In the problem that was just solved $($figure

shown below$),$ with a negative applied moment

of $4$ kip.ft$,$ centroid at $3\mathrm{.}4$ in from the top and

moment of inertia equal to $91\mathrm{.}73i{n}^4,$ how much

is the bending stress at point $C,$ i$.$e$.,$ right where

the vertical wedge connects to the top

horizontal flange?
