A solid shaft shown is formed by two solid circular rods, AB and BC with a constant shear modulus G and polar moment of inertia JOAB and JoBC, and allowable stresses are given as AB all- 20 MPa, tBcal 40 MPa, 1) calculate the reaction force at A; 2) draw the internal torque diagram; 3) determine the minimum diameter for AB and BC TB =1200 N·m ?? 400 N-m AB 750 mm dBc 600 mm
