Shear force and bending moment diagrams, neutral axis and bending stress (σ = My/I)

What this note covers

1. Shear force: what it is and how to draw it
2. Bending moment diagrams from the SFD
3. Neutral axis, outer fibres and bending stress
4. Why section shape matters: I-beams and second moment of area
5. Uniformly distributed loads: describe, do not calculate
6. Bending in context: the exam question pattern
7. Practice set with answers
