On the print you would expect the pitch diameter of the gear to be 9.00 inches. Option A is right.

Gear ratio = 1/3

This is solved as number of teeth on pinion / teeth on gear

= Np/Ng

The pitch diameter = 1.5 x 2

= 3

Diametral pitch = 12

NP = 3 x 12 = 36

This is the teeth on piston

Ng = 3NP

Ng = 3 * 36

The statement "The Critical Path Method does not assume activity path durations are fixed" is true.

The Critical Path Method (CPM) is a project management technique that uses a network diagram to identify the critical path, which is the sequence of tasks that must be completed on time to ensure the project is completed on schedule. In CPM, activity durations are estimated based on historical data, expert judgment, or other factors, and these estimates are not assumed to be fixed. Instead, they are updated as more information becomes available, and the project schedule is adjusted accordingly.

This flexibility is one of the strengths of CPM, as it allows for adjustments to be made in real-time, based on changing circumstances.

The question is incomplete. The complete question is --

An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 1.01 cm and the young's modulus of aluminum is 69 GPa, determine the following :

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

Now, from the figure, we can see that there will be no interference and so the rod will easily insert inside the collar.

1. So, the interference , i =0

2. The radial pressure is also 0.

3. There will be no stress developed. So the maximum effective stress is 0

4. The collar will not break

Answer: the stress is 384 pounds per square inch.

Step-by-step explanation:

Let S represent the stress in the material of the pipe.

Let P represent internal pressure of the pipe.

Let D represent internal diameter of the pipe.

Let T represent the thickness of the pipe.

The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. Introducing a constant of proportionality, k, the expression becomes

S = kPD/T

The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness is 0.75 inch, and the internal pressure is 25 pounds per square inch. It means that

100 = (k × 25 × 5)/0.75

125k = 100 × 0.75 = 75

k = 75/125 = 0.6

The equation representing the relationship becomes

S = 0.6PD/T

If the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inch, then the stress would be

S = (0.6 × 40 × 8)/0.5

S = 384

Explanation:

In the steady state total volume going out will be equal to total volume coming in , and

total salt coming in = total salt going out

Total volume coming in per minute = 2000 + 2 x 10³ x 60

= 122000 L .

Total salt coming in per minute = 1200 x 2000 + 20  x 2 x 10³ x 60

= 2400000 + 2400000 mg

= 4800000 mg

volume of water going out per minute = 122000 L

Total salt going out  per minute = 4800000 mg

concentration of water going out = 4800000 / 122000

= 39.344 mg / L

Answer:

Answer is explained in the explanation section below.

Explanation:

Solution:

Note: This question is incomplete and lacks necessary data to solve. But I have found the similar question on the internet. So, I will be using the data from that question to solve this question for the sack of concept and understanding.

Data Given:

x = 27 , 44 , 32 , 47, 23 , 40, 34, 52

y = 30, 19,  24,  13 , 29,  19,  21,  14

It is given that,

∑x = 299

∑y = 167

∑\(x^{2}\) = 11887

∑\(y^{2}\) = 3773

We are asked to verify the above values manually in this question.

So,

1. ∑x = 299

Let's verify it:

∑x = 27 + 44 + 32 + 47 + 23 + 40 + 34 + 52

∑x = 299

Yes, it is equal to the given value. Hence, verified.

2. ∑y = 167

Let's verify it:

∑y = 30 + 19 +  24 + 13 + 29 + 19 +  21 +  14

∑y = 169

No, it is not equal to the given value.

3. ∑\(x^{2}\) = 11887

Let's verify it:

For this to find,  first we need to square all the value of x individually and then add them together to verify.

∑\(x^{2}\) = \(27^{2}\) + \(44^{2}\) + \(32^{2}\) + \(47^{2}\) + \(23^{2}\) + \(40^{2}\) + \(34^{2}\) + \(52^{2}\)

∑\(x^{2}\) = 11,887

Yes, it is equal to the given value. Hence, verified.

4. ∑\(y^{2}\) = 3773

Let's verify it:

Again, for this we need to find the squares of all the y values and then add them together to verify it.

∑\(y^{2}\) = \(30^{2}\) + \(19^{2}\) +  \(24^{2}\) + \(13^{2}\) + \(29^{2}\) + \(19^{2}\) +  \(21^{2}\) +  \(14^{2}\)

∑\(y^{2}\)  = 3,845

No, it is not equal to the given value.

Answer:

The resulting pressure of the gas when its volume decreases is 300 kN/m².

Explanation:

Given;

initial volume of the gas, V₁ = 80 L

number of moles of the gas, n = 0.5 moles

initial pressure of the gas, P₁ = 150 kN/m² = 150 kPa

Determine the constant temperature of the gas using ideal gas equation;

PV = nRT

where;

R is ideal gas constant = 8.315 L.kPa/K.mol

T is the constant temperature

\(T = \frac{P_1V_1}{nR} \\\\T = \frac{150.kPa \ \times \ 80 .L}{0.5 .mol \ \times \ 8.315(L.kPa/mol.K)} \\\\T = 2,886.35 \ K\)

When the gas is compressed to half of its volume;

new volume of the gas, V₂ = ¹/₂ V₁

                                             = ¹/₂ x 80L = 40 L

The new pressure, P₂ is calculated as;

\(P_2V_2 = nRT\\\\P_2 = \frac{nRT}{V_2} \\\\P_2 = \frac{0.5 \times 8.315\times 2886.35}{40} \\\\P_2 = 300 \ kPa = 300 \ kN/m^2\)

Therefore, the resulting pressure of the gas when its volume decreases is 300 kN/m².

(A) The energy stored in the capacitor remains at 8.70J. (B) the energy stored in the capacitor would increase to: E₂ = E₁ × 2.37 = 8.70J × 2.37 = 20.65J.

(A) If the capacitor was disconnected from the potential source before the separation of the plates was changed, the energy stored in the capacitor would remain constant. This is because a capacitor stores energy in an electric field between its plates, and changing the plate separation without changing the voltage does not change the energy stored.

Therefore, the energy stored in the capacitor remains at 8.70J.

(B) If the capacitor remained connected to the potential source while the separation of the plates was changed, the voltage across the capacitor would change as the plate separation is decreased. The capacitance of a parallel-plate capacitor is given by:

C = ε₀A/d

Where C is the capacitance, ε₀ is the permittivity of free space, A is the area of the plates, and d is the distance between the plates.

As the separation is decreased from 3.80 mm to 1.60 mm, the capacitance would increase by a factor of:

C₂/C₁ = (ε₀A/1.60 mm)/(ε₀A/3.80 mm) = 2.37

The energy stored in a capacitor is given by:

E = 1/2CV²

Where E is the energy stored, C is the capacitance, and V is the voltage across the capacitor.

If we assume that the voltage across the capacitor remains constant, then the energy stored would increase by a factor of:

E₂/E₁ = (C₂V²/2)/(C₁V²/2) = C₂/C₁ = 2.37

Therefore, the energy stored in the capacitor would increase to:

E₂ = E₁ × 2.37 = 8.70J × 2.37 = 20.65J.

Answer:

I don't Know what it is supposed to equal.

Explanation:

Tell me this, and consider it done

To determine the convection heat flux in each scenario, we can use the formula Q = hA(T_surface - T_surrounding), where Q is the heat flux, h is the convection coefficient, A is the surface area, and T_surface and T_surrounding are the temperatures of the surface and the surrounding medium, respectively.

For scenario (a):
- Vehicle speed: 40 km/h
- Air temperature: -8°C
- Surface temperature: 30°C
- Convection coefficient: 40 W/m²·K

First, we need to convert the vehicle speed from km/h to m/s:
40 km/h = (40 * 1000) m / (60 * 60) s ≈ 11.11 m/s

Next, we can calculate the heat flux:
Q = 40 W/m²·K * A * (30°C - (-8°C))

Now, let's move on to scenario (b):
- Water stream velocity: 0.2 m/s
- Water temperature: 10°C
- Surface temperature: 30°C
- Convection coefficient: 900 W/m²·K

For this scenario, we can calculate the heat flux using the same formula:
Q = 900 W/m²·K * A * (30°C - 10°C)

To determine which condition feels colder, we compare the heat flux values. The higher the heat flux, the faster heat is transferred away from the hand, making it feel colder.

Now, let's compare the heat flux values with the approximate heat flux under normal room conditions (30 W/m²):
- If the heat flux is higher than 30 W/m², the condition would feel colder.
- If the heat flux is lower than 30 W/m², the condition would feel warmer.

To find the convection heat flux, we use the formula Q = hA(T_surface - T_surrounding). By calculating the heat flux for each scenario, we can determine which condition would feel colder by comparing the values with the approximate heat flux under normal room conditions.

Part A : Since the discriminant is negative, the roots are complex

The roots of the characteristic equation are -2.5 + 1.9365i and -2.5 - 1.9365i.

Part B : Since the new discriminant is also negative, the roots are complex

The roots of the characteristic equation are -2.5 + 99.9687i and -2.5 - 99.9687i.

Part C : For the response to be critically damped, the capacitance should be adjusted to 0.0001F.

To find the characteristic equation of the circuit, we can start by writing the differential equation governing the circuit's behavior. The equation for an RLC circuit is given by:

LC d²q/dt² + RC dq/dt + q = 0, where q is the charge on the capacitor.

Part A:

Given C = 100mF, L = 1H, and R = 5Ω, we can substitute these values into the differential equation:

(1H)(100mF) d²q/dt² + (5Ω)(100mF) dq/dt + q = 0

Simplifying, we get:

0.1 d²q/dt² + 0.5 dq/dt + q = 0

Now we can find the characteristic equation by assuming a solution of the form q = e^(st):

0.1s² + 0.5s + 1 = 0

Multiply the equation by 10 to get rid of the decimal:

s² + 5s + 10 = 0

Using the quadratic formula, we can find the roots of this equation:

s = (-b ± √(b² - 4ac)) / (2a)

Plugging in a = 1, b = 5, and c = 10:

s = (-5 ± √(5² - 4(1)(10))) / (2(1))

s = (-5 ± √(-15)) / 2

Since the discriminant is negative, the roots are complex:

s = (-5 ± √15i) / 2

Therefore, the roots of the characteristic equation are -2.5 + 1.9365i and -2.5 - 1.9365i.

Part B:

To find the new characteristic equation with a resonant frequency of 100 rad/s, we need to adjust the capacitance. The resonant frequency is given by:

ω = 1 / √(LC)

Substituting the given values, we have:

100 = 1 / √(1(100mF))

Squaring both sides and rearranging, we find:

10 = 1 / C

C = 1/10 = 0.1F

Now, we can find the new characteristic equation with this adjusted capacitance value. Substituting the values R = 5Ω, L = 1H, and C = 0.0001F into the characteristic equation, we have:

s^2 + (5/1)s + 1/((0.0001)(1)) = 0

s^2 + 5s + 10000 = 0

To find the root(s), we solve this quadratic equation:

s = (-5 ± √(5^2 - 4(1)(10000))) / 2(1)

Simplifying further:

s = (-5 ± √(25 - 40000)) / 2

s = (-5 ± √(-39975)) / 2

Again, the discriminant is negative, so the roots of the new characteristic equation are complex numbers:

s = (-5 ± √39975i) / 2

Part C:

For the response to be critically damped, the roots of the characteristic equation should be real and equal. Since we have already found the roots in Part B as complex conjugates, we need to find the capacitance value for which the roots become real and equal.

The characteristic equation is:

s = -2.5 ± 1.9365i

For the roots to be real and equal, the imaginary part must be zero. Therefore, we set 1.9365i equal to zero:

1.9365i = 0

This implies that s = -2.5. We can substitute this value into the resonant frequency equation:

ω = 1 / √(LC)

100 = 1 / √(1H * C)

Squaring both sides and rearranging, we have:

C = 1 / (100² * 1H)

C = 1 / 10,000 = 0.0001F

Therefore, for the response to be critically damped, the capacitance should be adjusted to 0.0001F.
