Rankine's Formula for Columns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rankine’s Critical Load = 1/(1/Euler’s Buckling Load+1/Ultimate Crushing Load for Columns)
P_r = 1/(1/P_E+1/P_cs)
This formula uses 3 Variables

Variables Used

Rankine’s Critical Load - (Measured in Newton) - The Rankine’s Critical Load is the axial load at which a perfectly straight column or structural member starts to bend.
Euler’s Buckling Load - (Measured in Newton) - The Euler’s Buckling Load is the axial load at which a perfectly straight column or structural member starts to bend.
Ultimate Crushing Load for Columns - (Measured in Newton) - The Ultimate Crushing Load for Columns is the ultimate load that column can bear before failure.

STEP 1: Convert Input(s) to Base Unit

Euler’s Buckling Load: 1491.407 Kilonewton --> 1491407 Newton (Check conversion here)
Ultimate Crushing Load for Columns: 520 Kilonewton --> 520000 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_r = 1/(1/P_E+1/P_cs) --> 1/(1/1491407+1/520000)

Evaluating ... ...

P_r = 385566.740097852

STEP 3: Convert Result to Output's Unit

385566.740097852 Newton -->385.566740097852 Kilonewton (Check conversion here)

FINAL ANSWER

385.566740097852 ≈ 385.5667 Kilonewton <-- Rankine’s Critical Load

What is Crippling Load?

The crippling load, or more frequently called load, is the load over which a column prefers to deform laterally rather than compressing itself. Buckling is not about going over the maximum compressive stress, it is rather about the structure finding a geometrically stable alternative to being compressed.

How to Calculate Rankine's Formula for Columns?

Rankine's Formula for Columns calculator uses Rankine’s Critical Load = 1/(1/Euler’s Buckling Load+1/Ultimate Crushing Load for Columns) to calculate the Rankine’s Critical Load, The Rankine's Formula for Columns formula is defined as a method to determine the crushing stress of a column, taking into account the external load and the internal resistance of the column, providing a reliable way to calculate the maximum stress a column can withstand before collapsing. Rankine’s Critical Load is denoted by P_r symbol.

How to calculate Rankine's Formula for Columns using this online calculator? To use this online calculator for Rankine's Formula for Columns, enter Euler’s Buckling Load (P_E) & Ultimate Crushing Load for Columns (P_cs) and hit the calculate button. Here is how the Rankine's Formula for Columns calculation can be explained with given input values -> 0.385567 = 1/(1/1491407+1/520000).
