Mechanics of machines describes the application of mechanics, both statics and dynamics, in solving mechanical engineering problems related to various machines, such as belt and pulley systems, gears, flywheels, gyroscopes and etc. The balancing and vibration of rotating masses and reciprocating systems are the core elements under this study.
Dynamics is a study of mechanics that concerns the action of forces in producing motions of bodies. Kinetics and kinematics of particles and rigid bodies are the principal theories. The concepts of work, momentum and energy are always integrated in the analysis to identify the behaviors and responses of a dynamical system.
Thermodynamics is a fundamental knowledge to deal with energy. The First Law of Thermodynamics and the Second Law of Thermodynamics are the very basic theoretical approaches to solve the energy related contexts. In details, the topics to learn under this subject are pure substance, heat transfer, work, closed systems, open systems, steady and transient flow processes, heat engines and reversed heat engines, reversible and irreversible processes, entropy and etc. The knowledge is applied to solve various kind of thermal engineering applications, such as internal combustion engines, gas turbines, steam power plant and refrigeration cycles.
Statics is an essential basic knowledge in mechanical and civil engineering practices. The knowledge is about to apply the resultant and equilibrium of forces to solve mechanics problems by constructing free body diagrams for particles and rigid bodies. The Newton’s Law is applied in formulating the moment and equilibrium equations to solve mechanics issues such as friction, trusses, frame and machines applications. Other related knowledge that ones should possess are the concept of distributed forces, which include centroid and centre of gravity, and the generated surface area and volume of revolution.
