Question $14$

W$254$ x $33$ wide$-$flange beam is loaded and supported as shown below. At section A$-$A of the beam, determine the shear stress at point $"$a$"$ on the top surface of the flange.

For a W$25433$ section:

$I=49\mathrm{.}1({10}^6)m{m}^4,d=258mm,w_f=146mm,t_f=9\mathrm{.}1mm,t_w=6\mathrm{.}1mm$

$0$

$8\mathrm{.}83$

$10\mathrm{.}94$

$4\mathrm{.}56$
