Question
The two pulleys having radii of 15 cm and 8 cm, respectively are connected by a belt as shown in the figure. The larger pulley rotates 25 times in 36 seconds . What is the frequency of rotation of the smaller pulley ?
Answers
the smaller wheel rotates 15/8 as fast as the larger wheel.
So, 15/8 * 25rev/36s = (15*25)/(8*36) = 375/288 rev/s
So, 15/8 * 25rev/36s = (15*25)/(8*36) = 375/288 rev/s
