Answer:
The correct Euler’s bulking load ratio is . Option iv) is correct.
Explanation:
- Column tends to get buckle at the buckling load.
- Buckling load depends on end conditions whether they are fixed, free, or hinged.
The formula for buckling load is given by:
where, is Elasticity Young's modulus.
is the moment of inertia.
is effective length.
Step 1:
When both ends are fixed then
Substituting in the above formula we get:
When one end is free other fixed then
Step 2:
So, the required Euler’s bulking load ratio is .
Option iv) is correct.
