• How Does a Wankel Rotary Engine Work?
  A Wankel rotary engine has a triangular rotor in an oval-like housing, and its three sealed pockets each complete intake, compression, power and exhaust in turn.
• How Jet Engines Work
  How jet engines turn fuel into thrust — the Brayton cycle, turbofan anatomy with compressors and turbines, bypass ratio, and what limits efficiency.
• Tribology: Friction, Lubrication, and Wear
  The science of rubbing surfaces: why friction follows simple laws, how lubricant films carry loads, and why wear is the dominant failure mode of machinery.
• The Four-Stroke Engine
  The internal combustion engine cycle of intake, compression, power, and exhaust strokes, governed by the Otto cycle.
• Stress and Strain
  The two fundamental measures of how materials respond to loads: force per unit area and fractional deformation.
