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

As shown in the figure, there is a gap between the aluminum bar and the rigid slab that is
supported by two copper bars. At 10°C, A = 0.18 mm. The temperature in the assembly is

For each copper bar, A = 500 mm², E = 120 GPa, and acopper = 16.8 x 10° m/(m.'C).
For Aluminum bar, A = 400 mm', E = 70 GPa, and aaluminum = 23.1 x 10°m /(m.'C).
