Basic Torque Calculations

Torque (T) is shown as the product of the force (F) and the length (L).


Torque Evaluation

= 2F x L/2 (If the force is doubled, halving the length will develop the same torque.)

Torque Evaluation

= F/2 x 2L (If the force is halved, doubling the length will develop the same torque.)


Therefore, a longer lever will require less hand force to produce the same amount of torque.

T1 = F1 x L1 = 10 lbs x 2 ft = 20 ft·lbs
T2 = F2 x L2 = 20 lbs x 1 ft = 20 ft·lbs
T1 = T2
