The pin-connected structure shown in the figure consists of two cold-rolled steel (E = 30,000 ksi) bars (1) and a bronze (E = 15,000 ksi) bar (2) that are connected at pin D. All three bars have cross-sectional areas of 0.375 in². A load of P = 11 kips is applied to the structure at pin D. Using a = 3 ft and b = 5 ft, calculate the downward displacement of pin D.

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.
