What to Focus On
- Elasticity: Regains original shape and size after force removal.
- Plasticity: Retains deformed shape permanently.
- No material is perfectly elastic or plastic.
- Matter is made of molecules with inter-molecular forces.
- At equilibrium separation (R₀), net force is zero.
- R > R₀: Attractive force; R < R₀: Repulsive force.
- Deformation changes inter-atomic distances.
- Restoring forces develop due to inter-atomic forces.
- Atoms return to equilibrium positions in elastic materials.
Common Mistakes to Avoid
Rubber is more elastic than steel because it stretches more.
Stress and pressure are the same because both are force per unit area.
Strain has units because it's a measurement of extension.
Memory Tips
Definition of Elasticity
Stress = Force / Area
Three Types of Stress: Longitudinal, Normal, Shearing
Longitudinal Stress – Tensile and Compressive
