1 answer

The correct equation for calculating the mechanical advantage (MA) of a simple machine is:

MA = Δxi / Δxo

Where:

  • Δxi is the input distance (the distance over which the input force is applied).
  • Δxo is the output distance (the distance over which the output force is applied).

This relationship indicates the ratio of the input distance to the output distance, which effectively defines the mechanical advantage of the machine.
