Question
A uniform drawbridge must be held at a 34.0 angle above the horizontal to allow ships to pass underneath. The drawbridge weighs 4.95×104 N , is 10.0 m long, and pivots about a hinge at its lower end. A cable is connected 3.95 m from the hinge, as measured along the bridge, and pulls horizontally on the bridge to hold it in place.
Part A
What is the tension in the cable? (N)
Part B
Find the magnitude of the force the hinge exerts on the bridge. (N)
Part C
Find the direction of the force the hinge exerts on the bridge. ( above the horizontal )
Part D
If the cable suddenly breaks, what is the initial angular acceleration of the bridge? (rad/s^2)
