A simple beam with a rectangular cross-section ( width ,90 mm ; height, 300 mm ) carries a trapezoidally distributed load of 20 kN/m at A and 15 kN/m at B on a span of 4.2 m (see figure) . Find the principal stresses 0j and o, and the maximum shear stress Tmax at cross section 0.6 m from the left-hand support at 50 mm above the neutral axis. 20 kN/m 15 kN/m 300 mm B 90 mm |0.6 m 4.2 m
