Question

Calculate the angular speed of the flywheel making 200 revolution per minute

Answer 1

Number of revolutions made by the flywheel = 200

Time taken to make 200 revolutions by the flywheel = 1 minute = 60 seconds

Let the frequency of the flywheel be f.

$f = \frac{200}{60}$

f = 3.33 Hz

Angular speed = 2$\pi$f

Angular speed = 2 × 3.14 × 3.33

Angular speed = 20.91 rad/sec

Hence, the angular speed of the flywheel is 20.91 rad/sec
