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

The structure shown below is made of 3 circular rods, each with a diameter of 1.0" and lengths as shown in
the diagram. Rod AB is aluminum (E = 10E6 psi) and rod BC is steel (E = 30E6 psi) and rod CD is brass (E =
15E6 psi). The structure is axially loaded as shown in the diagram. Determine the maximum stress and
its location and the change in length of the structure due to the applied loads. You may ignore the
flanges that connect the rods (considered rigid).
