Mechanical engineering is regarded as one of the disciplines of core engineering and deals with the entire gamut of mechanical systems. Analysis, design, manufacture as well as maintenance of these systems come under the purvey of mechanical engineering too. Use of heat and power are the characteristics of this discipline also regarded as one of the most ancient forms of engineering that has remained relevant for centuries despite the ascendant and progress of new age engineering disciplines. However, mechanical engineering has advanced quite a bit from the older days with the inclusion of nanotechnology, mechatronics, and composites today. While mechanical engineering has given rise to several branches that are regarded as separate disciplines at present, the basic form of mechanical engineering continues to make use of the following
