At point K, Q is the momentof areas (3), (4), and (5) about the z centroidal axis:QK= 2[(3 mm)(7 mm)(8.5 mm)]+ (56 mm)(3 mm)(13.5 mm) = 2,625 mm33 mm 20 mm 3 mm56 mmy3 mmThe shear stress acting at K is3VQK(2,000 N)(2,625 mm )τ K = = = 9.92 MPa Ans.4It (88,200 mm )(6 mm)z(c) Maximum Horizontal Shear StressThe maximum value of Q corresponds to an area that begins at, and extendsaway from, the neutral axis. For this location, however, the words extendsaway from the neutral axis can mean either the area above or the area belowthe neutral axis. The value obtained for Q is the same in either case. For thedouble-tee cross section, the calculation of Q is somewhat simpler if weconsider the highlighted area below the neutral axis. In that case,30 mmz(6) (7)3 mm 20 mm 3 mm15 mm42 mmQ = 2[(3 mm)(30 mm)(15 mm)] = 2,700 mmmaxThe maximum horizontal shear stress in the double-tee shape is then3VQmax(2,000 N)(2,700 mm )τ max = = = 10.20 MPa Ans.4It (88,200 mm )(6 mm)z3mecmoviesExAmpLESm9.4 Determine the shear stress at points H and K for asimply supported beam that consists of the WT265 × 37standard steel shape shown.m9.5 Determine the distribution of shear stresses producedin a tee shape.342
