A 51.4 N force is applied to the outer edge of a door of width d = 2.72 m

Question

a) Find the torque when the force acts perpendicular to the door.
N · m

(b) Find the torque when the force acts at an angle of è = 11.5° with respect to the door surface.
N · m

(c) Find the torque when the line of action of the force passes through the axis of the door hinges.

Answer 1

torque=force*2.72 give torque about hinges.

b. torque=force*2.72*sin11.5

c. zero.
