University of California, San Diego, Department of Bioengineering BE 109: Statics and dynamics Issued: 01/26/05 (Tuesday) Homework Set 3 Due: 02/02/05 (Tuesday) Exercise 1 . A 32-lb motor is mounted on the floor. Find the resultant of the weight and the forces exerted on the belt, and determine where the line of action of the resultant intersects the floor. 60 lb 140 lb Exercise 2. Rod AB is acted upon by a couple M and two forces, each of magnitude P. a) Derive and equation in θ , P, M, and l which must be satisfied when the rod is in equilibrium. b) Determine the values of θ corresponding equilibrium when M = 150 lb-in., P = 20 lb, and l = 6 in.
