Determine the moment of inertia of the composite area about the x axis. Set a = 670 mm , b = 240 mm , h = 130 mm , r = 85 mm . Express your answer with the appropriate units.

Problem # 9: Locate the centroid of the composite area shown. Then calculate the moment of inertia about the axes passing through the center of gravity ( that is the centroidal moment of inertia, Ixe and Iyc ) . 8 in. 3 in. 3 in. 2 in 4 in. 4 in -- 4 in -

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.
