A gas is stored in a cylindrical tank of inner radius 7 m and wall thickness 50 mm. The gauge pressure of the gas is 2 MPa. The maximum shear stress (in MPa) in the wall is
-
- 35
- 70
- 140
- 280
- 35
Correct Option: C
σc = | = | = 280 MPa | ||
2t | 2 × 0.05 |
σl = | = | = 140 MPa | ||
4t | 4 × 0.05 |
Maximum shear stress,
τmax = | = | = 70 MPa | ||
2 | 2 |
Note: This stress τmax is the maximum in-plane shear stress.
Absolute τmax will be | = 140 Mpa | |
