If I have a meter stick and placed it on a pivot point at L/3 from the left end of the stick. Then I put 6 washers( the weight is not required for this problem, we will use the amount of washers) 30cm left of the pivot point to balance the meter stick. (The distance from the pivot point to the center of the meter stick is 16cm) 1-Sketch a force diagram. Including r vectors for all the forces that contribute a torque. 2-Use the force diagram to write a net force equation. 3-Solve the net force equation to find the weight of the meter stick, in washer unit. (Not necessary to convert to Newtons)

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.
