Q$1(50$ marks$)$

$($a$)$ Find the reaction force at the roller support and use the Method of Joints to calculate the forces in all of the members from the left support up to and including members $A,B$ and C the above truss.

$($b$)$ Verify the forces in members A$,$ B and C only using the Method of Sections.

$($c$)$ Summarise your results on a sketch of the truss showing roller reaction force and those member forces calculated in $($a$)$ and $($b$).$

Use the standard arrow notation to indicate struts$/$ties$.$
