Explanation:
Hoops Stress:
- The hoop stress in a thick cylindrical shell is the stress acting circumferentially along the thickness of the shell.
- This stress is tensile in nature as it tends to pull the material apart in the circumferential direction.
Radial Stress:
- The radial stress in a thick cylindrical shell is the stress acting radially across the thickness of the shell.
- This stress is compressive in nature as it tends to push the material inwards towards the center of the cylinder.
Longitudinal Stress:
- The longitudinal stress in a thick cylindrical shell is the stress acting along the length of the shell.
- This stress is tensile in nature as it tends to pull the material apart in the longitudinal direction.
Therefore, the correct answer is option 'D', where the hoop stress is tensile, radial stress is compressive, and longitudinal stress is tensile.
