Evening /sci/tizens,

I pose to you a question for only the best. Dont fail!

A rigid shaft, 3m long, is symmertically supported in bearings located 0.5m from each end. It carries pulleys of mass 20kg at each end, one of these pulleys having an eccentricity of 1.5mm and the other an eccentricity of 2.0mm. A third pulley, of mass 30kg and eccentricity 2.0mm, is positioned at the mid-span.

Determine the relative angular position of the centre of mass of each pulley.
