The subject of Engineering Mechanics is that branch of applied science,which deals with the laws and principles of Mechanics,along with their applications to engineering problems.As a matter of fact,Knowledge of Engineering Mechanics is very essential for an engineer in planning,designing and construction of his various types of structure and mechanics in a most systematic and scientific manner.
BEGINNING AND DEVELOPMENT OF ENGINEERING MECHANICS
it will be interesting to know, as to how the early man had been curious to know about the different processes going on the earth, In fact,he used to content himself,by holding gods responsible for all the processes. For a long time, the man had bee trying to improve his way of working. the first step, in this direction,was the discovery of a circular wheel,which led to the use of animal driven carts.The study of ancient civilization of Babylonians,Egyptian,Greeks and Roman reveal the use of water wheels and wind mills even during the pre-historic days.
It is believed that the word 'Mechanics' was coined by a Greek philosopher Aristotle. He used this word for the problem of lever and the concept of centre of gravity.At that time,it included a few ideas,which were odd,unsystematic and based mostly on observations containing incomplete information.The first mathematical concept of this subject was developed by Archimedes.The story,for the discovery of First Law of Hydro statics,is very Popular even today in the history of the development of Engineering Mechanics.In the normal course,Hieron King of Syracuse got a golden crown made for his use.He suspected that the crown has been made with an adulterated gold. The king liked the design of the crown so much that he did not want it to be melted,in order to check its purity.It is said that the king announced a huge reward for a person,who can check melting it. the legend goes that Archimedes, a pure mathematician, one day sitting in his bath room tub realised that if a body is immersed in water,its apparent weight is reduced. He thought that the apparent loss of weight of the immersed body is equal to the weight of the liquid displaced.
It is believed that without further thought,Archimedes jumped out of the bath tub and ran naked down the street shouting 'Eureka, eureka !"i.e.I have found it, I have found it !'
The subject did not receive any concrete contribution for nearly 1600 years In 1325,jean Buridan of paris University proposed an idea that a body in motion possessed a certain impetus i.e.motion in the period 1325-1350,a group of scientist led by the Thomas Bradwardene of Oxford University did not of work on plane motion of bodies.Leonarodo Da Vinci(1452-1519),
a great engineer and painter,gave many ideas in the study of machanism, friction and motion of bodies on inclined planes.Galileo (1564-1642) established the theory of projectiles and gave a rudimentary idea of inertia.Huyghens(1629-1695) developed the analysis of motion of a pendulum.
