The shaft ABCD is bearing torques at pully A, B, C, and D as shown in the figure. The magnitude of the torques on each pully and the shaft length are given. All shafts are made of a material with a modulus of rigidity of G = 80 GPa. The diameter of shafts (1) and (2) is d1 = d2 = 52 mm, and the diameter of shafts (3) and (4) is d3 = d4 = 58 mm. The bearings shown allow the shaft to turn freely.
