Chapter 2, Problem 9PP

(Civil eng.) The maximum load that can be placed at the end of a symmetrical wooden beam, such as the rectangular beam shown in Figure 2.20, can be calculated as the following:

L = S × 1 d × c

L is the maximum weight in lbs of the load placed on the beam.

S is the stress in lbs/in2.

I is the beam’s rectangular moment of inertia in units of in4.

d is the distance in inches that the load is placed from the fixed end of the beam (the

“moment arm”).

c is one-half the height in inches of the symmetrical beam.

Chapter 2, Problem 9PP, (Civil eng.) The maximum load that can be placed at the end of a symmetrical wooden beam, such as

For a 2” × 4” wooden beam, the rectangular moment of inertia is given by this formula:

I = b a s e × h e i g h t 3 = 12 = 2 × 4 3 12 = 10.67 4

c   =   ½ ( 4   i n )   =   2   i n

a. Using this information, design, write, compile, and run a C++ program that computes the

maximum load in lbs that can be placed at the end of an 8-foot 2   ×   4 wooden beam so that

the stress on the fixed end is 3000   l b / i n 2 .

b. Use the program developed in Exercise 9a to determine the maximum load in lbs that can be placed at the end of a 3” × 6” wooden beam so that the stress on the fixed end is 3000   l b / i n 2 .

Please show the code for the Tikz figure of the complex plane and the curve C. Also, mark all singularities of the integrand.
11. Go to the Webinars worksheet. DeShawn wants to determine the number of webinars the company can hold on Tuesdays and Thursdays to make the highest weekly profit without interfering with consultations, which are also scheduled for Tuesdays and Thursdays and use the same resources. Use Solver to find this information as follows: a. Use Total weekly profit as the objective cell in the Solver model, with the goal of determining the maximum value for that cell. b. Use the number of Tuesday and Thursday sessions for the five programs as the changing variable cells. c. Determine and enter the constraints based on the information provided in Table 3. d. Use Simplex LP as the solving method to find a global optimal solution. e. Save the Solver model below the Maximum weekly profit model label. f. Solve the model, keeping the Solver solution. Table 3: Solver Constraints Constraint Cell or Range Each webinar is scheduled at least once on Tuesday and once on Thursday B4:F5 Each Tuesday and…
