· A horizontal shaft AD supported in bearings at A and B and carrying pulleys at C and D is to transmit 75 kW at 500 r.p.m. from drive pulley D to off-take pulley C, as shown in Fig. 14.18. ? D D P1 A B T P2 600 600 300 64 Q Q2 All dimensions in mm. Fig. 14.18 Calculate the diameter of shaft. The data given is : P = 2 P2 (both horizontal), Q, = 2 Q2 (both vertical), radius of pulley C = 220 mm, radius of pulley D= 160 mm, allowable shear stress = 45 MPa.
