Mechanical Engineering Interview Questions and Answers

Hydraulics mechanics is the study of liquids at rest and in motion, particularly under pressure. Hydraulics mechanics are used in construction equipment, airplanes, cars, manufacturing, and medicine.

Machine Design is also known as Mechanical Design which is the broadest study of Engineering Design. It is a process or mechanism by which resources or energy is converted into required mechanical forms. It also deals with the up-gradation or improvement of the existing machine. For instance, the gearbox of the car that transmits the motion and the power of the engine to the wheels of the vehicle is an example of a machine design.

Thermodynamics means that powerful heat. It works on heat movement or heat flow. The term Thermodynamics comes from the 2 Greek words "thermes" which suggests heat, and "dynamics" which suggests powerful motion or movement of energy. Thermodynamics is related to physics that features heat, work, and temperature, etc.

Power plant engineering is also known as power station engineering. it is a subdivision of power engineering. Power engineering is the engineering and technology required for the production of central station electric power. It focuses on the generation of power for industries and communities, not for household power production.

An Internal Combustion Engine is also known as an IC engine is a heat engine. In IC or Internal Combustion engine, combustion of a fuel occurs with an oxidizer inside the cylinder known as a combustion chamber that is an integral part of the working fluid flow circuit.
