Study Notes
Physics Course Topics
- Elasticity and fluid mechanics are typically covered in a dedicated chapter within the physics curriculum, often found in intermediate mechanics courses.
Young's Modulus
- Young's modulus measures the tensile or compressive stiffness of a material.
- It describes how much a material will elongate or shorten under axial load, defined as the ratio of tensile stress to tensile strain.
Shear Modulus
- Shear modulus quantifies a material's response to shear stress.
- It is the ratio of shear stress to shear strain, indicating how much a material deforms in response to forces acting parallel to its surface.
Bulk Modulus
- Bulk modulus reflects a material's response to uniform pressure applied in all directions.
- It is the ratio of volumetric stress to the change in volume, indicating resistance to compression.
Elastic Modulus Formula
- The general formula for elastic modulus (E) combines Young's modulus (Y), shear modulus (S), and bulk modulus (K) for different deformation types.
- For Young's modulus: ( E = \frac{\text{Stress}}{\text{Strain}} )
- Other moduli have similar formulations relating stress and their respective strain types.
