + a)² - 1 / r²]

b)To the left of the dipole      E_total = - k q [1 / r² - 1 / (r + a)²]

c) at a point between the dipole, that is -a <x <a  

      E_total = kq [1 / x² + 1 / (2a-x)²]

d) on the vertical line at the midpoint of the dipole (x = 0)

E_toal = 2 kq 1 / (a ​​+ y)² cos θ

Explanation:

2) they ask us for the electric field in different positions between the dipole and a point of interest. Using the principle of superposition.

This principle states that we can analyze the field created by each charge separately and add its value and this will be the field at that point

Let's analyze each point separately.

The test charge is a positive charge and in the reference frame it is at the midpoint between the two charges.

a) to the right of the dipole

The electric charge creates an outgoing field, to the right, but as it is further away the field is of less intensity

           E₊ = k q / (r + a)²

where 2a is the distance between the charges of the dipole and the field is to the right

the negative charge creates an incoming field of magnitude

           E₋ = -k q / r²

The field is to the left

therefore the total field is the sum of these two fields

           E_total = E₊ + E₋

           E_total = kq [1 / (r + a)² - 1 / r²]

we can see that the field to the right of the dipole is incoming and of magnitude more similar to the field of the negative charge as the distance increases.

b) To the left of the dipole

The result is similar to the previous one by the opposite sign, since the closest charge is the positive one

E₊ is to the left and E₋ is to the right

          E_total = - k q [1 / r² - 1 / (r + a)²]

We see that this field is also directed to the left

c) at a point between the dipole, that is -a <x <a

In this case the E₊ field points to the right and the E₋ field points to the right

                      E₊ = k q 1 / x²

                      E₋ = k q 1 / (2a-x)²

                      E_total = kq [1 / x² + 1 / (2a-x)²]

in this case the field points to the right

d) on the vertical line at the midpoint of the dipole (x = 0)

    In this case the E₊ field points in the direction of the positive charge and the test charge

    in E₋ field the ni is between the test charge and the negative charge,

the resultant of a horizontal field in zirconium on the x axis (where the negative charge is)

                      E₊ = kq 1 / (a ​​+ y) 2

                      E₋ = kp 1 / (a ​​+ y) 2

                      E_total = E₊ₓ + E_{-x}

                      E_toal = 2 kq 1 / (a ​​+ y)² cos θ

e) same as the previous part, but on the negative side

                        E_toal = 2 kq 1 / (a ​​+ y)² cos θ

When analyzing the previous answer there is no point where the field is zero

The different configurations are outlined in the attached

3) We are asked to repeat part 2 changing the negative charge for a positive one, so in this case the two charges are positive

a) to the right

in this case the two field goes to the right

           E_total = kq [1 / (r + a)² + 1 / r²]

b) to the left

            E_total = - kq [1 / (r + a)² + 1 / r²]

c) between the two charges

E₊ goes to the right

E₋ goes to the left

            E_total = kq [1 / x² - 1 / (2a-x)²]

d) between vertical line at x = 0

E₊ salient between test charge and positive charge

           E_total = 2 kq 1 / (a ​​+ y)² sin θ

In this configuration at the point between the two charges the field is zero

An airplane flying across the sky experience drag force determined by the factors including the speed of flight, coefficient of skin friction and the reference surface area

The boundary layer thickness is approximately 0.233 cm

The total skin friction drag, is approximately 265 N

Reason:

First part:

Given parameters are;

Chord length, L = 3 m

Velocity of the plane, V = 200 m/s

Density of the air, ρ = 1.225 kg/m³

Viscosity of the air, μ = 1.81 × 10⁻⁵ kg/(m·s)

The Reynolds number is given as follows;

\(R_{eL} = \dfrac{\rho \times V \times L}{\mu}\)

Therefore;

\(R_{eL} = \dfrac{1.255 \times 200 \times 3}{1.81 \times 10^{-5}} = 4.16022099448 \times 10^7 \approx 4.16 \times 10^7\)

Boundary layer thickness, \(\delta_L\), for laminar flow, is given as follows;

\(\dfrac{ \delta_L }{L}=\dfrac{5.0}{\sqrt{R_{eL} } }\)

\({ \delta_L }=\dfrac{5.0 \times L}{\sqrt{R_{eL} } }\)

Which gives;

\({ \delta_L }=\dfrac{5.0 \times 3}{\sqrt{4.16 \times 10^{7}} } \approx 2.33 \times 10^{-3 }\)

The boundary layer thickness, \(\delta_L\) ≈ 2.33 × 10⁻³ m = 0.233 cm

Second Part

The total skin friction is given as follows;

\(Dynamic \ pressure, q = \dfrac{1}{2} \cdot \rho \cdot V^2\)

Therefore;

\(q = \dfrac{1}{2} \times 1.225 \times 200^2 = 24,500\)

The dynamic pressure, q = 24,500 N/m²

Skin friction drag coefficient, \(C_D\), is given as follows;

\(C_D = \dfrac{1.328}{\sqrt{R_{eL} } }\)

Therefore;

\(C_D = \dfrac{1.328}{\sqrt{4.16 \times 10^7 } } \approx 2.06 \times 10^{-4}\)

Skin friction drag, \(D_f\), is given as follows;

\(D_f\) = q × \(C_D\) × A

Where;

A = The reference area

∴ \(D_f\) = 24,500 N/m² × 2.06 × 10⁻⁴ × 3 m × 17.5 m = 264.9675 N ≈ 265 N

The total skin friction drag, \(D_f\) ≈ 265 N

When a motor running at synch speed gets caught in a load, the torque increases while the speed and frequency decrease.

This is because the motor is no longer running at its synchronous speed, resulting in a decrease in frequency and speed while an increase in torque. What is synchronous speed? Synchronous speed is the speed at which a motor's rotating magnetic field moves. It is determined by the number of stator poles and the frequency of the supply current. A synchronous motor's rotor rotates at the same speed as its stator's rotating magnetic field at synchronous speed. What is torque? A torque is a rotational force that is applied to an object. It is the force that causes an object to rotate around a pivot point or axis. Torque is usually measured in units of Newton meters (N-m) or pound-feet (lb-ft). What is the frequency? In electrical engineering, frequency refers to the number of cycles per second of an alternating current (AC) signal. The frequency of an AC signal is measured in hertz (Hz), which is equivalent to cycles per second.

Along the zero to measure an object on a ruler

The given statement "The thermal resistance of a medium represents the resistance of that medium against heat transfer" is true. Further explanation is given below:

Thermal resistance, denoted as R, is a measure of the capacity of an element or a component to prevent heat flow. It is the difference between the temperature gradient across an object and the rate of heat energy transmission per unit area via that object. Thermal resistance, like electrical resistance, determines the efficiency of thermal energy transmission across a material.

The larger the thermal resistance, the more difficult it is to transfer heat through the material. As a result, the heat generated by a device's internal workings cannot be removed efficiently, causing it to overheat and ultimately fail. The SI unit of thermal resistance is the kelvin per watt, as in the case of electrical resistance. It is denoted by K/W. When selecting an insulating material, the thermal resistance of the material is critical.

A good insulator, such as air, has a high R-value, while a bad insulator, such as metal, has a low R-value. This is because metals are good heat conductors and so they have a low thermal resistance. Thus, it can be concluded that the given statement is true.
