Mechanical Advantage Calculator

Mechanical Advantage (MA):

Torque of the driven gear (T_output):

Torque of the driving gear (T_input):

How This Is Calculated

$$ MA = \frac{T_{output}}{T_{input}} $$ where:

MA = Mechanical Advantage (dimensionless)

T_output = Torque of the driven gear (Nm)

T_input = Torque of the driving gear (Nm)

Assumptions

There are no energy losses (the gears are ideal).
The gears are rigid and do not deform under load.
There is no slippage between the geat teeth.
Backlash is negligible.
