Mechanical Advantage Calculator

An online tool to calculate component forces in pulley systems

This tool has been set up to allow users to calculate the mechanical advantage of a pulley system, while taking into account friction of its various components.

Pendulum Fall Calculator

An online tool to calculate forces generated during a pendulum fall with midpoint anchor failure

About the calculator This calculator estimates the peak forces generated during a steep traverse fall, where a climber swings (pendulums) on a rope that may be redirected through an intermediate anchor.
