Question

5. Test by the method of dimensions the validity of the
2π where is the time period of torsional oscillation of body of moment of inertia I about the axis of rotation and k is the torque per unit radian twist due to torsional reaction of the suspension.
equation t = 2r √I/k

Answer 1

Answer:

The length between the point of rotation and the center of mass is L. The period of a torsional pendulum T=2π√Iκ T = 2 π I κ can be found if the moment of inertia and torsion constant are known.
