Find the tooth loads and bearing reactions for the shaft shown in figure used to transmit power (70 HP from one point to another). All gears used are of 20° pressure angle with 8 module. Sketch the top and front views of the shaft with bearings, indicating the loads and reactions. Neglect frictional losses, and weights of gears.
Distances AB = 120 mm, BC = 400mm, CD = 125mm and an Input speed = 300 r.p.m.
