## Pulley Force Formula

The following equation is used to calculate the Pulley Force.

Fp = TF – GF

- Where Fp is the pulley force (N)
- TF is the force of tension from the pulley (N)
- GF is the gravitational force (N)

To calculate the pulley force, subtract the gravitation force from the tension force.

## What is a Pulley Force?

Definition:

A pulley force is a measure of the net force acting on an object that is being raised by a pulley. The pulley force is dependent on the tension force and the gravitational force.

## How to Calculate Pulley Force?

Example Problem:

The following example outlines the steps and information needed to calculate the Pulley Force.

First, determine the tension force. In this example, the tension force is measured to eb 100N.

Next, determine the gravitational force. This is calculated from the mass, and in this case, is found to be 75N.

Finally, calculate the pulley force using the formula above:

Fp = TF – GF

Fp = 100-75

Fp = 25N
