Third Class Lever Calculator

Dimensions

Enter your specific requirements and find an actuator which has enough force to lift your load. For our Second Class Lever, make sure your LI distance is greater than your LE distance. If your application has a greater LE than LI, check out our Second Class Lever Calculator.

Force Required

Based on your input, you will need an actuator that has at least 20lb's of force. This is because your actuator is 2 times closer to the pivot than the load is.

Force Required

Based on your input, you will need an actuator that has at least 20lb's of force. This is because your actuator is 2 times closer to the pivot than the load is.

In this example the Actuator is doing the pulling movement. If the actuator is placed under the lever then it will be doing the pushing where the force requirements are exactly the same. For more information on third class lever's, check out our blog post on them here.
