What is the Full Form of MOS in Mechanical Engineering?


What does MOS stand for in Mechanics? - Full form of MOS

Full Form of MOS in Mechanical Engineering - Full Form, Meaning, and Definition

The full form of MOS in Mechanical Engineering is: MECHANICS OF SOLIDS

What is the meaning of MOS in mechanical engineering?

Mechanics of solids (also known as solid mechanics) is one of the fundamental applied engineering sciences and is the study of the behavior of solid materials.

MOS studies the motion and deformation of solids when they come under the action of forces and is a very vast subject. 

These forces may include temperature changes, tension forces, spring forces, etc.   

What are the Best ways to learn the mechanics of solids? (Best books to refer to for MOS)

You can learn the mechanics of solids by reading journals, articles, books, etc., and by making sure that all your concepts are clear.

Following are the books you can refer to for a clear understanding and gain more insights on the subjects:
  • A Textbook of Strength of Materials (R K Bansal)
  • Strength of Materials (S. Ramamrutham)
  • Mechanics of Materials by Gere and Goodno of Cengage Publications
  • Introduction to Mechanics of Solids by Crandall 
  • Strength of materials by Gere and TiMOShenko

What is computational solid mechanics? 

Computational solid mechanics deals with the study of principles of mechanics using computational science or performing analysis and simulation using software on the computer.  

Is the mechanics of solids and the strength of the material the same? 

MOS and Strength of Materials are not the same with Strength of Materials being a part/constituent of Mechanics of Solids. Strength of Material helps the engineer in identifying the strength of a material by measuring its stress and strains upon subjecting forces on the solid.  

What are the aspects of MOS?

What is the Full Form of MOS in Mechanical Engineering

  • It examines if any structure can go back to a given equilibrium after partially being failed.
  • Materials that emerged from thermodynamic principles are analyzed by it.
  • It makes use of solid mechanics to biological materials.
  • MOS also deals with those mechanical systems which are highly delicate in their early stages.
  • It applies solid mechanics to geological things like ice, rock.
  • The examination of vibration and waves from vibrating particles is very vital in mechanical engineering.
  • It deals with fractures in solid materials.
  • MOS also manages variational formulation of Mathematics arising from different branches of solid material.

How does a solid respond to applied stress?

  1. Elasticity: When employed stress is released the material goes back to its normal state.
  2. Plasticity: When the applied stress is higher than the required stress then the material behaves plastically and it never goes back to its undeformed stage. In this case, the deformation is permanent.
  3. Viscoelasticity: These are some materials whose response depends on time. These things act like elastic but also have humidity. Hence when stress is given and removed the material becomes like a hysteresis loop.
  4. Viscoplasticity: It is a combined theory of viscoelasticity and plasticity. It is applied to materials like gel, clay, etc.
  5. Thermoelasticity: It is about the elastic solids that are neither adiabatic nor isothermal.

What is load in solid mechanics?

The forces which are given externally on the materials are called ‘load’. Following are the reasons for the applied forces.

Because of the environment where the components work.
  • Due to service conditions.
  • Due to the pressure of the liquid.
  • Because of gravity or inertia.
  • Due to the contact with other materials.
