SUMMARY
The discussion focuses on determining compressive and tensile stresses in beams using the equations σ = My/I and σ = -My/I. It is established that compression is always represented as a negative value, while tension is positive. Participants clarify that when calculating maximum stress, the positive form of the equation should be used, and the negative sign is added only at the end for compressive stress calculations. This approach helps avoid confusion in stress analysis.
