A horizontal nickel steel shaft shown in the below Figure rests on two bearings, A at the left and B at the right end and carries two gears C and D located at distances of 250 mm and 400 mm respectively from the centre line of the left and right bearings. The diameter of the gear C is 600 mm and that of gear D is 200 mm. The distance between the centre line of the bearings is 2400 mm. The shaft transmits 20 kW power at 120 r.p.m. The power is delivered to the shaft at gear C and is taken out at gear D in such a manner that the tooth force Fic of the gear C and FID of the gear D act vertically downwards. The gear C and D weighs 950 N and 350 N respectively. The combined shock and fatigue factors for bending and torsion may be taken as 1.5 and 1.2 respectively 1) Determine the reactions acting on the bearings A and B
