The empirical formula defines the force per unit area that causes a maximum stress in a column given the slenderness ratio. Determine the ratio P/A using Bisection method if the slenderness ratio Le/r = 100, E = 20000 kPa, ec/r = 0.2, and a stress Om = 250 kPa. Fill up the table of results (Hint: let x = P/A then substitute the highlighted numeric values to the formula. Do not worry about the units, it will cancel out to leave you with the ratio).
