Answer:
The stress-strain curve provides design engineers with a long list of important parameters needed for application design. A stress-strain graph gives us many mechanical properties such as strength, toughness, elasticity, yield point, strain energy, resilience, and elongation during load. It also helps in fabrication.

Physical significance of stress and strain are as follows:
The stress analysis of various materials is used to determine the yield point, ultimate tensile strength, fracture strength, etc. Thus, various materials are characterized with the strength values so as to use it as a parameter while designing various structures. So, it aids with the material selection for various applications like in construction field or in machine design, etc.
The amount of stress occurred in the body for a particular amount of strain helps determine whether the body is rigid and stiff or it is highly ductile. This determination of properties for various materials is quite useful for various purposes.
The stress and strain signifies the lifetime of a component. It also signifies its endurance limit, the number of stress cycles it can tolerate. This helps in keeping a limit on the use of that particular component as prolonged use after the specified limit of time might result in failure.
The stress and strain helps in keeping a limit on the load that can be tolerated by the component, thereby helping in selection of a particular material which can handle the required adversities and improving the performance of the assembly as a whole.
