A simple beam of W 10 x 30 wide-flange cross section supports a uniform load of intensity q = 3.0 k/ft on a span of length L = 12 ft (see figure). The dimensions of the cross section are h = 10.5 in., b = 5.81 in., tf = 0.510 in., and tw = 0.300 in.
(a) Calculate the maximum shear stress Ï„max on cross section A-A located at distance d = 2.5 ft from the end of the beam.
(b) Calculate the shear stress Ï„ at point B on the cross section. Point B is located at a distance a = 1.5 in. from the edge of the lower flange.
