The cross section of the rod in the picture is a circle and the elastic modulus of the material is 200 GPa (material S235JRG2). The rod is pulled with a force of F = 5250 N. Determine the minimum value of the rod diameter d when the rod length is L = 5250 mm and a length change of ΔL = 4.0 mm is allowed for the rod. Also determine the safety with respect to the rod. Use units in calculations [N, mm] Enter the answer to one decimal place. Do not round the invoices in the intermediate stages, but only the final answer!

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.
