A drawbridge has mass M and length L and is approximately uniform. It has a hinge at the right end, and is being pulled up via a cable (FT) that is pointed 45 degrees up from “to the right” and is connected at L/3 from the left end. Assume that the tension is just enough that there’s no normal force at the left end of the bridge. Draw a torque diagram for the bridge, with the hinge as the pivot point. Assume it is stationary and not accelerating.
