Elaboration
- metallurgy:
- austenite and martensite crystalline lattice structures/hardening metals
- tempering colour in ferrous and non-ferrous metals/alloys
- stress–strain graphical analysis (yield point, ultimate strength, breaking point)
- welding:
- carburizing, neutralizing, and oxidizing flames in gas welding
- inert gas in MIG and TIG welding (e.g., argon, CO2)
- electrode classification in arc welding
- carpentry, construction, and joinery:
- structures and codes
- concrete admixtures (e.g., air entrained, water reducers, retarders, accelerators)
- glue technology (e.g., epoxies, polyurethanes, cyanoacrylates, polyvinyl acetate [PVA], construction adhesives, contact cements, urea-resorcinol resins), monomers, polymers
- tangential, radial, and transverse wood grains
- power mechanics:
- hydraulic systems
- pressure
- quantitative analysis (e.g., horsepower and torque area under the curve, top dead center [TDC], static compression)
- plumbing and gas fitting:
- hydronic systems (thermodynamics: convection, conduction, and radiation)
- gas-fired systems (specific heat, specific gravity)
- pressure systems (Boyle’s law, Charles’ law, combined gas law, Bernoulli’s principle)
- electrical and computing:
- circuits and electronics (Ohm’s law, Kirchhoff’s law)
- integrated circuits
- solar photovoltaic (PV) modules
- forensics and criminology
- hairstyling and aesthetics:
- hygiene, sanitation, and disinfection practices
- chemical waving and relaxing
- hair colouring
- petroleum and industrial:
- fractional distillation
- dilution
