A 23.0 kg ladder is laid up against a smooth vertical surface. Friction between the floor and the ladder keeps it from slipping. The angle between the floor and the ladder is = 56.0°. B 7. A The length of the ladder is L = 3.50 m and its mass is distributed uniformly. There is no friction along the wall (surface parallel to segment OB) but there is friction along the floor (surface parallel to segment AO). (a) What is the net torque about point A?

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
