Asked by Tyler

The drawing shows two blocks that are placed at the ends of a massless board. The board is balanced on a support that serves as an axis of rotation. The block on the left has a mass of 5.8 kg. What is the moment of inertia of this system about the axis of rotation?
Answered by bobpursley
you have three components, the two masses, each mr^2, and the board, 1/2 massboard*length^2
so add the three components.
and r= length/2 of course.
