Exercise l$-$Given the structure represented in the figure with $M1=0\mathrm{.}50kNm$ and $M2=0\mathrm{.}50kNm($with the directions indicated in the figure$)$ and considering the data in the table $($see attached$)$ for an IPNI$20.$

$($a$)$ Determine the reactions in the apollos.

$($b$)$ Draw the diagrams of the traction$/$compression$,$ shear and bending moments of the structure

c$)$ Identify the section subject to the most unfavorable tension$/$compression of the Structure.

d$)$ Check the structure's resistance to traction$/$compression by calculating the safety coefficient, considering the following data:

Material: A$$o$,{}_c=250$MPa,${}_R=400$MPa,${}_c=145$Mpa,$E=200{10}^3$MPa,$v=0,23,G=77$GPa
