Formula:
The Slenderness Ratio (SR or λ) is a dimensionless quantity used in structural engineering to characterize the buckling susceptibility of a compression member. It is defined as:
SR = L / r
Where:
- L = Effective Length of the compression member
- r = Radius of Gyration of the cross-section
The Radius of Gyration (r) itself is calculated by:
r = √(I / A)
Where:
- I = Area Moment of Inertia of the cross-section
- A = Cross-sectional Area
Note: Ensure consistent units for L, I, and A for a correct dimensionless ratio.
