Material Properties Simulation
This simulation demonstrates two key concepts in material science:
- Young's Modulus: Comparing the stiffness of rubber vs. steel (steel has higher Young's modulus)
- Shear Modulus: Showing how a coil's stretching is determined by its shear modulus
Young's Modulus Comparison
Observation: For the same applied force, rubber stretches more than steel. This shows steel has a higher Young's modulus (stiffer material).
Young's modulus (E) = Stress / Strain. Since rubber has more strain for the same stress, its Young's modulus is lower.
Shear Modulus in Coil Stretching
Observation: When stretching a coil, the shape changes (shear deformation) rather than just length changing. This is governed by the shear modulus (G).
Shear modulus describes a material's response to shear stress (shape change without volume change).
