Aditi Verma 8 years ago

radius of gyration:it is defined as the distance from the axis of rotation where whole mass of a body is supposed to be concentrated. its expression: MK^2=m1r1 +m2r2+m3r3 K^2=m1r1+m2r2+m3r3/M suppose that m1=m2=m3=m then, K^2=m(r1+r2+r3)/M K^2=n×m(r1+r2+r3)/M×n K^2=M(r1+r2+r3)/Mn K^2=r1+r2+r3/n K=√r1+r2+r3/n where K is radius of gyration.
