The horizontal rigid beam ABCD is supported by vertical bars BE and CF and is loaded by vertical forces P1 = 400 kN and P2 = 360 kN acting at points A and B, respectively (see
figure). Bars BE and CF are made of steel (E = 200 GPa) and have cross-sectional areas Ass = 11100 mm2 and A“: = 9280 mmz. The distances between various points on the
bars are shown in the figure. Knowing that the ultimate shearing stress is IOOMPs at ail
connections and the ultimate bearing stress in the bar vertical bars BE and CF is 200 MPa. Determine the vertical displacements 6,4 and 5d of points A and D, respectively.
Determine the minimum diameter of the pins at E. Side vide at point E
