Question 1 Report

A 20-toothed gear wheel drives a 60-toothed one. If the angular speed of the smaller wheel is 120 rev s-1, the angular speed of the larger wheel is

3 rev s-1

40 rev s-1

360 rev s-1

2400 rev s-1

Answer Details

$\frac{speed of driver}{speeder driven}$ = $\frac{no. of teeth of driver}{no. of teeth of driven}$

$\frac{120}{V}$ = $\frac{20}{60}$

v = 360 rev s-1
