It is very easy to divide the section into half shift the load w (you can shift the load) to the right side and make a right angle triangle where perpendicular CE I assume make (w) and base as EB = cos60 and hypotenuse is BC= sin60 - w and for equilibrium, BC = sin60 - w =0 BC= +w/ (root3/2) = 2/w root3 assign is +ve so it is tensile.
