Question

A flywheel rotates at a constant speed of 3000 r.p.m. The angle described by the shaft
in one second is ?

​

Answer 1

see the attachment :-

$x = 100\pi \: radian$

Answer 2

Answer:

Given, rotation speed of fly-wheel, n=3000rpm/60 =50 rps

Now, the angular velocity ω is given by:

ω=2πn =2π(50)=100π rad/s

The angle described by the shaft is:

θ=ωt

So, for t=1 s,

θ=ω×1=100π rad  

This is your answer.

Hope this helps you!
