• 3D Printing: Additive Manufacturing
  How 3D printing builds objects layer by layer — the main technologies (FDM, SLA, SLS, metal powder-bed), where they win against machining, and where they still lose.
• Crowd Dynamics and Crowd Safety
  How crowds physically behave — density, flow, and the crowd-crush mechanism — and why crowd disasters are preventable engineering failures, not stampedes of panic.
• 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.
• Stress and Strain
  The two fundamental measures of how materials respond to loads: force per unit area and fractional deformation.
• Structural Loads and Beam Bending
  How engineers classify loads, and how bending moment and deflection are computed for beams — the backbone of structural design.
