Mark is trying to rescue Mary from a castle by climbing a uniform ladder that is 5 m long and weighs 180 N. Mark, who weighs 800 N, stops a third of the way up the ladder . The base of the ladder rets on a horizontal ground and leans in equilibrium against a vertical frictionless wall. The ladder makes an angle of 53.1 degrees with the horizontal, and forming a 3-4-5 right triangle. Find the force exerted by the ground at the base of the ladder

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.
