AW360 x 72 standard steel shape is used to support the loads shown on the beam in Figure A. The shape is oriented so that bending occurs about the weak axis as shown in Figure B. Assume P = 5.7 kN, w = 15.6 kN/m, M = 44 kN-m, and a = 1.45 m. Consider the entire 5.80m length of the beam and determine: (a) the maximum tensile bending stress at any location along the beam, and (b) the maximum compressive bending stress at any location along the beam.
