Reference no: EM13552436

Mounted on a low mass rod of length 0.44 m are four balls. Two balls each of mass 0.89kg, are mounted at opposite ends of the rod. Two other balls, each of mass 0.38 are each mounted a distance 0.11 m from the center of the rod. The rod rotates on an axle through the center of the rod perpendicular to the rod, and it takes 1.0 secs to make one full rotation.

(a) What is the moment of inertia of the device about its center?

(b) What is the angular speed of the rotating device?
