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

1. Steel rod 2.5m long is secured between tow walls. If the load on the rod is zero
at 20°C, compute the stress when temperature drops to (-20°C). The cross-sectional
area of the rod is 1200 mm a=11.7µ m/(m.°C) and E=200 GPa. Solve assuming (a)
that the wall is rigid and (b) that the wall spring together a total distance of
0.500mm as the temperature drops.
