Thermodynamics: Thermodynamics is the study of the relationship between heat, energy, and work. In mechanical engineering, thermodynamics is used to design and analyse engines, refrigeration systems, and other mechanical systems that involve heat transfer. It encompasses several subfields, including classical thermodynamics, statistical thermodynamics, and chemical thermodynamics.

As mechanical engineering begins to merge with other disciplines, as seen in mechatronics, multidisciplinary design optimization (MDO) is being used with other CAE programs to automate and improve the iterative design process. MDO tools wrap around existing CAE processes, allowing product evaluation to continue even after the analyst goes home for the day. They also use sophisticated optimization algorithms to more intelligently explore possible designs, often finding better, innovative solutions to difficult multidisciplinary design problems. Mechanical engineers research, design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.

Energy: In the energy industry, mechanical engineering is used to design and develop energy systems, such as power plants and r enewable energy systems. Mechanical engineers in this field work on everything from thermodynamics and fluid dynamics to materials science and control systems. where F is the force, d is the displacement, and the angle (theta) is defined as the angle between the force and the displacement vector. Perhaps the most difficult aspect of the above equation is the angle “theta.” Theta is defined as the angle between the force and the displacement.

Note: fluid mechanics can be further split into fluid statics and fluid dynamics, and is itself a subdiscipline of continuum mechanics. The application of fluid mechanics in engineering is called hydraulics and pneumatics. Newton developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound. In mathematics, Newton shares the credit with Leibniz for the development of differential and integral calculus.Industrial engineers require mathematics to design, develop, test and evaluate integrated systems for managing industrial production processes, including human work factors, quality control, inventory control, logistics and material flow, cost analysis and production coordination. Mechanical engineers play a key role in solving key global challenges, from developing sustainable energy sources to improving the lifespan of battery technology. Xia, Ting (3 February 2003).

For the more general case of a variable force F(x) which is a function of x, the work is still the area under the force curve, and the work expression becomes an integral.
