A 41.8 N force is applied to the outer edge of a door of width d = 2.88 m.
(a) Find the torque when the force acts perpendicular to the door.
(b) Find the torque when the force acts at an angle of θ = 15.0° with respect to the door surface.
(c) Find the torque when the line of action of the force passes through the axis of the door hinges.
