Introduction (Engineering Mechanics)

In this modern age, the word ‘science’ has got different meanings for different people. An ordinary man takes it as ‘something’ beyond his understanding, whereas others may take it as ‘mysteries of research’ which are understood only by a few persons working amidst complicated apparatus in a laboratory. A non-scientist feels that it is a ‘subject’ whose endeavour is aimed to improve the man’s life on the earth. A business executive has the idea that it is ‘something’ which solves our day to day manufacturing and quality control problems, so that the nation’s economic prosperity keeps on improving.

Composition and Resolution of Forces

The force is an important factor in the field of Mechanics, which may be broadly defined as an agent which produces or tends to produce, destroys or tends to destroy motion. e.g., a horse applies force to pull a cart and to set it in motion. Force is also required to work on a bicycle pump. In this case, the force is supplied by the muscular power of our arms and shoulders.
