Suppose I have a four foot high rectangular slab that weighs 100 pounds, and is hinged at the bottom. The slab is essentially a draw bridge. It is anchored at the by two chains on either side. A winch can lower and raise it. Suppose the slab is at 45 degree angle. How much torque is there in the chain? How about if it is at 60 degrees?.
