Rotational Motion Question 195

Question: The moment of inertia of a thin uniform rod of mass M and length L about an axis passing through its midpoint and perpendicular to its length isI0 . Its moment of inertia about an axis passing through one of its ends and perpendicular to its length is

Options:

A) I0+ML2/2

B) I0+ML2/4

C) I0+2ML2

D) I0+ML2

Show Answer

Answer:

Correct Answer: B

Solution:

[b] By theorem of parallel axes,

I=Icm+Md2

I=I0+M(L/2)2=I0+ML2/4
