Column Slenderness Ratio for Critical Buckling Load Solution

Follow our step by step solution on how to calculate Column Slenderness Ratio for Critical Buckling Load?

FIRST Step Consider the formula

Lcr ratio = \sqrt{\frac{A \cdot π^{2} \cdot E}{P cr}}

Next Step Substitute values of Variables

∴

Lcr ratio = \sqrt{\frac{0.0688m² \cdot π^{2} \cdot 2E+11N/m²}{5304.912kN}}

Next Step Substitute values of Constants

∴

Lcr ratio = \sqrt{\frac{0.0688m² \cdot {3.1416}^{2} \cdot 2E+11N/m²}{5304.912kN}}

Next Step Convert Units

∴

Lcr ratio = \sqrt{\frac{0.0688m² \cdot {3.1416}^{2} \cdot 2E+11Pa}{5.3E+6N}}

Next Step Prepare to Evaluate

∴

Lcr ratio = \sqrt{\frac{0.0688 \cdot {3.1416}^{2} \cdot 2E+11}{5.3E+6}}

Next Step Evaluate

∴

Lcr ratio = 160.000005513163

LAST Step Rounding Answer

∴

Lcr ratio = 160
