If a mass whose moment of inertia is Ic/3 is placed at the free end and the constraint is assumed to be of negligible mass, then the kinetic energy is ______

(a) 1/6 Icω^2

(b) 1/2Icω^2

(c) 1/3Icω^2

(d) 1/12Icω^2

I had been asked this question in an online quiz.

The query is from Effect of Inertia of the Constraint on Torsional Vibrations in division Torsional Vibrations of Machine Dynamics

Right choice is (a) 1/6 Icω^2

The best I can explain: Kinetic energy is given by the equation

0.5Iω^2

inserting Ic/3 in place of I will give kinetic energy as

1/6 Icω^2.
