The Rankine's constant for a mild steel column with both ends hinged is
A. $$\frac{1}{{750}}$$
B. $$\frac{1}{{1600}}$$
C. $$\frac{1}{{7500}}$$
D. $$\frac{1}{{9000}}$$
Answer: Option C
Solution(By Examveda Team)
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 𝜶 was given asα=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 |
