Using the method of superposition, predict the maximum allowable distributed load of w if reactions at the mid support can not exceed $155kN.$ Assume that $L=80m.,$ the beam cross$-$section is $ab$ which $a=50mm$ and $b=90mm$ the wood has a modulus of elasticity $(E)$ of $200$GPa. predict the reactions at the corner support based on your previous answer.

Name at least $3$ undesirable secondary effects of excessive beam deflection that you observe in picture above.

Share at least $2$ solutions to prevent the issue. $(5$ points$)$
