Document Summary
Eight series: questions on torque and equilibrium: trap door, of length and width 1. 65 m, is held open at an angle of 65. 0o with respect to the floor. A rope is attached to the raised edge of the door and fastened to the wall behind the door in such a position that the rope pulls perpendicularly to the trap door. If the mass of the trap the trap door is 16. 8 kg, what is the torque exerted on the trap door by the rope: a rod is being used as a lever as shown. The fulcrum is 1. 2 m from the load and 2. 4 m from the applied force. If the mass of the load is 20. 0 kg, what force must be applied to lift the load: a weight of 1200 n rests on a lever at a point 0. 50 m from a support.
