SUMMARY
The discussion centers on the application of the plane stress transformation equations to determine the principal stresses SigmaX' and SigmaY' at an angle of -23.7 degrees. Substituting this angle into the equations yields SigmaX' as -46.42 MPa and SigmaY' as 116.4 MPa. The key question raised is how to definitively associate the angle -23.7 with SigmaX' instead of SigmaY'. Understanding the relationship between the rotation angle θ and the transformed axes is crucial for clarity in this context.
