PROBLEM 1. (20 pts) 1a. (6 pts) Determine the moment of inertia with respect to x axis. You may use the formulas below: 1b. (14 pts) The loading of the beam is shown below i.(4 pts) Draw a free body diagram of the beam (replace the distributed load with a single concentrated load), then determine the reactions at support A and B. ii.(8 pts) Draw the shear and bending-moment diagrams for the beam. Explain how the changes occurs due to the external force or moment in the two diagrams (For example: an upward force (5 lb) moves the V diagram up by 5 lb). No credit will be received if you do not explain iii.(2 pts) Determine the maximum absolute values of the shear and bending moment. At what points or what sections do they occur?

PROBLEM 2. (20 pts) The Boom AED 4 m which is held by a ball-and socket joint at D and by two cables AB and AC. The load at point A is in the negative z direction and load at point E is in the positive y direction. a.(4 pts) Draw a free-body diagram for the boom AED. (Don’t forget the reactions) b.(4 pts) Express the tension in each cable in terms of a unit vector and its unknown magnitude. (i.e.
