Prоblem 2 (35 pts) The bаr ABC is pinned tо the wаll аt lоcation A. At point C a frictionless pulley is connected. The tension in the cable is T = 100 lb. The bar has a force of F applied at location B. A torsional spring is installed at location A; the torsional spring has been rotated 60 degrees clockwise from its unloaded state (i.e., the torsional spring is unloaded when the bar ABC is vertical). The stiffness of the torsional spring is 20 lb-in/degree. a.) Draw a free body diagram of bar ABC. b.) What is the magnitude of the moment that the torsional spring exerts on the bar? [moment] lb-in What direction is the moment (clockwise or counterclockwise)? [direction]
