To calculate the elastic modulus (\(E\)):
\[ E = \frac{Se}{Sa} \]
Where:
Elasticity is a fundamental concept in physics that describes the property of materials to deform under the application of external forces and return to their original shape when the forces are removed. It measures how much a material can stretch or compress when subjected to stress.
When a force is applied to an object, it generates stress, causing the object to change its shape. Elastic materials can absorb this stress and store potential energy. As a result, they can undergo temporary deformation while maintaining their original structure. Once the external force is removed, the stored energy is released, causing the material to return to its initial state.
Let's assume the following values:
Using the formula:
\[ E = \frac{500}{0.02} = 25000 \]
The elastic modulus is 25000 N/m².
Let's assume the following values:
Using the formula:
\[ E = \frac{300}{0.015} = 20000 \]
The elastic modulus is 20000 N/m².
