A 480-N uniform rectangular sign 4.00 m wide and 3.00 m high is suspended from a horizontal, 6.00-m-long, uniform, 110-N rod as indicated in the figure below. The left end of the rod is supported by a hinge and the right end is supported by a thin cable making a 30.0° angle with the vertical. (Assume the cable is connected to the very end of the 6.00-m-long rod, and that there are 2.00 m separating the wall from the sign.)
The figure shows a setup where when the member AB is horizontal and the unstretched aluminum bar length 2 m is attached to end D, the steel bar A has a gap of 3 mm with the support at Cas shown by A in the figure. At that point the system is deformed and the steel bar is attached to the support C. After this is done and all external forces are removed compute (a) the forces in both the steel and the aluminum bars. 0.75 m 1.5 m Steel A = 250 mm?

Problem 1: Three vertical posts AD, BE, and CF are held between two horizontal rigid plates. Posts AD and CF are made of steel (Es = 200 GPa) and have cross sectional areas of 1000 mm² each. Post BE is made of aluminum (Ea = 73.1 GPa) and has a cross sectional area of 1500 mm². Initially, there is a small gap of 0.1 mm between BE and the top horizontal plate. Then a vertical force of P = 410 kN is applied, which is more than sufficient to close the gap completely. D -0.5 m B E -0.5 m- 0.4 m F Determine the normal stresses in posts AD, BE, and CF (both magnitude and sign).
