Hooke’s Law
Hooke’s Law states that within elastic limit of a material, the strain resulted in the material is directly proportional to the stress applied. In this limit, the graph between stress and strain is linear in nature and from the yield point the nature of the graph changes. The mathematical expression for Hooke’s Law is given as
σ = Yε
where,
- σ is Stress
- Y is Young’s Modulus
- ε is Strain
The Graph for Hooke’s Law is shown using the Stress-Strain Curve in the image below:

What is Stress?
Stress in physics is defined as the force exerted on the unit area of a substance. Stress affects the body as strain in which the shape of the body changes if the stress is applied and sometimes it gets permanently deformed. On the basis of the direction of force applied to the body, we can categorize stress into three categories that include,
- Longitudinal Stress
- Bulk Stress
- Shearing Stress
Apart from these three, there are also other types of stress that we will learn in this article. In this article, we will also learn about what is stress, the types of stress, the Formula for stress, the unit of stress, and others in detail.
