2. (25 pts) The frame shown below is supported by pins at C and D. A weight of 80 lb is suspended by a rope that passes over the frictionless pulley and attaches horizontally to member BD (0.5 ft above point B, as shown). a. Set up the free body diagrams of the pulley and members ABC and BD. Properly label your free body diagrams. b. Set up the equilibrium equations corresponding to your free body diagrams, ensuring that you have enough equations to solve for the total number of unknowns in your free body diagrams. Box your equations. You do not need to solve the equations. 0.5 ft 80 lb D B C 6 ft 9 ft 3 ft

Step 1

Free Body Diagram of the Pulley: The pulley is subjected to three forces: 1. The tension in the rope pulling downwards, equal to the weight of the suspended object (80 lb). 2. The tension in the rope pulling horizontally to the right, also equal to 80 lb since Show more…
