Problem 1: A rigid plate must be supported by three steel bars with square cross section, as shown in the figure below. The Young Modulus for steel, Es, is 2.0 e5 Mpa. If yielding stress of steel A36 is 250 Mpa, and Factors of Safety, F.S, in tension and compression are 2 and 2.5 respectively. a) What is the required cross-sectional area for each of the bars? Round to half a centimeter. You decide up, down, or nearest. b) Find the final displacement of point D. (horizontal, vertical, total, angle) c) Determine displacement of Points A, B, and E, quantitively or qualitatively. (Extra point) Ignore buckling in compressive members. B 2m 4m 10kN/m C D 0.5m 0.5m F E G 0.5m
