SUMMARY
The discussion focuses on calculating the smallest cross-sectional area of a rod-end under stress in structural mechanics. A force of 50 kN is applied at pin C on rod BC, with the stress calculated using the formula 4P/πd² for the circular cross-section and P/wt for the rectangular end. The discussion highlights that the effective width is reduced due to material being cut out for the pin, leading to an increased stress calculation of P/(w-d)t at that section. This emphasizes the importance of considering geometric changes in stress analysis.
