Enter the effort force and lever force into the calculator to determine the pivot force.

Pivot Force Formula

The following equation is used to calculate the Pivot Force.

PF = LF + EF
  • Where PF is the pivot force (N)
  • LF is the lever force (N)
  • EF is the effort force (N)

To calculate the pivot force, sum the lever and effort forces together.

What is a Pivot Force?


A pivot force is the total force acting at the pivot point of a lever at equilibrium due to the effort and lever forces.

How to Calculate Pivot Force?

Example Problem:

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

First, determine the lever force. In this example, the lever force is found to be 10N.

Next, determine the effort force. For this problem, the effort force is found to be 13N.

Finally, calculate the Pivot Force using the formula above:

PF = LF + EF

PF = 13 + 10

PF = 23 N
