The stepped rod shown in the figure is made of Al 2014-T6 aluminum alloy. At temperature TI = 20°C, there is a gap of 0.2 mm between point A and the rigid wall. If the temperature is increased to Tr-50°C and an axial compressive force of P= 20 kN is applied at point B, determine the support reactions at points A and C. 80 mm B A 20 kN 120 mm 400 mm 600 mm 0,2 mm

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.
