Question

State an expression for the radius of gyration of a thin uniform disc about a

transverse axis passing through its circumference and parallel to its plane.​

Answer 1

Answer:

Answer

Correct option is

A

R/√2

Moment of Inertia of disc about center of mass is I=2mR2

Let a line parallel to axis at a distance d.

Radius of Gyration=R

Then, 2mR2=mR2

⇒R2=2R2

⇒R=2R
