Name____________________________ Practice Problems 1. The truss shown below has joints labeled 1-9 (be careful, the numbering system is a little confusing). Calculate the reactions at pins 1 and 9 and the forces in links 3-7, and 3-8. Remember that, when you have two pinned supports (as opposed to one pinned and one roller) you should use the top half of the truss. Much easier that way.

2. There are forces and a moment applied on the top of the I-beam. Translate that system of loads into an equivalent system at point B. Then do it again at point A.
3. There is a force, F , applied on the 6m-tall beam, OBD. F = 5kN j – 34kN i – 27kN k . Points A, B, and C have the following coordinates: (2, 0, 0) m, (0, 4.2, 0)m, and (0, 0, 5.7)m, respectively. Assume that point O is a ball-and-socket joint. What are the reactions at O and the tensions in the two cables?
