Answer: I believe the answer is 963.75 if I am reading the question right.

Explanation:

ACH=60L/V

ACH=2.25

V=25,700

25,700*2.25=57,825

57,825/60=963.75

L=963.75

60(963.75)/25,700=2.25

The maximum amount of air leakage that would result in an ACH of no more than 2.25 would be approximately 956.25 cfm (cubic feet per minute).

Given that ACH of a house is a measure of its​ air-tightness and the formula for ACH is ACH = 60L/V. It means that ACH is inversely proportional to air-tightness or leakage. Therefore, the lower the air leakage the higher the ACH and vice versa.Mathematically, it is represented as:ACH ∝ 1/L or L ∝ 1/ACH

We can solve the question as follows:ACH = 2.25 (since the maximum ACH is 2.25)The volume of the house, V = 25,700 cubic feet.Substituting in the formula,2.25 = 60L/25,700Dividing both sides by 2.25 gives us,L = (2.25 * 25,700)/60L = 956.25 cubic feet per minute (cfm)

Therefore, the maximum amount of air leakage that would result in an ACH of no more than 2.25 is approximately 956.25 cfm (cubic feet per minute).

When two edge dislocations of opposite sign align with each other, a stacking fault defect is created. This occurs because the dislocations have opposite Burgers vectors, which causes the planes to be shifted in opposite directions.

The region between the two dislocations becomes compressed and the planes above and below are stretched, resulting in a stacking fault. This stacking fault has a different arrangement of atoms compared to the perfect crystal lattice, which creates a defect in the material. During annealing, the stacking fault defect can be eliminated through the process of climb. Climb is the movement of the dislocation line in a direction perpendicular to its slip plane. As the dislocation line climbs, it interacts with vacancies or interstitial atoms, which can be incorporated into the crystal lattice, and the stacking fault is gradually removed. This process requires a high enough temperature to enable the necessary atomic motion for climb to occur. In summary, when two edge dislocations of opposite sign align with each other, a stacking fault defect is created due to the compression and stretching of the planes between them. This defect is eliminated during annealing through the process of climb, which requires a high temperature to enable atomic motion.

We need to use the equation that relates the lift coefficient (CL) to the angle of attack (AOA):

CL = CL0 + k*AOA

Where CL0 is the lift coefficient at zero angle of attack, k is the lift curve slope (which tells us how much CL changes per degree of AOA), and AOA is the angle of attack.

We know that the aircraft is in straight, level flight, which means that the lift force is equal to the weight force, and the load factor is 1. Therefore, we can use the equation for lift force:

L = 0.5*rho*V^2*S*CL

Where L is the lift force, rho is the air density, V is the airspeed, S is the wing area, and CL is the lift coefficient.

Now, let's apply the gust that increases the AOA by 3 degrees. We can calculate the new CL using the given information:

CL = CL0 + k*AOA
CL = 0.42 + 0.1*3
CL = 0.72

Therefore, the new lift force is:

L = 0.5*rho*V^2*S*CL
L = 0.5*1.225*100^2*20*0.72
L = 132120 N

The load factor is the ratio of lift force to weight force:

n = L/W
n = L/(m*g)

Assuming a weight of 20 kN (which is the weight force in straight, level flight), we can calculate the load factor:

n = 132120/(20*1000*9.81)
n = 1.35

Therefore, the aircraft would be subject to a load factor of 1.35 after the gust. This is higher than the limit load factor of 1.4, which means that the pilot would need to take action to reduce the load factor (such as reducing speed or changing the aircraft's attitude) to avoid structural damage.

"typedef" allows us to create new functionality in our code by defining new data types, which leads to more modular, readable, and maintainable code.

Hence answer is "Yes"

"typedef" is a feature in C and C++ that allows programmers to create new data types from existing ones.

With typedef, you can create a more descriptive name for a data type, making the code more readable and self-explanatory.

It also helps in making code more modular, as you can change the underlying type for the typedef without affecting the rest of the code that uses it.

For example, you can create a new data type called "Meter" which represents the distance in meters, by typedef-ing a float data type.

So, instead of using the float type throughout your code, you can use the "Meter" type, which makes your code more readable and easier to maintain.

1) What is the cycle time for operation?

2) What is the theoretical minimum number of workstation?

Answer:

1) the cycle time for operation is 9.6 min

2) the theoretical minimum number of workstation is 5

Explanation:

Given the data in the question;

production time per day = 480 minutes

average daily demand = 50

Given the data in the question;

1) cycle time for operation

this is simply referred to as the total time for the process from start to finish.

cycle time = production time per day / units demand per day

we substitute

cycle time = 480 min / 50

cycle time = 9.6 min

Therefore, the cycle time for operation is 9.6 min

2) theoretical minimum number of workstation.

theoretical minimum number of workstation = total task time / cycle time

Total task time = ( 4 + 7 + 6 + 5 + 6 + 7 + 8 + 6 ) = 49 min

∴  theoretical minimum number of workstation = 49 min / 9.6 min

theoretical minimum number of workstation = 5.104 ≈ 5

Therefore, the theoretical minimum number of workstation is 5

The Wilcoxon-Mann-Whitney test is a non-parametric statistical test used to test the null hypothesis that two independent groups come from the same distribution. To carry out this test, we need to take the following steps:First, we rank the observations from lowest to highest.


We combine the ranks and then calculate the sum of the ranks for each group. We will then use these sums to calculate the test statistic (W). The sum of the ranks for group A is:67, 80, 106, 83, 89 = 5 + 6 + 9 + 7 + 8 = 35The sum of the ranks for group B is:45, 71, 87, 53 = 1 + 4 + 8 + 2 = 15The test statistic (W) is given by the equation:W = n1n2 + n1(n1 + 1)/2 - R1where n1 and n2 are the sample sizes of the two groups, R1 is the sum of the ranks for group A, and N is the total number of observations.
W = (5)(4) + (5)(6)/2 - 35 = 5The critical value for W is 1 at the 5% level of significance. Since W = 5, we can reject the null hypothesis that the two groups come from the same distribution.In order to use the t-test to compare the mean strengths of the two groups, we need to first check the normality assumption and equal variances. The normality assumption can be checked using a normal probability plot or a histogram.
The equal variance assumption can be checked using a boxplot or Levene's test.Assuming equal variances between groups, the null hypothesis is that the mean strengths of the two groups are equal.
The alternative hypothesis is that the mean strengths are different.Using the t-test, we obtain the following results:t = (mean A - mean B) / (s / sqrt(n))where s is the pooled standard deviation given by:s = sqrt(((n1 - 1)s1^2 + (n2 - 1)s2^2) / (n1 + n2 - 2))t = (mean A - mean B) / (s / sqrt(n)) = (85 - 64) / (14.11 / sqrt(9)) = 3.58The degrees of freedom for the t-test is given by df = n1 + n2 - 2 = 9 - 2 = 7The critical value for a two-tailed test with df = 7 at the 5% level of significance is 2.365. Since t = 3.58 > 2.365, we can reject the null hypothesis that the mean strengths of the two groups are equal.Therefore, we conclude that there is a real difference between the two types of special reinforced concrete beams.

In the given circuit, V(t)=12cos(2000t+45)V, R1=R2=2Ω, L1=L2=L3=3mH and C1=250μF. You are required to find the Thevenin equivalent of this circuit using phasors.

a. If you write the Thevenin voltage, Vth, in phasor form, what is the magnitude of this phasor? Put your answer in the box below without units.

b. What is the value of the angle associated with the phasor Vth, in degrees?

c. Now, calculate the Thevenin impedance, Zth. What is the magnitude of this phasor?

d. What is the angle associated with the phasor Zth, in degrees?

Answer:

Vth = 6 < 45° V

Zth = 1.414 < 45°

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°

Explanation:

The given voltage is

V(t)=12cos(2000t+45)

In phasor form,

V(t) = 12 < 45° V

So the magnitude of voltage is 12 V and the phase angle is 45°

Also the frequency ω = 2000

then the inductance is

L₁ = L₂ = L₃ = jωL = j×2000×0.003 = j6 Ω

and the capacitance is

C₁ = 1/jωC = 1/(j×2000×250x10⁻⁶) = -j2 Ω

and the resistance is

R₁ = R₂ = 2 Ω

Thevenin voltage:

The Thevenin voltage is the voltage that appears across the open-circuited terminals a-b (after removing L₃)

The Thevenin voltage is given by

Vth = V(t) × [ (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ]

Please note that there is no current flow in the capacitor due to open-circuited terminal a-b

Vth = 12 < 45°  × [ (2 + j6) / (2 + j6) + (2 + j6) ]

Vth = 12 < 45°  × [ (2 + j6) / (4 + j12) ]

Vth = 4.24264 + j4.24264 V

In phasor form,

Vth = 6 < 45° V

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

Thevenin Impedance:

The Thevenin Impedance is the impedance of the circuit calculated when looking from the terminal a-b

Zth = [ (R₁ + L₁) × (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ] + (-j2)

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (-32 + j24) / (4 + j12) ] -j2

Zth = [ (1 +j3) ] - j2

Zth = 1 + j Ω

In phasor form,

Zth = 1.414 < 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°
