SUMMARY
The discussion focuses on calculating the total extension and tensile stress in a machined steel bar subjected to an axial tensile load of 84 kN. The bar, measuring 375mm in length, features three distinct diameters: 75mm for the first 175mm, 45mm for the next 100mm, and 37mm for the final 100mm. The Young's modulus (E) is given as 200 GN/m². The solution approach involves treating the bar as three separate segments, each with its own spring constant, to determine the total extension and stress in each section.
