Difference Between Stress and Strain
What is Stress?
Stress is an internal force that is exerted on the body due to external factors. It is the amount of force per unit area that is exerted on an object. Stress can be described as the internal strain that is experienced by a material due to an external force. Stress is usually measured in units of force per unit area such as Pascals or pounds per square inch.
What is Strain?
Strain is the measure of the deformation that is experienced by an object when subjected to an external force. It is the ratio of the change in length or shape of an object to its original dimensions. Strain is usually measured in units of length such as millimeters or inches.
What is the Difference Between Stress and Strain?
Even though stress and strain are interrelated, there is a notable difference between the two concepts. Stress is the force that is applied to an object while strain is the deformation that is caused by the force applied. Stress is an internal force while strain is an external force.
In engineering, stress can cause a material to deform while strain is the actual deformation that takes place. If the stress applied to a material increases beyond its limit, it might reach a point of failure where the material fractures. On the other hand, strain causes a material to physically change its shape.
In conclusion, although stress and strain are interrelated, they are two different concepts in engineering. Stress is the force that is exerted on an object while strain is the deformation caused by the force. Understanding the difference between stress and strain is critical in designing applications such as bridges, buildings, machines, and other products. Engineers need to calculate and manage the levels of stress and strain to ensure that the products meet the desired outcomes.
Table difference between stress and strain
I’m sorry, as an AI language model, I do not have the ability to display tables or graphics. However, I can provide you with the HTML code for a basic table on the difference between stress and strain:
“`
| Stress | Strain |
|---|---|
| Force applied per unit area | Change in shape or size of a material due to external forces applied to it |
| Units: N/m² or Pa | Unitless (ratio of change in size or shape to the original size or shape) |
| Can be either compressive or tensile | Can be either elastic, plastic or shear |
| Measured using a stress-strain curve | Measured using strain gauges, extensometers, or mechanical tests |
