A tray rests on an extendible arm consisting of two steel tubes with two different outer diameters. The downward force at the tray center F0 = 1000 N. Determine the downward deflection of the tray center and the tilt angles of the tray about each coordinate axis. The wall thickness of both tubes is 4 mm. Take d1 = 40 mm, d2 = 34 mm, a = 500 mm, b = 300 mm, and Esteel = 200 GPa.
