Answer:
1.In economics, elasticity is the measurement of the percentage change of one economic variable in response to a change in another. An elastic variable is one which responds more than proportionally to changes in other variables.
2.the maximum extent to which a solid may be stretched without permanent alteration of size or shape.
3.Definition of elastic constant. : one of the constants that express the elastic behavior of a given material — compare bulk modulus, elastic limit, poisson's ratio , shear modulus, yield point, young's modulus.
4.In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Prior to the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed.
5.Young's modulus, or the Young modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.
6.Stress is the body's reaction to any change that requires an adjustment or response. The body reacts to these changes with physical, mental, and emotional responses. Stress is a normal part of life. You can experience stress from your environment, your body, and your thoughts.
7.pressure that is put on something when it is pulled or pushed by a physical forceworry or pressure caused by having too much to deal withto make a great mental or physical effort to do something.
8.a law stating that the strain in a solid is proportional to the applied stress within the elastic limit of that solid
