UCLA: MAE-101: Chatterjee: Fall, 2006: Final Examination: Page 2 Problem 1 ( 2 + 5 + 8 ) The 40-lb door is supported by hinges at A and B. The hinges do not exert couples on the door, and the hinge at B does not exert a force parallel to the hinge axis. The weight of the door acts at its midpoint. 1. How many equations of equilibrium are there in a 3-D problem. 2. Clearly draw the free body diagram for the door. Do no show reactions that are zero. 3. Determine the reactions at A and B.

UCLA: MAE-101: Chatterjee: Fall, 2006: Final Examination: Page 4 Figure 2: Belt Friction Figure 3: Journal Bearing Problem 2 ( 3 + 7 + 10 ) The 20-kg box A is held in equilibrium on the inclined surface by the force T acting on the rope. The coefficient of static friction between the box and the inclined surface is 0.1. 1. Draw the free body diagram of box A 2. The coefficient of static friction between the rope and cylinder is 0.05 (Figure 2). Determine the largest value of T that will not cause the box to slip up the inclined surface.
