Find the shear flow distribution in the rectangular thin$-$walled section shown. Hence, find the

magnitude and location of the maximum shearing stress. All wall thickness $=0\mathrm{.}1"($inch$).$ If a wing $z-$flange is made of the shown cross section, with uniform thickness of $0\mathrm{.}1$ in$.$ The

flange is subjected to a vertical shear of $100$ lb and a horizontal shear of $50$ lb acting at the

centroid. Calculate the shear flow in the flange.

Solution:

$1$ in
