A uniform drawbridge must be held at a 37.5 degree angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 4.20×104 N , is 12.0 m long, and pivots about a hinge at its lower end. A cable is connected 4.00m from the hinge, as measured along the bridge, and pulls horizontally on the bridge to hold it in place.

A. What is the tension in the cable?

B. Find the magnitude of the force the hinge exerts on the bridge.

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?
