A simple beam of wide-flange cross section supports a uniform load of intensity q = 45 kN/m on a span of length L = 3 m. The dimensions of the cross section are h = 270 mm, b = 180 mm, and tf = 15 mm, tw = 12 mm, d = 0.8 m, and a = 60 mm. (a) Calculate the maximum shear stress omax on cross section A-A located at distance d = 0.6 m from the end of the beam. (b) Calculate the shear stress oB at point B on the cross section. Point B is located at a distance a = 60 mm from the edge of the lower flange. 2 2 A+ h 2 В

Question
Transcribed Image Text:A simple beam of wide-flange cross section supports a uniform load of intensity q = 45
kN/m on a span of length L = 3 m. The dimensions of the cross section are h = 270 mm,
b = 180 mm, and tf = 15 mm, tw = 12 mm, d = 0.8 m, and a = 60 mm.
(a) Calculate the maximum shear stress omax on cross section A-A located at distance d =
0.6 m from the end of the beam.
(b) Calculate the shear stress oB at point B on the cross section. Point B is located at a
distance a = 60 mm from the edge of the lower flange.
