#2 Posted 8:08pm 17-04-09 Re: 17-04-09 Time for something interesting?sir body diagonal or the face diagonal??
There are two things you should never try to prove ...... the impossible and the obvious ;) |

#9 Posted 10:24am 18-04-09 Re: 17-04-09 Time for something interesting?bhiayya do u have ans for this q this one seems to be a supertoughie |

#10 Posted 10:29am 18-04-09 Re: 17-04-09 Time for something interesting?yes 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?

#11 Posted 10:34am 18-04-09 Re: 17-04-09 Time for something interesting?no dont think its possible that way as distance would vary for the parts of cross section |
|
#12 Posted 10:36am 18-04-09 Re: 17-04-09 Time for something interesting?yup that is true.. but I am banking on being able to find the MI of each of the cross sectional planes!

#13 Posted 9:45pm 19-04-09 Re: 17-04-09 Time for something interesting?yes 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 = Ma[p]2[/p]/6 the same !!
