USES OF SPRINGS


Some important uses of springs are as follows;


1: To absorb energy due to shock or vibration.


2: To apply forces as in brakes, spring loaded valves or plunger of dividing head.


3: To control motion by maintaining contact. between two elements such as cam and follower.


4: To measure forces y linear deflection such as in spring balance.


5: To store energy as in wall clocks and children toys.
