and CF and is loaded by vertical forces P1 = 400 kN and P2 = 360 kN
acting at points A and D, respectively (see figure). Bars BE and CF
are made of steel (E = 200 GPa) and have cross-sectional areas ABE
= 11,100 mm2 and ACF = 9,280 mm2. The distances between various
points on the bars are shown in the figure.
Determine the vertical displacements δA and δD of points A and D,
respectively.

δ(BE) is 0.4mm, δ(CF) is 0.6mm but i don't know
why δ(A) ->δ(BE)->δ(CF)-> δ(D) is linearly
