Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

5. A long slender column ABC is pinned at ends A and C and compressed by an axial force P (see figure below). At the midpoint B, lateral support is provided to prevent deflection in the plane of the figure. The column is a steel wide-flange section with E= 200 GPa.
