Concept explainers

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.

Question

A bar AB having a length L and axial rigidity EA is fixed at end A (see figure).At the other end,a small gap of dimension sexists between the end of the bar and a rigid surface. A load Pacts on the bar at point C. which is two-thirds of the length from the fixed end.

IF the support reactions produced by load P are to be equal in magnitude, what should be the size

of the gap?
