How to Use the Pulley Calculator

To use the pulley calculator, simply enter the total load you need to lift and the number of pulleys being used in the system. After inputting this information, click the “Calculate” button to determine the amount of force needed in Newtons to lift the load with the specified number of pulleys.

How It Calculates the Results

The calculator uses the simple mechanical advantage formula Force = Load / Number of Pulleys. By dividing the load by the number of pulleys, the calculator provides the force needed for lifting that load using the pulley system. Mechanical advantage assumes ideal conditions with frictionless pulleys and weightless ropes.

Limitations

This calculator assumes an ideal mechanical system with no friction losses and weightless ropes. In realistic scenarios, actual force requirements may be higher due to these factors. Always ensure to account for safety factors and consult with an engineer for critical applications.
