Structures Or Why Don't Things Fall Down (Reading)
Chapter 2 Why Structures carry loads?
1) Action and reaction are equal and opposite.
2) The science of elasticity is about the interactions between forces and deflections in materials and structures.
3) Elastic: Loading and unloading structures don't cause any permament change of shape.
4) Plastic: Do not recovery to its original shape
Chapter 3 The invention of stress and strain
1) stress = load / cross-sectional area
stress tells us how much force could pull apart the atoms
2) strain = increase of length / original length
strain tells us how far could pull apart the atoms
3) Young's modulus = strain / stress
Chapter 4 Designing for safety
1) stress at the tip is raised to s(1 + 2 √(L/r))
Chapter 5 Strain energy and modern fracture mechanics
“The scientific kind of energy”

“of r, then the stress”
