Consider that w $=600$ N$/$m$.$

Find: the internal force in member EF $($specify whether your reported force is tensile or compressive$),$ and the reactions in pin D $($specify whether your reported reaction forces are given concerning member AD or DC$).$ Answer should be : $=5\mathrm{.}06$ kN $($compression$),=1\mathrm{.}35$ kN and $=0$ kN $($with respect to the FBD of member AD$)$
