Question

Area is indirectly proportional to the pressure. Explain this with an example. ​

Answer 1

Answer:

Try to stand on one foot, instead of two,you will feel an increased amount of pressure on the foot on which you are standing,here area is halved.

Try to compress a pillow with fingers from both sides,and then do this with palms from both sides,you will see,that pressure on pillow decreases (at the point where you put your fingers earlier) due to an increased area of your palms.

One good example is of the principle of hydraulics(Pascal's law) used in a car ramp.The piston side has a small area of pipe with water,and lift side has a big area.Now,one can raise the lift carrying thousands of kilograms, by applying normal pressure on the piston.Because,the decreased area of piston side gathers an increased amount of pressure,which is transferred to the other side .

A sharp knife cuts more effectively than a blunt knife,the sharp knife,having very small area on edges offers a large pressure on object to be cut,while blunt knife fails to do so.

Climb a 10 feet wall and throw an object on the ground so that it lands covering maximum area,and do this again by throwing the object so that it gets impact in minimum area,you will see that in second case,object receives greater damage,due to increased pressure on it.
