SUMMARY
The discussion centers on the presence of normal stress in a torsional member, specifically a circular rod with a rectangular hole subjected to torsion. It is established that while torsional shear stress is present along the longitudinal axis of the rod, normal stresses arise when examining elements inclined to that axis, as demonstrated through Mohr's circle calculations. This indicates that normal (tensile and compressive) stresses can exist in addition to shear stress when torsion is applied.
