Torque
Torque measures force applied during rotation: τ = rF. Torque (τ, the Greek letter tau) = the radius of the lever arm (r) multiplied by the force (F) applied. Radius is measured from the center of rotation or fulcrum to the point at which the perpendicular force is being applied. The resulting unit for torque is newton-meter (N-m) or foot-pound (ft-lb).
If A = 1 ft. and the green box weighs 35 lbs. what is the torque acting on the A side of this lever?
| 35 ft⋅lb | |
| 8 ft⋅lb | |
| 140 ft⋅lb | |
| 0 ft⋅lb |
