Actual Mechanical Advantage (AMA)

--

Where:
AMA = Output Force / Input Force
AMA represents how much a machine multiplies the force applied to it.

Calculation Formula

AMA = Fout / Fin

Where:
Fin = Input Force
Fout = Output Force
AMA = Actual Mechanical Advantage

What is Actual Mechanical Advantage (AMA)?

Actual Mechanical Advantage (AMA) measures how much a machine multiplies the force applied to it. It's calculated by dividing the output force by the input force.

How to Use This Calculator

  1. Enter the input force (the force you apply to the machine) in newtons (N).
  2. Enter the output force (the force the machine produces) in newtons (N).
  3. Click the "Calculate" button to compute the AMA.
  4. The calculator will display the AMA value and show the formula used.

Example

Suppose you apply a force of 50 N to a lever, and it produces an output force of 200 N. The AMA would be:

AMA = 200 N / 50 N = 4

This means the lever multiplies your input force by 4 times.

Important Notes

  • AMA can be less than the theoretical mechanical advantage (TMA) due to friction and other efficiency losses.
  • The input force must be greater than zero.
  • The output force cannot be negative.
  • Machines that increase force (like levers) typically have AMA greater than 1.
