A trap door, of length and width 1.85 m, is held open at an angle of 65.0° 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 door is 17.2 kg, what is the torque exerted on the trap door about the hinge by the rope? Enter a positive value if the torque is in counterclockwise direction and enter a negative value if the torque is in clockwise direction. ___N⋅m
