Main Question or Discussion Point

Here is my question that I havent been able to solve.
What would the torque ratio be for a set of gears with a gear ratio of 3.2:1?
And how did you come up with the answer?

If you apply a torque to a set of gears how does the gear ratio effect that?

If the gear ratio is 3.2:1, then the torque ratio is 1:3.2. The output shaft will have 3.2 times the torque of the input shaft if the input shaft rotates 3.2 times every time the output shaft rotates 1 time. Power remains the same except for drivetrain losses.
