1.	Define and derive the term \'Radius of gyration\'.
Answer» The moment of inertia of the body isI=m1k1^2+m2k2^2+m3k3^2.... Of m1 =m2 =m3 ...mnI=k^2(nm)k^2 I=mk^2Radius of gyration ,k=√(I/m)<br>The radius of an imaginary circle where all the particles of a body are assumed to be distributed on a circumference is called radius of gyration.
