A steel shaft shown in the Figure 4(G=80GPa) is solid from A to B and hollow from B to C, having an inner diameter of 30mm and outer diameter of 60mm. Calculate (i) The shear stress (CB&BA) (ii) The maximum shear stress developed in the shaft (max) (iii) The angle of twist (in degree )(C/B&B/A) Figure 4
