BY THE WAY ITS NOT A M.O.I QUESTION
IT IS A 3 D QUESTION
formulae yaad karne hai abhi
kal tak kar doonga isko
9bhiayya do u have ans for this q
this one seems to be a supertoughie
62yes celestine.. This one is a super toughie.
It just came to my mind when I was sitting and I gave it..
But I think we can manage it by taking cross sections perpendicular to the diagonal?
can we?
9no dont think its possible that way as distance would vary for the parts of cross section
62yup that is true.. but I am banking on being able to find the MI of each of the cross sectional planes!
1yes this is tough ...
I learnt some more on moment of inertia and came to know about tensors ...
then actually it becomes very straightforward ..
we get MOI = Ma2/6 the same !!
