- [Viscosity](https://www.hlayiso.com/grade-12/technical-sciences/notes/elasticity-viscosity-and-hydraulics/viscosity) — Viscosity When a liquid flows, its layers do not slide past one another without resistance. That resistance is called viscosity, and you see it every time oil, syrup, paint, coolant, or fuel moves…
- [Stress Strain and Hooke's Law](https://www.hlayiso.com/grade-12/technical-sciences/notes/elasticity-viscosity-and-hydraulics/stress-strain-and-hookes-law) — Stress Strain and Hooke's Law Structures and machine parts are constantly pushed, pulled, bent, or compressed. A bridge cable stretches under load, a spring extends when a force is applied, and a…
- [Pressure and Pascal's Law](https://www.hlayiso.com/grade-12/technical-sciences/notes/elasticity-viscosity-and-hydraulics/pressure-and-pascals-law) — Pressure and Pascal's Law Pressure explains why a sharp blade cuts more easily than a blunt one, why a diver feels water pressing from all sides, and why a hydraulic jack can lift a heavy vehicle…
