    THE MEANING OF MECHANICS


    The word mechanics is derived from a Greek word meaning (contrivances) and this conveys some idea of the scope of the subject.
    Many of the (contrivances) and the fundamental principles underlying them form part of the instinctive heritage of the human race .

    Our body contains some of these contrivances , which through long ages , have been adapted by nature to our needs.

    If we lift a weight , or raise our feet from the ground in walking , we are employing MECHANISMS which are admirably adapted by nature for the purpose.

    A little child , in learning to stand and walk is contriving by his experiments in balancing.

    Two children on a sea-saw know the necessity of positioning themselves so that they may balance.
    The principles of mechanics also enter vitally into the daily work of many whether it is the bricklayer wheeling his barrow-load of bricks, the farmer pumping water from his well or the aeronautical engineer designing an aeroplane.

    The scientific study of these principles through the ages has led to the complicated mechanisms of modern times, such as the steam-engine, the motor-car, or the machine gun.

    It is important therefore that we should examine and learn to understand them and that is the principal reason for studying mechanics.

    MECHANICS may be defined as the subject in which we study the condition under which objects around us move or at rest.

    These two aspects of rest and motion of bodies have to led the division of the subject into two parts:
    (1) statics: which deals with bodies at rest.
    (2) Dynamics: which is concerned with bodies in motion.


    i hope that this would be usefull
