A simply supported tapered rectangular beam $($the height $h(x)$ is changing with $x$ from $h_e$ at $x=0$ to $h_m$ at the midpoint $x=\frac{l}{2}$ and back to $h_e$ at $x=l)$ is loaded with a load $q_a.($i$)$ Determine the location of the max stress due to bending. $($ii$)$ What would be the load $q_a$ that can cause a normal stress of ${}_a=50$MPa in the location defined in $($i$)?l=3(m),b=0\mathrm{.}1(m),h_e=0\mathrm{.}15(m),h_m=0\mathrm{.}3(m)$
