Ans.

Stress is the force applied to a material, strain is the resulting deformation, and stress-strain curve shows the relationship between them.

Stress is the force per unit area applied to a material.
Strain is the measure of deformation or change in shape of a material.
Stress-strain curve illustrates the relationship between stress and strain for a given material.
It helps in understanding the material's mechanical properties, such as elasticity, yield strength, and ultimate stren...read more

Ans.

Linear analysis assumes linear relationships between inputs and outputs, while non-linear analysis considers non-linear relationships.

Linear analysis assumes small changes in inputs result in proportional changes in outputs.
Non-linear analysis considers large changes in inputs may result in disproportional changes in outputs.
Examples of non-linear behavior include material yielding, large deformations, and contact interactions.

Ans.

Degree of freedom refers to the number of independent variables or parameters that can vary in a system.

Degree of freedom determines the number of ways a system can move or change.
In mechanics, it represents the number of independent coordinates needed to describe the position of a body.
In statistics, it refers to the number of values in a calculation that are free to vary.
For example, a particle in three-dimensional space has three degrees of freedom, corresponding to its x,...read more
