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.
