To determine the vertical displacement of joint A using the method of virtual work, we need to first find the forces in each member. We can do this by using the method of sections and analyzing the left and right sides separately.

Starting with the left side, we can sum the vertical forces to get:
3k - F1*sin(45) - F2*sin(45) = 0
where F1 and F2 are the forces in members AB and AC, respectively.

Similarly, summing the moments about point A gives:
-8*F1*sin(45) - 12*F2*sin(45) = 0

Solving these two equations, we get F1 = 4.5 kips and F2 = 3 kips.

Now we can use the method of virtual work to find the displacement of joint A. We will apply a virtual load of 1 kip in the upward direction at joint A and find the corresponding change in potential energy of the structure.

The virtual work done by this load is:
Wv = 1*(3/12) = 0.25 in-kips

The change in potential energy is given by:
ΔU = F1*δ1 + F2*δ2
where δ1 and δ2 are the displacements in members AB and AC, respectively.

Using the principle of virtual work, we can equate the virtual work done to the change in potential energy:
Wv = ΔU

Substituting in the values we found earlier, we get:
0.25 = 4.5*δ1 + 3*δ2

We also know that the total vertical displacement at joint A is given by:
δA = δ1 + δ2

To solve for δA, we can use the fact that the displacement of any point in a structure is equal to the partial derivative of the total potential energy with respect to the force at that point. This is known as Castigliano's theorem.

Taking the partial derivative of ΔU with respect to F1, we get:
δ1 = -∂ΔU/∂F1 = -4.5*(12/29)/sin(45) = -1.33 in

Taking the partial derivative of ΔU with respect to F2, we get:
δ2 = -∂ΔU/∂F2 = -3*(12/29)/sin(45) = -0.89 in

Substituting these values into the equation for δA, we get:
δA = -1.33 - 0.89 = -2.22 in

Therefore, the vertical displacement of joint A is -2.22 in.

An airplane's glide ratio is the amount of altitude it loses for every unit of distance traveled forward. As a result, you may use glide ratio to figure out how much altitude an aircraft would lose when gliding a specific distance.

Let’s assume that the glide ratio of the aircraft is 1:10, implying that the plane can glide for every 1 mile forward it travels, it loses ten miles of altitude.

If the altitude loss ratio is 1:10, then the airplane will lose 30 times the altitude loss in 3 miles of gliding. If the altitude loss is 100 feet per mile, the airplane will lose 3000 feet in 3 miles of gliding.

To convert feet to meters, multiply by 0.3048.

3000 feet is equal to 914.4 meters.

To summarize, if the altitude loss ratio is 1:10, and the airplane's altitude loss is 100 feet per mile, then the airplane will lose approximately 914.4 meters of altitude in 3 miles of gliding at an angle of attack of 8°.

Answer: A sample of the representative outcomes or sequences of events for all possible consequences of a model is called a scenario.

Using this learning curve model, the average cumulative times to produce (a) the second unit is 6.54 min  (b) the 10th unit is 4.39 min and (c) the 100th unit is 2.46 min (d) Find the total cumulative time for the 100 units and the unit time is 1.84 min.

The learning curve theory has proposed that the efficiency of a learner in a task gets improved by the time. The more the learner performs the task, the better is the performance.

a) m =ln (0.84)/ln2 = -0.25154

T2 = 7.83 (2)^(-0.25154) = 7.84 x 0.84 = 6.54 min

b) T10 = 7.83 x (10)^(-0.25154) = 7.84 x 0.5604 = 4.39 min

c) T100 = 7.83 x (100)^(-0.25154) = 7.84 x 0.3140= 2.46 min

Thus, the average cumulative times to produce (a) the second unit is 6.54 min  (b) the 10th unit is 4.39 min and (c) the 100th unit is 2.46 min

The total cumulative time for 100th unit is

d) TT100 =7.873 x (100)^(1-0.25154) = 7.84 x 31.40= 245.86 min

TT99 = =7.873 x (99)^(1-0.25154) = 7.84 x 31.164= 244.02 min

T100 = 245.86 -244.02 = 1.84 min

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.

The time base for a one-minute delay timer with a preset value of 600 in this PLC is 0.1 seconds. To determine the time base for a one-minute delay timer in a PLC (Programmable Logic Controller) with a preset value of 600, we need to consider the resolution or scaling factor of the timer instruction.

The time base refers to the time increment represented by each unit of the timer's preset value. In other words, it determines how the preset value corresponds to actual time.

Given that the preset value is 600 and we want to achieve a one-minute delay, we can set up the following equation:

Preset Value × Time Base = Time Delay

Substituting the values, we have:

600 × Time Base = 1 minute

To find the time base, we rearrange the equation:

Time Base = 1 minute / 600

Simplifying the calculation:

Time Base = 1/600 minute

Since there are 60 seconds in a minute, we can convert the time base to seconds:

Time Base = (1/600) minute × (60 seconds / 1 minute)

Time Base = 0.1 seconds

Therefore, the time base for a one-minute delay timer with a preset value of 600 in this PLC is 0.1 seconds.

Percent reduction of bacteria should be \($(1-10^{0.99}) \times 100 =89.7\%$\)

Volume of the unit chamber is fixed at 2L

Assume the inlet concentration, \($C_0$\) as 1000

The outlet concentration of bacteria, C should be \($1000-\left(1000 \times \frac{89.7}{100}\right)$\)

                                                                                  = 103

The well mixed chamber will then follow a completely mixed flow reactor model.

Compute the time required :

\($t=\frac{1}{k}\left(\frac{C_0}{C}-1\right)$\)

\($t=\frac{1}{7.8}\left(\frac{1000}{103}-1\right)$\)
