- Combined stress calculations using Mohr’s circle
- Buckling analysis for columns using Euler’s formula
- Fatigue life predictions using S-N curves
- Thermal stress calculations for temperature differentials
- Pressure vessel design according to ASME Boiler and Pressure Vessel Code
Thermodynamic Calculations
The second edition expands its coverage of thermodynamic systems with practical calculations for:
| Thermodynamic Process | Key Equations | Typical Applications |

| Adiabatic Process | PVγ = constant, Q = 0 | Internal combustion engines, gas turbines |
| Isobaric Process | W = PΔV, Q = ΔH | Boilers, condensers |
| Isochoric Process | W = 0, Q = ΔU | Constant volume combustion |
