Question

The engine of an old car is pulled out by a hoist. The hoist arm is 1.30 m long with a 200 kg engine attached at the end. A hydraulic piston pushing vertically upward 0.300 m from the pivot point keeps the hoist arm at a 22.0° angle. a) Draw the free body diagram for the hoist arm. b) Solve for the force from the piston. c) Solve for the reactions at the pin of the hoist arm. 22° 2.00 FBD IFY Er 2.00 3.00 1.00 1.00 1.00 reaction Units Total 10.0
