Calculate the gear ratio between driver and driven gears. Essential for designing transmission systems, robotics, and understanding torque multiplication.
It means the input gear turns 3 times for every 1 turn of the output gear. This triples the torque but reduces the speed by 3x.
The driver is the gear connected to the power source (motor). The driven gear is the one connected to the load (wheels/arm).
Ratio > 1 increases torque.
