Analyzes forces and distances in a lever system based on the fulcrum position.

How To Use

How to use this calculator

Start with your values, or try a preset.

Step 1

Enter Force Applied (N), Distance from Fulcrum to Force (m), and Distance from Fulcrum to Load (m) in the units shown.

Step 2

Read Mechanical Advantage and Load Force (N) in the results panel. Results update as you change the inputs.

Step 3

Choose a preset to load an example, then adjust the values for your situation.
