Question: problem 31 the horizontal rigid beam abcd is supported by...

Question details

Problem 3-1 The horizontal rigid beam ABCD is supported by vertical bars BE and CF and is loaded by vertical forces P-400 kN and P- 200 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-10,000 mm and Acr -8,000 mm2. The distances between various points on the bars are shown in the figure. 15m-15m PI-400kN 24m P 200kN Determine the vertical displacements 6, and δο of points A and D, respectively
