Explaniton of Mechanical Engineering Concepts

1- Nanotechnology is basically a science that studies on nanoscale particles which is about 1 to 100 nanometers. These particles are very small and can be modified by nanotecnology to be used in other diciplines as well, like  materials science, chemistry, biology and physics.

2- Micro electro-mechanical systems (MEMS) is similar to nanotechnology but slightly different. It is technology of devices which work on microscobic level. Especially the particles that can move. It is generally know to work at nano-scale.

3- Biomechanics is the science of mobile body. Particularly, it examines how bones,muscles and the other componenets of the body work together to produce movement. Moreover, this science also focuses on mechanics of blood circulation and other body functions. 

4- Computational fluid dynamics is a sub branch of fluid mechanics which focuses to solve and analyze the problems that contain fluid flows. It also includes data structures and numerical anaysis to solve the problems. 

5- Composite materials are simply material made from at least two or more materials which are generally different than each other on the aspect of  chemical and physical properties. When we combine these materials, we would be able to produce a material with characteristics different from the individual components.

6- Mechatronics is an engineering field which studies on combination of different diciplines such as mechanical engineering, electronics, robotics and control engineering etc. The main goal of this field is to design process which can unify the other diciplines as well. It's like working interdiciplinary.

7- Acoustical engineering is also an enginering field which deals with sound and vibration. 

The engineers work on this field usually concer about the design, analysis and control of sound. One of the main goal  of acoustical engineering is to  reduce the unwanted noise, which is referred to as noise control.

8- Structural analysis is basically breaking-down and analyze the effect of loads on physical structures and their components.The subjects of this field can be buildings, bridges and vehicles etc. This analysis requires deep knowledge of applied mechanics, materials science and applied mathematics t be able to examine the structure. It's also know as one of the key part of engineering.

9- Friction stir welding (FSW) is an operation (or process) to joint two facing workpieces without melting the workpiece materials. As usual, when welding is done there is heat generation due to friction and it makes softened the material but in this case, it mechanically intermixes the two pieces of metal, and forges the hot and softened metal by the mechanical pressure.

10- Thermodynamics and thermo-science can be explained as the relationship between heat, energy and work. It is basically know as transfer of energy from one place to another.
