In a chain drive system the number of ______ between the driver and driven sprockets can be used to determine the sprocket ratio.

Explanation:
In a chain drive, the sprocket ratio is determined by the number of teeth on the driver and driven sprockets. The chain has a constant pitch, so one full turn of the driver advances the chain by a fixed amount per tooth. Therefore, the rotational speed relationship between the driver and driven depends only on how many teeth each sprocket has. More teeth on the driven sprocket relative to the driver yields a slower output speed and higher torque; fewer teeth yields a faster output speed. The other factors listed (chain links, chain pitch, sprocket material) do not determine the ratio.
