Concept explainers

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.
Question

1. A meterstick is able to rotate around its center. A perpendicular force of 2.0 N is applied at the 10 cmmark and a perpendicular force of 4.0 N is applied in the same direction at the 65 cm mark.

(a) What is the net torque acting on the meterstick?

(b) How much force and in which direction would have to be applied at the 80 cm mark for the nettorque to be zero?
