A thin walled cylindrical pressure vessel having a radius of 0.5 m and wall thickness of 25 mm is subjected to an internal pressure of 700 kPa. The hoop stress developed is
-
- 14 MPa
- 1.4 MPa
- 0.14 MPa
- 0.014 MPa
Correct Option: A
| Hoop stress: σ = | (circular sphere) | 2t |
| σ = | (Cylindrical section) | 2t |
| = | = 14 × 106 = 4 MPa | 25 × 10-3 |
