engineering recuitment BARC Stipendiary Trainee Category I 2023 Mock Test Strength of Materials Torsion of Shaft Effect on Shaft
Pure torsion of a shaft produces:
1
longitudinal normal stress in shaft
2
only direct shear stress in the transverse section of the shaft
3
circumferential shear stress on a surface element of shaft
4
a longitudinal shear stress and a circumferential shear stress on a surface element of shaft
