SECTION 8.4 Maximum Stresses in Beams 669 Problem 8.4-7 A beam of wide-flange cross section (see figure) has the following dimensions: b 5 in., t 0.5 in., h 12 in., and h 1 10.5 in. The beam is simply supported with span length L 10 ft and supports a uniform load q 6 k/ft. Calculate the principal stresses s 1 and s 2 and the maximum shear stress t max at a cross section located 3 ft from the left-hand support at each of the following locations: (a) the bottom of the beam, (b) the bottom of the web, and (c) the neutral axis. 23.17 MPa t xy VQ It (60 kN)(420.5 * 10 3 mm 3 ) (108.89 * 10 6 mm 4 )(10 mm) Pure shear: s 1 23.2 MPa, s 2 23.2 MPa t max 23.2 MPa K ; Solution 8.4-7 Simply supported beam q 6.0 k/ft L 10 ft 120 in. c 3ft 36in.
