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 …

Chapter 1.5, Problem 52P

The bar has a cross-sectional area of 400(10⁻⁶) m². If it is subjected to a triangular axial distributed loading along its length which is 0 at x = 0 and 9 kN/m at x = 1.5 m, and to two concentrated loads as shown, determine the average normal stress in the bar as a function of x for 0 ≤ x < 0.6 m.
