Question

Pressure on a body is inversely proportional to the area of contact.
Give three examples from your daily life to demonstrate this principle.​

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.

Answer 2

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 .
