Question

What is the angular velocity (in rad/s) of a body rotating at N r.p.m.?

Answer 1

0.1047N

Step-by-step explanation:

To solve this problem we must remember the conversion factors, remembering that 1 revolution equals 2π radians and 1min equals 60s

`N(rev)/(min) (2\pi )/(1rev) (1min)/(60) =N(2\pi )/(60) =0.1047N`

in conclusion, to know how many rad / s an element rotates which is expressed in Rev / min we must only multiply by 0.1047
