FACTORS AFFECTING ELASTICITY : a. Effect of temperature : In general as the temperature increases the elastic property of a material decreases. b. Effect of impurities : Addition of impurity to metal may increase or decrease the elasticity. If the impurity has more...

Hooke’s Law Hooke’s law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance. That is: where is a constant factor characteristic of the spring, its stiffness. where is...
