Question
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 8.0 kg. What is the moment of inertia of this system about the axis of rotation?

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 8.0 kg. What is the moment of inertia of this system about the axis of rotation?Explanation / Answer
moment of inertia is
I = (8kg)(.3m)^2 + (2kg)(0.7m)^2 = 0.72 + 0.98 = 1.7 Kgm^2
