For the $6kN$ load at Joint B:

Determine the member forces and normal stresses in members A$-$B and B$-$C$.$

Calculate the deflection of the tie A$-$B$.$

Determine the strain in the tie.

Check if the strength of the tie is sufficient if it is made of Grade S$355$JR steel with Minimum Yield Strength of $355$MPa and Ultimate Strength of $480$MPa.

If the connections at points $A,B$ and $C$ consist of a single bolt $($diameter $20$mm$),$ with $2$ plates on either side, calculate the shear stress in the bolt at point A$.($refer to Figure $3$ for detail$)$
