Mechanical Advantage vs Output Force (Load)
Mechanical Advantage
Mechanical advantage describes how much a simple machine multiplies the input force.
Formula
MA = F_output / F_input
An MA greater than 1 means the machine amplifies force; less than 1 means it amplifies distance/speed instead.
Example Calculation
A lever lifts a 500 N load with 100 N of effort.
- 01MA = F_output / F_input
- 02MA = 500 / 100
- 03MA = 5
