A solid circular shaft of 100 mm diameter is subjected to a bending moment M and twisting moment T. The magnitude of maximum principal stress developed is 100 bending stress TEXT OF T MPa. The maximum developed due to M alone is equal to maximum shear stress due to T alone. The torsion T on the shaft is (a) 12.13 N-m (c) 3 N-m (b) 6 N-m 15tdien 10 (d) 2 N-m
