The Mechanical Advantage Calculator helps determine how effectively a machine multiplies force. You can calculate mechanical advantage (MA) either using forces (Load ÷ Effort) or distances (Effort Arm ÷ Load Arm). A result greater than 1 means the machine increases your force, while less than 1 means it increases speed or distance. This tool is especially useful for studying levers, pulleys, and other simple machines in physics and engineering.
