Three parallel vertical rods of equal length (L-2m) support a rigid beam AB to which a force (P-40kN) is applied. The middle rods is shorter than its design length by (A=0.2 mm). During operation the temperature of the assembly may rise by (20°C). Find the stresses in each rod. 1.5 m 1 m Copper A=200mm Steel Steel A=100mm2 A=300mm E=200GPA a=13×106 E=100GPA E=200GPA a=17x10 a=13×10C A 0.2mm C B 0.25m P=40KN

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.
