A transmission shaft, supporting two pulleys A and B and mounted between two bearings C₁
and C₂
is shown in Fig. Power is transmitted from pulley A to B. The shaft  is made of plain carbon steel 45C8 (S_ut
= 600 and S_yt
= 380 N/mm²). The pulleys are keyed to the shaft. Determine the shaft diameter using the ASME code if, k_b=1.5 and k_t=1.0
