Critical Slenderness Ratio for Aluminium Columns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Slenderness Ratio = sqrt(51000000/(Allowable Load/Section Area of Column))
λ = sqrt(51000000/(Q/A))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Slenderness Ratio - Slenderness Ratio is the ratio of the length of a column and the least radius of gyration of its cross section.
Allowable Load - (Measured in Newton) - The Allowable Load is the maximum working load that can be applied on the structure.
Section Area of Column - (Measured in Square Meter) - The Section Area of Column is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.

STEP 1: Convert Input(s) to Base Unit

Allowable Load: 633.213 Newton --> 633.213 Newton No Conversion Required
Section Area of Column: 52900 Square Millimeter --> 0.0529 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

λ = sqrt(51000000/(Q/A)) --> sqrt(51000000/(633.213/0.0529))

Evaluating ... ...

λ = 65.2736671949162

STEP 3: Convert Result to Output's Unit

65.2736671949162 --> No Conversion Required

FINAL ANSWER

65.2736671949162 ≈ 65.27367 <-- Slenderness Ratio

Critical Slenderness Ratio for Aluminium Columns Formula

LaTeX Go

Slenderness Ratio = sqrt(51000000/(Allowable Load/Section Area of Column))
λ = sqrt(51000000/(Q/A))

What is Slenderness Ratio?

It is defined as the effective length of the column and the least radius of gyration, the latter defined by the area of the cross-section of the column and is the second moment of the area of the cross-section.

What is the purpose of Slenderness Ratio?

It is used extensively for finding out the design load as well as in classifying various columns in short/intermediate/long. The slenderness ratio of a column gives an indication of buckling failure in the column. The more the slenderness ratio, more the tendency of a column to fail by buckling effect in that direction.
