A horizontal shaft supported by bearings A and E. The distance between A and E is 7 m. The shaft carries three pulleys (B, C, and D) of mass 120, 140 and 40 kg at 2, 4, and 5.5 m respectively from bearing A. The centres of mass of these pulleys are at 4.5. 3.0, and 5.0 mm respectively from the shaft axis. The angular positions of masses D and C with respect to that in mass B if the shaft is in static balance is 135° and 200° anti-clockwise. The shaft rotates at 300 revolutions per minute (rpm). Determine the dynamic load (N) on each bearing. A horizontal shaft supported by bearings A and E. The distance between A and E is 7 m.
