System Of Particles And Rotational Motion Ques 70
In a rectangle $A B C D$ ($B C=2 A B$). The moment of inertia is minimum along axis through [1993]
(a) $BC$
(b) $B D$
(c) $HF$
(d) $E G$
Show Answer
Answer:
Correct Answer: 70.(d)
Solution:
- (d) The M.I. is minimum about EG because mass distribution is at maximum distance from EG.
Among so many parallel axes, moment of inertia of the body is the minimum about an axis which is passing through the centre of mass of the body.
