Introducing comprehensive contents of mechanical engineering

In modern life, almost everything near our daily life is related to the product we bought

for our convenience. For example, smart phone, TV, iPod etc. are things which

occupy our life mostly.  Then, it might be a natural question for us to think how does

this products are made and developed. Engineering and technology is the answer for

this simple question.

Today, I'm going to show you a brief and essential contents of Mechanical

engineering.

Firstly, I'll show you a history  and various filed of of mechanical engineering.  

Mechanical engineering emerged as a field during the industrial revolution in Europe

in the 18th century; however, its development can be traced back several thousand ry

years around the world. Mechanical engineering science emerged in the 19th century

as a result of developments in the field of physics. The field has continually evolved

to incorporate advancements in technology, and mechanical engineers today are

pursuing developments in such fields as composites, mechatronics, and

nanotechnology.

As you can recognize easily, two big point of view exist.

Answer is that macro, and micro engineering science and technology is different from

each other. Because, the physics which explain the movement of both part is quite

different.

To understand the mechanical engineering more deeply, you need to know the

big 4 subjects of mechanical engineering which are easy to know by sense.

There are dynamics, mechanics of materials(statics), thermodynamics, and fluid

mechanics. These subjects show that mechanical engineering is basically based on

classical newton dynamics. Most of you might have heard about F=ma.

I think this simple equation is used in 4 main subject almost every cases.

 Also, this study is really adaptive to other area, so in almost every situation where we

need to make a product, mechanical engineering and technology is used to enhance

the efficiency of the whole system to economize and optimize the design.

This is the most important reason that this study is attractive and essential for

our living.
