STEP 0: Pre-Calculation Summary
Formula Used
Column Length = (((Distance of Deflection from End A^2)/2)-((Bending Moment in Column+(Axial Thrust*Deflection at Section of Column))/Load Intensity))*2/Distance of Deflection from End A
lcolumn = (((x^2)/2)-((Mb+(Paxial*δ))/qf))*2/x
This formula uses 6 Variables
Variables Used
Column Length - (Measured in Meter) - Column Length is the distance between two points where a column gets its fixity of support so its movement is restrained in all directions.
Distance of Deflection from End A - (Measured in Meter) - Distance of Deflection from End A is the distance at which the deflection occurs in a beam or column, measured from one end of the beam, designated as End A.
Bending Moment in Column - (Measured in Newton Meter) - Bending Moment in Column is the reaction induced in a column when an external force or moment is applied to the column, causing it to bend.
Axial Thrust - (Measured in Newton) - Axial Thrust is the force exerted along the axis of a shaft in mechanical systems. It occurs when there is an imbalance of forces that acts in the direction parallel to the axis of rotation.
Deflection at Section of Column - (Measured in Meter) - Deflection at Section of Column is the lateral displacement at the section of the column.
Load Intensity - (Measured in Pascal) - Load Intensity is the distribution of load over a certain area or length of a structural element.
STEP 1: Convert Input(s) to Base Unit
Distance of Deflection from End A: 35 Millimeter --> 0.035 Meter (Check conversion ​here)
Bending Moment in Column: 48 Newton Meter --> 48 Newton Meter No Conversion Required
Axial Thrust: 1500 Newton --> 1500 Newton No Conversion Required
Deflection at Section of Column: 12 Millimeter --> 0.012 Meter (Check conversion ​here)

What is Compressive Axial Load?

A Compressive Axial Load is a force applied along the axis of a structural element, such as a column, beam, or strut, which tends to shorten or compress the member. It is a type of load that acts uniformly in the same direction as the longitudinal axis of the element, resulting in compressive stresses throughout the material. This load causes the member to reduce in length, and if the load is high enough, it can lead to failure by crushing, buckling, or other modes of compressive failure.
