Steel shaft can be produced as solid body or circular tube with circular tube. The shaft must bear a torque of 1200 Nm. Since the shear strength for the shaft material is 40 MPa, the maximum allowable unit torsion angle of the bar is 0.75 ^ 0 / m and the shear modulus of steel is G = 78 GPa; a) Find the required diameter d0 for a solid circle shaft. b) Find the required outside diameter d2 for a ring-section shaft whose thickness is one tenth of the outer diameter. c) Find the diameter ratio (d2 / d0 ratio) and weight ratio for ring cross section and solid section shafts
