Question 11 (12 points) Consider a two-stepped column, as shown in the figure below (figure NOT in scale). Assume that the first step has a square solid cross section of side a₁ and that the second step has a square solid cross section of side a2. If the ratio of the lengths (L1/L2) is equal to 7 and the ratio of the sides (a2/a1) is equal to 7, then what is the ratio (Utotal/U2) equal to, where U denotes the strain energy of an element and Utotal represents the total strain energy of the examined system?
