lever and pulley




'Whatever man can imagine ,he can achieve because God dwells in man" Sri Aurobindo

Archimedes the father of modern science said,"Give me  a lever and I can lift the world".
The lever and the pulley hold the key to power free engineering.The lever principle can be used in the automobiles,agriculture and other manufacturing units while the pulley can be used in the construction and irrigation activities.Proper application of the lever and the pulley can lead to conservation of energy and also generate employment.
A study of Leonardo da Vinci's drawings can give impetus to reverse engineering and better designing of ships,aircraft and houses.
