Question

PRESSURE AND ITS APPLICATIONS.
THOSE WILL GIVE BEST AND PROPER ANSWER. I'LL MARK AE BRAINLIST.
ANSWER SHOULD NOT FROM INTERNET.

Answer 1

Hey dear ur answer is here....


presure is the force which applied the unit area of a container.Pressure is widely used in our daily life. From drinking straws to flying an airplane, we are surrounded by pressure. When a vacuum cleaner is switched on, it sucks out the air inside the cleaner, causing the pressure inside the cleaner to become low.

Answer 2

To measure and describe the effect of the force acting on a surface, we need a quantity that takes into account the force applied as well as the area over which it is applied . such a quantity is PRESSURE. pressure is defined as the force exerted per unit area .

it is clear from this that is Malaria over which a force acts, the greater is the Treasure, and, therefore, the greater is the effect of the force .




application of force in daily life
1) have you ever tried to run on sand? It is difficult because your feet sink into the sand .a camel is able to move fast on sand because it has flat broad feet full . this increases the area of contact with the sand . hence , the pressure
exerted by camel on the sand is reduced and the camels feet sink much less in sand .

2) trucks meant to carry heavy loads have eight rather than four tyres to increase the area of contact with the road. this reduces the pressure on the tyres
