$-$ Problem $1$

The beam is roller supported at $($B$)$ and pin supported at $($A$).$ For this beam, do the following:

$($i$)$ Determine the zero$-$force members $($without calculations$)$ of the truss

$($ii$)$ Calculate the truss member forces,

$($iii$)$ Determine the reaction forces and

$($iv$)$ Draw the axial force $[$N$],$ shear force $[$V$]$ and bending moment $[$M$]$ diagrams for the whole structure $($beam and truss$).$
