Q407
The Rankine's constant for a mild steel column with both ends hinged is
A.
B.
C.
Answer
D.
Answer: Option C
Solution
Answer: Option C
Solution:
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 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 |
