What is stress and strain? Describe the graph of stress-strain. How braking system works

Question

Accepted Answer

Stress is the force applied to a material, while strain is the resulting deformation. The stress-strain graph shows the relationship between stress and strain for a material.

Stress is the force applied per unit area on a material, measured in units like Pascals or psi.
Strain is the resulting deformation or change in shape of the material, typically expressed as a percentage.
The stress-strain graph typically shows a linear elastic region where stress and strain are directly proportional, followed by a plastic region where the material deforms permanently.
The ultimate tensile strength is the maximum stress a material can withstand before breaking.
The braking system in a vehicle works by converting kinetic energy into heat through friction between the brake pads and the rotor.
