Enter the maximum load on the pulley (N) and the radius of the pulley (m) into the calculator to determine the Load Torque. 

Load Torque Formula

The following formula is used to calculate the Load Torque. 

LT = ML * RP

  • Where LT is the Load Torque (N-m)
  • ML is the maximum load on the pulley (N) 
  • RP is the radius of the pulley (m) 

How to Calculate Load Torque?

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

Example Problem #1:

  1. First, determine the maximum load on the pulley (N). In this example, the maximum load on the pulley (N) is measured to be 40.
  2. Next, determine the radius of the pulley (m). For this problem, the radius of the pulley (m) is calculated to be 40.
  3. Finally, calculate the Load Torque using the formula above: 

LT = ML * RP

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

LT = 40 * 40 = 1600 (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:

maximum load on the pulley (N) = 90

radius of the pulley (m) = 80

Entering these values yields:

LT = 90 * 80 = 2700 (N-m)
