What is stress, poisons ratio, endurance limit?

Question

Accepted Answer

Stress is the force per unit area, Poisson's ratio is the ratio of lateral to axial strain, and endurance limit is the maximum stress a material can withstand without breaking after a certain number of cycles.

Stress is the measure of the internal forces acting within a material, which can cause deformation or failure.
Poisson's ratio is a measure of a material's ability to deform in response to an applied force, and is defined as the ratio of lateral strain to axial strain.
Endurance limit is the maximum stress a material can withstand without breaking after a certain number of cycles of loading and unloading.
For example, a metal bridge may experience stress due to the weight of traffic passing over it, and its endurance limit would be the maximum stress it can withstand without developing cracks or other damage over time.
Poisson's ratio is important in determining how a material will behave under different types of stress, such as compression or tension.
The endurance limit of a material can be affected by factors such as temperature, corrosion, and the number of cycles of loading and unloading it experiences.
