In a thin-walled cylinder under internal pressure, two principal stresses act on the wall: hoop stress and longitudinal stress.
Given:
- Hoop stress, σh = 40 MPa
- Longitudinal stress, σl = 20 MPa
- Radial stress = 0 MPa (negligible in thin cylinders)
Formula for Maximum Absolute Shear Stress:
\(\tau_{\text{max}} = \frac{1}{2}(σ_{\text{max}} - σ_{\text{min}})\)
Calculation:
\(\tau_{\text{max}} = \frac{1}{2}(40 - 0) = 20~\text{MPa}\)
