PRACTICE / Torque

A couple turns without pushing

Two parallel forces of 15 N act in opposite directions on a plate. Their lines of action are 0.20 m apart.

Find the magnitude of the net torque.

Organize the givens & assumptions
  • F = 15 N
  • perpendicular separation = 0.20 m

Two equal opposite parallel forces on a rigid body; 0.20 m is perpendicular separation of their lines of action.
