Mechanical engineering are included?

With the natural science and chain sprocket on scientific basis, combining with the production practice of technical experience, research and development, design, manufacture, installation, use and repair machinery theory and practical problems in the application of discipline. Modern society is mechanical manufacturing and service of five factors (people, capital, energy and materials and machines), and one in energy and material production. Modern machinery engineering has five big services:
Develop and provide energy conversion, including chain sprocket, chemical, thermal power, fluid pressure, can convert energy and natural suitable for applications of various mechanical power machinery, and will convert the energy needed to other energy transform machinery.
Develop and produce all kinds of products to provide mechanical, including agriculture, forestry, animal husbandry and fishery machine and mining machinery and various kinds of heavy machinery and light industrial machinery, etc.
Develop and provide various services such as material handling chain sprocket, mechanical, transportation, medical, mechanical ventilation, office machinery, heating and air-conditioning equipment and dust removal, purification and environmental protection equipment such as sound.
Develop and provide families and individuals living with the mechanical, such as washing chain sprocket, refrigerators, watches, cameras and sports equipment and entertainment equipment etc.
Develop and provide all kinds of mechanical weapons.
