- Q1. Define slenderness ratio
- Ans.
The slenderness ratio is a measure of a structural member's susceptibility to buckling, defined as its effective length divided by its radius of gyration.
Slenderness ratio (λ) = Effective length (L) / Radius of gyration (r)
A higher slenderness ratio indicates a greater risk of buckling under load.
For example, a column with an effective length of 3000 mm and a radius of gyration of 100 mm has a slenderness ratio of 30.

- Q2. Define hook's law
- Ans.
Hooke's Law states that the force exerted by a spring is directly proportional to its extension or compression.
Hooke's Law formula: F = kx, where F is the force, k is the spring constant, and x is the displacement.
Example: If a spring has a spring constant of 200 N/m and is stretched by 0.1 m, the force exerted is 20 N.
It applies to elastic materials within their elastic limit, meaning they return to their original sha...
