SUMMARY
The discussion focuses on calculating stress and strain in a spring experiment using the formulas σ=F/A (stress equals force divided by area) and ε=∆x/l (strain equals change in length divided by original length). Participants express confusion regarding how to determine the cross-sectional area of the spring for accurate calculations. It is noted that plotting force against strain will yield a stress/strain graph, although the units for stress will be in arbitrary units of force per spring area.
