Question

8 8 2 124 2 2 t panela! @lb' = 92' Le

1. Calculate RL and RR:

2. Ignore CD and calculate tension in C1 and compression in A1. Draw a free body diagram of the left support to help define the problem.

3. Graphically check question 2:

4. Calculate distance y:

5. Using method of sections and ignoring CD, calculate tension in C3:

6. Assuming C3 is a 1(1/4)" rod, calculate the tension stress:

7. How do loading patterns and geometry violate the rules of an ideal truss?

8. Does the tension stress calculated in problem 6 exceed the elastic limit of 172,369 kPa?
