Question

A disk of mass 10kg oscillating about x and x ¹ axis in its plane if it's radius is 2m then, find frequency of its oscillations?

Answer 1

Answer:

300 rad\sec

Explanation:

Moment of inertia I=

2

mr

2

=

2

10×0.2

2

=0.2 kgm

2

Angular acceleration α=

I

τ

=

0.2

10

=50 rad/s

2

Initial angular velocity w

i

=0

Using w

f

=w

i

+αt

Or w

f

=0+50×6=300 rad/s

Answer 2

Answer:

300 rad/sec
