What is Hooke’s Law of Elasticity in Physics

Hooke’s Law of Elasticity in Physics

 

Introduction:

 

An English Physicist and Chemist Robert Hook discovered this law in 1678.

 

Statement

“Strain produced is proportional to the stress exerted within the elastic limit.

 

Elastic Limit: The point at which a material becomes plastic is called elastic limit on yield point.

 

Yield Point: The yield point is the point at which the material begins to flow. It is also the point between elastic region and plastic region.

 

Elastic Region: When the material obey’s Hook’s Law, it is said to be in Elastic Region.

 

Plastic Region: When stress is applied beyond the elastic limit, the graph is no longer a straight line. In this case stress produces a permanent change in the material. The material is said to be in its Plastic Region.

 

Breaking Point: The material breaks at a certain point called the Breaking Point of the material.

 

Note: This educational technology has a number of significant advantages, otherwise this rule would not be contained in the new Federal Law “On Education”. Distance learning by purpose, content and result is not inferior to full-time education. Moreover, constant contact with the teacher and participation of the learner in active forms of the organization of the educational process (seminars, conferences, training discussions, master classes) gives this learning technology clear advantages over the correspondence form; Distance education is capable, to a greater extent than the traditional full-time or correspondence, to provide an opportunity for each student to flexibly build an individual educational trajectory; plus it should also be attributed to the fact that e-learning is technological, it creates a unique information environment, without which modern education is impossible, but which, it must be admitted, is not always fully realized in full-time education.
