A uniform drawbridge must be held at a 38.5 ∘∘ angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 48000 NN, is 19.0 mm long, and pivots about a hinge at its lower end. A cable is connected 3.70 mm from the hinge, as measured along the bridge, and pulls horizontally on the bridge to hold it in place. C: Find the direction of the force the hinge exerts on the bridge. D: If the cable suddenly breaks, what is the initial angular acceleration of the bridge?
