A uniform drawbridge must be held at a 37° angle above
the horizontal to allow ships to pass underneath. The drawbridge weighs
45,000 N and is 14.0 m long. A cable is connected 3.5 m from the
hinge where the bridge pivots (measured along the bridge) and pulls
horizontally on the bridge to hold it in place. What is the tension in
the cable?
