(Civil eng.)

a. Design, write, compile, and run a program that determines the stress on a steel I-beam having a rectangular moment of inertia of 21.4 in4, and a height of 6 inches, when a load of 700 lbs is placed 8 feet from the fixed end. The stress placed on the fixed end of a symmetrical steel I-beam, as shown in Figure, can be determined by this formula:

S is the stress in lbs/in2.

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

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

d is the distance in inches the load is placed from the fixed end of the beam (technically referred to as the “moment arm”).

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

---

b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the stress when the same load is placed at the end of an 8-foot wooden beam with a height of 4” and a rectangular moment of inertia of 10.67 in4.
