The formula to calculate stress is:
\[ \sigma = \frac{F}{A} \]
Where:
Stress is a measure of pressure that the particles and atoms within a material exert on each other when a force is applied. This is not the same as pure pressure. Stress is also related to strain and Young’s modulus, a ratio of stress to strain in an object under a certain force denoted by this equation: (E = \frac{\sigma}{\epsilon}).
Stress and strain are linearly proportional when under elastic behavior. When an object breaks or starts to yield, this relationship no longer holds.
Let's assume the following values:
Using the formula:
\[ \sigma = \frac{1000}{0.5} = 2000 \]
The stress is 2000 N/m².
