Question

Define 'Radius of Gyration'. Derive an expression for it.

Answer 1

RADIUS OF GYRATION :

• It is defined as the radius of a ring having the same moment of inertia (along geometric axis) as that of another body along a particular axis.

Now, let's see the derivation :

• Let the moment of inertia of a particular body along a given axis be I .

• And the radius of gyration be R :

So, we can say :

$m{R}^{2} = I$

$\implies {R}^{2} = \dfrac{ I}{m}$

$\implies R = \sqrt{\dfrac{ I}{m}}$

So, the radius of gyration along that axis will be √(I/m)
