Question

( e ). When design for column under compressive loading, based on the slenderness ratio, either
Johnson's parabola or Euler's equation should be used. What is the tangency point separating
those two formulas in (L_e / ρ, Scr) coordinates? Here Scr is Pcr/A, Le is the equivalent length of the
column, and ρ is the radius of gyration of the cross-section, respectively.
