The Rankine's constant for a mild steel column with both ends hinged is

The Rankine's constant for a mild steel column with both ends hinged is Correct Answer $$\frac{1}{{7500}}$$

We have defined the term Rankine constant in the previous section while deriving the alternate form of the Rankine formula. The Rankine constant denoted by ? was given as
α=σc/π2E
This Rankine constant is different for various materials. The Rankine constant for some of the materials used in the construction of columns is given in the table below:
Materials Rankine Constant (α)
Wrought Iron 1/9000
Cast Iron 1/1600
Mild Steel 1/7500
Strong Timber 1/750
