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:**

- First, determine the maximum load on the pulley (N). In this example, the maximum load on the pulley (N) is measured to be 40.
- Next, determine the radius of the pulley (m). For this problem, the radius of the pulley (m) is calculated to be 40.
- 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)
