TAM 211/210 BL1 Fall, 2004 Name: Practice Exam 2 Section: To receive full credit you must show all your work 2. The uniform block has known weight W. It rests on two ball and socket joints at two of its base corners as shown, and it is held up by a cable. It is in equilibrium. Draw a free body diagram for the block (10 points) What is the tension in the cable? (15 points) (For extra practice, assume the ball and socket joint at the origin has only reactions in the x and z direction, not the y-direction, while the other ball and socket joint has reactions in all three

The bars are pinned to the other objects and the walls using frictionless pins. The rope, bars, and pulley are all massless. The weight of the block is a known W. The system is in equilibrium. Draw a free body diagram for the pulley alone, and each of the two bars alone (5 points each) and the pulley, the block, and the two bars assembled as shown below (without the wall and ceiling) (5 points). What is the reaction force at of the wall on bar 1 (10 points), and what is the force on bar 2 due to bar 1 where they are pinned? (20 points) W Bar 1 Bar 2 d d 2d 2d...
