Problem $2.$ For the Howe truss in figure:

$1)$ determine the reactions and the Shear and Moment diagrams

$2)$ Use Method of sections to calculate the maximum forces in the top chord and in the bottom chord

$3)$ Use Method of sections or Method of joints to calculate the maximum force in braces

$4)$ check relations: Fchord $=$ M$/$chords and Fdiag $=$ V$*$d$/$dy$.$ Explain any differences between your results

and the above relations.
