Question

Calculate the moment of inertia of the stick about its center having a mass of 1.1 kg and length of 2.9 m.

(a) .66 kgm^2

(b) .77 kgm^2

(c) .88 kgm^2

(d) .47 kgm^2

The question was asked during an interview for a job.

Answer 1

Correct option is (b) .77 kgm^2

The best I can explain: The moment of inertia of the stick about its center can be calculated using the formula I=ML^2÷12. The mass of the stick about its center and length is given. I=(1.1)×.0833×(2.9)^2=.77 kgm^2. It depends upon the orientation of the rotational axis.
