Stress, Strain & Hooke's Law
Push or pull on a rigid body and, strictly, no body is perfectly rigid — it changes shape or size, however slightly. When an external force acts on a …
Start this topic → 2Moduli of Elasticity
Hooke's law tells us that stress divided by strain is a constant — the modulus of elasticity . Because a solid can be deformed in three distinct ways …
