Question $2$

A statically determinate three$-$hinged arch is shown below, $L=2m$ and $P=2kN.$ Compute the

support reactions and internal forces at Sections $C^{-}$and $C^{+}.$

$($All reaction force and internal force answers to be entered as absolute values.$)$

a$)$

Analyse the whole arch to determine the vertical reaction forces:
