Enter the mass of the objects at both ends of the beam into the calculator to determine the support force.

## Support Force Formula

The following equation is used to calculate the Support Force.

SF = (M1+M2)*g
• Where SF is the support force (N)
• M1 is the mass of object 1 (kg)
• M2 is the mass of object 2 (kg)
• g is the acceleration due to gravity (m/s^2)

To calculate a support force, add the masses at either end of the beam/lever and then multiply by the acceleration due to gravity.

## What is a Support Force?

Definition:

A support force measures the total force acting at the support or pivot point of a beam/lever system. Typically, this system is at equilibrium and has different masses at either end of the beam.

## How to Calculate Support Force?

Example Problem:

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

First, determine the mass of object 1. In this example, the mass of object 1 is found to be 30kg.

Next, determine the mass of object 2. For this problem, the mass of object 2 is found to be 10kg.

Finally, calculate the Support Force using the formula above:

SF = (M1+M2)*g

SF = (30+10)*9.81

SF = 392.4 N
