Enter the lever force (N) and the distance from the lever force to the fulcrum (m) into the calculator to determine the Lever Torque. 

Lever Torque Formula

The following formula is used to calculate the Lever Torque. 

TL = LF * D

  • Where TL is the Lever Torque (N-m)
  • LF is the lever force (N) 
  • D is the distance from the lever force to the fulcrum (m) 

How to Calculate Lever Torque?

The following two example problems outline how to calculate the Lever Torque.

Example Problem #1:

  1. First, determine the lever force (N). In this example, the lever force (N) is measured to be 50.
  2. Next, determine the distance from the lever force to the fulcrum (m). For this problem, the distance from the lever force to the fulcrum (m) is calculated to be .75.
  3. Finally, calculate the Lever Torque using the formula above: 

TL = LF * D

Inserting the values from above and solving the equation with the imputed values gives: 

TL = 50 * .75 = 37.5 (N-m)


Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

lever force (N) = 75

distance from the lever force to the fulcrum (m) = .33

Entering these values yields:

TL = 75 * .33 = 25 (N-m)
