Two shafts are connected end to end by means of a flanged bolt coupling as shown. The maximum shear stress is limited to 50 MPa in the shafts and 20 MPa in the bolts. If one shaft is solid of 100 mm diameter and the other is hollow of 120 mm external diameter, calculate the bolt diameter so that both shafts and the coupling are all equally strong in torsion. 120 mm 100 mm 200 250 mm mm Solid Hollow Flanged Bolt Coupling 24.17 mm B 27.14 mm C 21.74 mm D 24.71 mm
