A fly wheel of mass 4 kg has moment of ...

A fly wheel of mass 4 kg has moment of inertia `16 kg m^(2)`, then radius of gyration about the central axis perpendicular to its plane is

A

1m

B

2m

C

4m

D

16m

Text Solution

Verified by Experts

The correct Answer is:
B

`I = MK^(2)`
`K = sqrt((I)/(m)) = sqrt((16)/(4)) = sqrt(4) = 2`.
