$4$ identical hollow cylindrical columns of mild steel support a big structure of mass $\SI{50000}{\kilo\gram}$ . The inner and outer radii of each column are $\SI{30}{\centi\meter}$ and $\SI{60}{\centi\meter}$ respectively.
If the load distribution is uniform throughout, the total compressional strain acting on the cylindrical columns comes out to be $y \times 10^{-7}$ , where $y$ is a real number. Round off $y$ to the nearest integer and input it as your answer.
Details and Assumptions:
Young's Modulus of the mild steel \(Y_s = \SI{2.0 \times 10^{11}} { \newton \per \meter \squared}\).
Acceleration due to gravity $g = \SI{9.8}{\meter\per\second\squared}$ .
