The rigid bar AOB is pinned at O and connected to aluminum and steel rods. If the bar is horizontal at a given temperature, determine the ratio of the areas of the two rods so that the bar will be horizontal at any temperature. Neglect the mass of the bar. -3m- * A Aluminum E = 70 GPa a = 23.0 x 10-6/1C L=8m 4 m FIG.P2.91 B Steel E = 200 GPa a = 11.7 x 10-6/ L=8m The rigid bar AOB is pinned at O and connected to aluminum and steel rods.
