# An Effort is Applied on the Bigger Wheel of a Gear Having 32 Teeth. It is Used to Turn a Wheel of 8 Teeth. Where It is Used. - Physics

An effort is applied on the bigger wheel of a gear having 32 teeth. It is used to turn a wheel of 8 teeth. Where it is used.

#### Solution

The number of teeth in the driving wheel is nB = 32 and that in the driven wheel is nA = 8. Hence, this system is used to obtain the gain in speed

The Gain in speed  = n_B/n_A= 32/8 = 4
