A simply supported beam of hollow rectangular cross section is 100mm deep and 60mm wide with a wall thickness of 10mm. The beam has a span of 6m and carries a load as shown . Neglecting the weight of the beam draw a bending moment diagram and calculate the maximum bending moment. And determine the maximum bending stress in the material.

Part A The built-up beam in (Figure 1) is subjected to an internal moment of M = 50 kN · m Determine the amount of this internal moment resisted by plate A.

If Mz = 200 kip-ft, find the magnitude of the bending stress at a point H.  For the beam cross section, assume a = 7 in. b = 10 in. d = 26 in. r = 3.5 in.   The centroid of the cross section is located 11.96 in. below the uppermost surface of the beam.  The moment of inertia about the z axis is 12903 in.4.
