Explain reasons of below mentioned
1. Our body experience high amount of atmospheric pressure, still our body does not get puckered.
2. Why are strips of the school bags made thicker and broad.
3. Tyres of heavy vehicles Eire made very thick
4. Divers wear a metal armor while diving in sea.

4. Divers wear a metal armor while diving in sea.
1. Air of atmosphere exerts so much pressure on human body that it experiences approx. 15000 kg of weight force still our body does not get puckered, because pressure in our body balances the air pressure.
2. Strips of school bags hanged on shoulders are made thick, so that their contact area gets increased and therefore pressure exerted on the shoulder becomes less, and bags can be carried easily by children on their shoulders.
3. Pressure exerted on roads or land, is expressed by the ratio of force and contact area of the same. Due to thickness of tyres, contact area gets increased, therefore pressure exerted on roads/land becomes less. Therefore due to less pressure, type does not get inside the mud on the road and vehicle moves easily.
4. When you go deep inside the water, pressure increases. Therefore body of the divers will not able to stand with pressure when they go deep inside the sea. With the help of a metal armor, pressure gets exerted on this metal shield rather than on body of the diver. Hence divers can easily go inside the sea.
