Thick Cylinder Subjected to Fluid Pressure:

When a thick cylinder is subjected to fluid pressure, different stresses are developed in the cylinder. The correct statements regarding the stresses developed in the thick cylinder subjected to fluid pressure are given below:

1. Radial stress is compressive
2. Hoop stress is tensile
3. Hoop stress is compressive
4. Longitudinal stress is tensile and it varies along the length
5. Longitudinal stress is tensile and remains constant along the length of the cylinder

Correct Answer: Option C (Only 1, 2 and 5)

Explanation:

1. Radial stress is compressive:

The radial stress is defined as the stress developed in the radial direction. In the case of a thick cylinder subjected to fluid pressure, the radial stress is compressive. This means that the material is being compressed in the radial direction.

2. Hoop stress is tensile:

The hoop stress is defined as the stress developed circumferentially around the cylinder. In the case of a thick cylinder subjected to fluid pressure, the hoop stress is tensile. This means that the material is being stretched circumferentially around the cylinder.

3. Hoop stress is compressive:

This statement is incorrect. The hoop stress is always tensile in the case of a thick cylinder subjected to fluid pressure.

4. Longitudinal stress is tensile and it varies along the length:

The longitudinal stress is defined as the stress developed along the length of the cylinder. In the case of a thick cylinder subjected to fluid pressure, the longitudinal stress is tensile and varies along the length of the cylinder. The stress is maximum at the ends and minimum at the middle.

5. Longitudinal stress is tensile and remains constant along the length of the cylinder:

This statement is incorrect. The longitudinal stress varies along the length of the cylinder and is maximum at the ends and minimum at the middle.

Therefore, the correct statements are 1, 2 and 5.
