Knowing the portion of the link BD has a uniform cross-sectional area of 800mm^2, determine the magnitude of the load P for which the normal stress in that portion of BD is 50 Mpa. (Hint draw a free body diagram of the link ABC)

sorry for the paint sketch I don't have a scanner, anyway I approached the problem as σ = F/A and we already have σ and A so I rearranged the problem as σ*A=F which came out to 40000N or 40Kn I'm not sure as to where to go from here or if I am going down the right track any help is appreciated thanks!
