Mechanical Engineering

Mechanical engineering is one of the oldest branches of engineering that incorporates principles of physics and materials science in designing, analyzing, manufacturing, and maintenance of mechanical systems. It lies at the very core of building up the technological environment surrounding us. The role of a mechanical engineer in a number of industries, such as automotive, aerospace, electronic, energy, manufacturing, and many others, is quite fundamental.

Key concept of Mechanical Engineering:

There are concepts used in mechanical engineering with the first being thermodynamics.

Thermodynamics is the study of the internal energy of a system, heat added and work done. It describes how energy is transformed from one form to another and the change it does to matter.

Laws of thermodynamics:

There are mainly three laws that regulate it.

First law: Energy can not be created or destroyed only transformed. The principle is essential since it lays a basis for understanding how energy can be conserved in mechanical systems.

Second law of thermodynamics: Heat cannot spontaneously flow from a colder body to a hotter body. This law introduces the property called entropy, S, in some sense a measure of disorder of a system.

Third law: As the temperature of a system approaches absolute zero, its entropy approaches a constant minimum.

The next is the fluid mechanics. Fluid mechanics is concerned with the study of fluids, both liquids and gases, along with the principles of their actions under different circumstances. It becomes absolutely essential during the design of systems transporting fluids, such as pipelines, pumps, and HVAC systems.

Lastly, kinematics and kinetics. Kinematic is the description of motion without considering forces involved that may cause such motion. It deals with trajectory analysis of the bodies in motion and their velocities and accelerations. Kinetics: Studies the relation between the motion of bodies and the forces acting upon them. It helps engineers design systems that can withstand and respond to such forces.

Areas of specialization:

By studying mechanical engineering, one could specialize in the following areas:
