Wide-flange shape W 8 x 28
A wide-flange beam (see figure) having the cross section described below is subjected to a shear force V. using the dimensions of the cross section, calculate the moment of inertia and then determine the following quantities:
(a) The maximum shear stress Ï„max in the web.
(b) The minimum shear stress Ï„max in the web.
(c) The average shear stress Ï„aver (obtained by dividing the shear force by the area of the web) and the ratio Ï„max / Ï„aver.
(d) The shear force Vweb carried in the web and the ratio Vweb/V.
