What are the mechanical categories?
There are many kinds of machinery, can be divided into several different aspects of various categories, such as: according to the function can be divided into power machinery, material handling machinery, grinding machinery etc.; according to the service industry can be divided into agricultural machinery, mining machinery, textile machinery and so on; according to the working principle can be divided into mechanical and thermal fluid machinery, bionic machinery etc..In addition, machinery in its research, development, design, manufacture, use and so on, there are several stages of work in different nature. According to these different stages, mechanical engineering can be divided into several branch systems, such as mechanical research, mechanical design, mechanical manufacture, mechanical application and maintenance.

These various branches are divided into one another and overlap each other, so that mechanical engineering may be divided into hundreds of branches. For example, according to the dynamic mechanical function, and according to the working principle of thermal mechanical, fluid machinery, turbine machinery, reciprocating machinery, steam power machinery, nuclear power plant, internal combustion engines, gas turbines, and by industry center of power plant equipment, industrial power equipment, railway locomotives, marine engineering, automotive engineering there are complex and overlapping relationship. Marine steam turbines are power machines, as well as thermal machinery, fluid machinery and turbine machinery. They belong to marine power plants, steam power plants, nuclear power plants, and so on.Analyzing this complex relation and studying the most rational branch system of mechanical engineering has certain knowledge meaning, but it is not of great practical value.
