3. A solid steel shaft of 55 mm diameter and 0.85 m in length is subject to a torque of 1300 Nm. Calculate the maximum shear stress and the angle of twist.Shear modulus Gsteel = 90 GN/m2. A hollow steel shaft, 0.85 m in length, with 55 mm external and 35 mm internal diameter is subject to a torque of 1300 Nm. Calculate the maximum shear stress and the angle of twist. Shear modulus Gsteel = 90 GN/m2. An output shaft in machine is subjected to a torque of 500 Nm. What would the angle of twist be in the if it was 30mm solid or 30 mm hollow with a wall thickness of 3mm. Assume the material has a rigidity (G) of 70GPa Total:
