Yes, I've tried it. But i didn't find the solution.
I'm confused with the element of volume and element of pyramid
"To find MI from the element, we need element of volume and element of MI, isn't it?"
But my lecture say this method is easy enough to solve.
And, actually i confused to find the element of volume and element of MI.
So, in your opinion, this is not solvable?
Homework Statement
Can i use "pyramid" method to derive the equation of Moment Inertia solid sphere?
The pyramid is such we slice a watermelon.
Sorry for my bad english.
Regards.
