Calculate the design moment strength of a reinforced concrete beam 200 mm x 460 mm if at failure the concrete compression strain is 0.003 and the tensile steel strain is 0.005.  The flexure bars are 16 mm in diameter enclosed by 10 mm stirrups. Use f'c = 22 MPa and fy = 420 MPa.  Express your answer as a whole number in the unit of kN.m.

A composite shaft is made by slipping a bronze tube of 3.8-in. outer diameter and 2.5-in. inner diameter over a solid steel shaft of the same length and 2.5-in. diameter. The two components are then fastened rigidly together at their ends. What is the largest torque that can be carried by the composite shaft if the working shear stresses are 10 ksi for bronze and 14 ksi for the steel? For bronze, G = 6 x 10⁰ psi, and for steel, G = 12 x 10° psi.
