WHAT IS ELASTICITY AND MODULUS

Elastic modulus is a concept that defines the tenacity of a substance or material in order to find the ability of maximum elasticity. This concept of modulus and elasticity was discovered by Thomas Young, a British scientist, who suggested the need and importance of the topic. Basically, it can be stated through the understanding of the elasticity and modulus that it is defined by the proportion of strain along with the stress. The measuring unit is also known as the modulus of elasticity. It is one of the crucial subjects of physics that has a specific significance in the clearing concept of physics.

Modulus elasticity: Overview of the concept

Modulus elasticity is the fundamental concept of analysing the stretch capability of a substance. The measuring unit of the elastic modulus is pressure units. The other perspective of understanding the concept of elasticity modulus is the slope of the strain-stress curve in the graphical representation. It is noticed through the analysis of the study that a stiff body or object tends to have a greater elastic modulus. The prior formula of elastic modulus is determined by stress/strain. 

The main branch of Modulus elasticity has its other 3 sub-branches which are also as equal as the core subject of the modulus elasticity. The sub-branches are categorised into modulus of rigidity, modulus of bulk and the young’s modulus. Each of the branches of Modulus elasticity has its significance in the evaluation of the physics topic of Modulus elasticity. 

Modulus of rigidity

In science materials, the rigidity modulus is defined as the stiffness or rigidity of a body to the ratio or proportion of shear of stress to strain. In physics, the term rigidity modulus is denoted with G or S or μ. The rigidity of substance or material value is determined with the help of a torsion test. The basic or fundamental difference between the elastic modules to that of rigidity modulus is described by the application of stiffness or rigidity on a substance. In case of elasticity modules, it is mostly applicable only on the solid materials whereas in the case of rigid modules it is applicable on the liquid substance. 

The formula to find out the rigidity of modulus is expressed as S = E/ [2(v+1)], where E is described as the elastic modulus, v denotes the passions ratio within the formula. The main significance of modulus rigidity is to aid the student of the researcher of physics, who are dealing with these subjects and benefit from it. 

The interrelationship between Modulus of elasticity and Modulus of rigidity

Elasticity modulus and rigidity models both are a part of British cities Young Thomas’s research work. Through the in-depth analysis of the young’s modulus, it can be understood that the study focuses on the elasticity and rigidity of a substance. Upon learning the concept of the three factors of young’s modulus, they are altogether termed as the elastic constants. The interrelation between modulus of rigidity and that of elasticity is the conditioning or taste of substance used in the functioning of the process. The interconnection between these two modules can be started with the help of a formula: E= 2G (μ +1). 

Importance of Modulus elasticity in real life 

There is great importance on the case study of the elastic modulus in real life. The day-to-day implementation of the concept comes into play the most in the case of the civil engineer. Civil engineers deal with the daily managing, organisation and balancing of construction-oriented projects. Thus, in this case, the elastic modulus comes in very handy and aids them in better management of the work in construction. As elastic modulus states the strength of a substance, it allows the civil engineers to analyse and perform acts for the projects. 

Conclusion 

Elastic modulus is one of the vital topics for students studying physics. In the study, it can be seen that the study discusses the core concept of the modulus elastic and its significance. On in-depth analysis of the topic of elastic modulus, it can be seen that it deals with the understanding of the ratio of stress with strain. The study furthermore pivots on the core concept of modulus rigidity. The importance of the elasticity and modulus lies in the fact of evaluating the property of the material on its stiffness. The concept of stress and strain in elasticity modulus is primarily concentrated on solid materials and their properties.
