A bench is made by placing a 3.4 meter long plank on two legs, each 0.1 meters from one of the plank's ends. The plank has a mass of 10.5 kg. A 3.5 kg box is placed on the the plank, 1.42 meters from the right edge. Find the normal forces exerted by the two legs. What is the normal force exerted by the left leg? What is the normal force exerted by the right leg?

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.
