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 vertical bar consists of three prismatic segments A|, A" and A₃with cross-sectional areas of 6000 mm", 5000 mm' and 4000 mm' respectively. The bar is made of steel with E = 200 GPa. Calculate the displacements at points B. D,and E. Ignore the weight of the bar.
