A wide-flange beam (see figure) is subjected to a shear force V.
Using the following dimensions of the cross section, calculate the moment of inertia and then determine the following quantities.
b = 180 mm, t = 12 mm, h = 410 mm, h1 = 355 mm, V = 120 kN
Note: Disregard the fillets at the junctions of the web and flanges and determine all quantities, including the moment of inertia, by considering the cross section to consist of three rectangles.
(a) the maximum shear stress ????max (in MPa) in the web
(b) the minimum shear stress ????min (in MPa) in the web
(c) the average shear stress ????aver (obtained by dividing the shear force by the area of the web) and the ratio in MPa
