SUMMARY
The discussion centers on calculating the stress on a 25-micron fiber subjected to a 25 g elongation load. The initial calculation of stress using the formula F/A resulted in 500 MPa, which was incorrect. The correct stress value is 0.125 MPa, achieved by using the full diameter instead of the radius in the area calculation. This highlights the importance of precise measurements in stress calculations.
