balancing, Mechanical Engineering

A shaft carries three pulleys A,B and C. the pulleys B and C being 1.2m and 2.1m from A. the pulleys are out of balance to the extent of 0.03, 0.05 and 0.04kg.m respectively and are keyed to the shaft sa as to give static balance. find the relative angular positions of the radii which define unbalance. if the shaft is supported in bearings 1.8m apart, find the dynamic loading on each bearing when the shaft rotate at 300rpm.
