What is Theory of Machine?




Theory of machine is a branch of engineering science that deals with the study of motion, forces, and energy transfer in machines and mechanisms. It involves the analysis and design of mechanical systems that perform specific tasks or functions, such as engines, pumps, turbines, robots, etc.


Definition and scope of the subject




According to Thomas Bevan, theory of machine can be defined as "the science which treats of those natural phenomena which are involved in the action or operation of machines". He further states that "the scope of this science is very wide, for it includes not only the study of those natural phenomena which are directly concerned with the production or transmission of motion or power, but also those which affect the efficiency or performance of machines".


Applications and importance of theory of machine




Theory of machine has many applications and importance in various fields of engineering and technology. Some examples are:



  • It helps to understand the working principles and characteristics of different types of machines and mechanisms.



  • It helps to design and optimize new machines and mechanisms that meet certain specifications or requirements.



  • It helps to analyze and improve the performance, efficiency, reliability, safety, and durability of existing machines and mechanisms.



  • It helps to solve various problems related to motion, forces, energy, vibrations, friction, lubrication, etc. in machines and mechanisms.
