The assembly shown consists of a light rigid bar AB, pinned at 0, that is attached to the steel and aluminum rods. In the position shown, bar AB is horizontal and there is a gap, A =7 mm, between the lower end of the steel rod and its pin support at C. The stress in the aluminum rod (in MPa) when the lower end of the steel rod is attached to its support is: Eal 70 GPa, Est 200 GPa. A= 240 mm2, As= 170 mm2. %3! 0.75 m 1.5 m
