QB4 BENDING STRESS The beam is loaded by one couple at each of its ends, the beam cross-section shown below (Figure QB4). Determine: a) The position of the horizontal neutral axis. b) The second moment of area of the section about the horizontal neutral axis. c) The values of the maximum tensile stress and the maximum compressive stress in the beam if it supports a maximum bending moment of 1200x10°N.mm and the base face is in tension. 150mm 50mm 250mm 50mm 50mm 150mm Fig QB4 [8 marks] (a)3 marks b) 3marks c) 2marks]
