Full teaching script
- Today: Statics, materials and structures. Our goal: Analyse loads and select materials.
- Take one idea at a time. Pause after each sentence; ask for repetition whenever you need it.
- Resolve forces and moments to zero for equilibrium. Stress = force/area, strain = extension/length, and their ratio in the elastic region is Young's modulus. Design to yield with a safety factor, and watch fatigue — most real failures are cyclic, not single overload.
- Together: choose one example from the explanation and show how it works. What do you notice?
- Your turn: Calculate the reactions on a simply supported beam with a central load.
- Reflect: what made sense, and what would you like explained differently?
