Question

2. Figure 2 shows a stepped shaft ABCD fixed at A and loaded with a linearly distributed torque between B and C that varies from zero at B up to 2500 N mm/mm at C and a uniformly distributed torque of 2500 N mm/mm between C and D. AB is a tubular shaft of 100 mm outer diameter and 80 mm inner diameter whilst BCD is a solid circular shaft of 80 mm diameter. (a) Calculate the distribution of internal torques and stresses within the whole shaft. and draw the torsion graphs (b) Find the angular deflection of D relative to A. The material's shear modulus is 76.92 GPa. Ignore localised effects due to the support and the coupling at B. (20 marks) A 0 Nmm/mm 2500 Nmm/mm 2000 mm B 1500 mm D 1000 mm Figure 2 2500 Nmm/mm
