Unformatted text preview: Statics Exam 1 — Fall 2008 Name 1. (33 points) Two control rods are attached at A to lever AB. Using trigonometry and knowing that the force in the right—hand rod is F2 = 20 1b, determine (a) the required force F1 in the left-hand rod if the resultant R of the forces exerted by the rods on the lever is to be vertical, ([3) the corresponding magnitude of R. - - r \ a) H‘ C o I . :f‘B 2. (33 points) The support assemny shown is bolted in place at B, C, and D and supports a downward force P at A. Knowing that the forces in members AB, AC, and AD are directed along the respective members and that P = 45 1b, determine the forces in the members. {it :9 3. (33 points) Determine the moment about the origin 0 of the force F = (7.5 N)i + (3 N)j — (4.5 N)k which acts at a point A. Assume that the position vector of A is r = w~05 m)i + (3 m)j + (1.5 n1)k, ...
