Describe elastic hysteresis. Mention its few applications.

Elastic hysteresis refers to the phenomenon where a material experiences a difference in its stress-strain behavior during loading and unloading cycles. When a material is stretched and then released the energy absorbed during deformation is not entirely recovered resulting in ...

The thickness if metallic ropes used in cranes to lift heavy loads is decided from the knowledge of the elastic limit of the material and the factor of safety.

The elastic limit is the maximum stress or force that a material can withstand without undergoing permanent deformation. Beyond this limit the material will not return to its original shape when the applied force is removed. Understanding the elastic limit ...
