1) WHY A CAMEL CAN RUN EASILY IN A DESERT.

2) WHY AN ARMY TANK RESTS UPON CHAINS.

3) WHY VEHICLES HAVE WIDER TYRES.

4) WHY CUTTING TOOLS HAVE SHARP EDGES.

5) WHY SCHOOL BAGS HAVE WIDER STRAPS.

6) WHY NAILS AND PINS HAVE POINTED ENDS.

7) WHY WIDE WOODEN SLEEPERS ARE KEPT BELOW RAILWAY LINES.

8) WHY DO BULDINGS HAVE WIDE FOUNDATION.

ALL ANSWERS MUST BE SPERATE,CLEAR AND CORRECT.PLS.

1)surface area of their feet is larger thus pressure is decresed ,therefore they can easily walk on sand

2)armt tannks are very heavy ,thus they rest upon chain/belts to increase the surface area,so that they don't get sink in their way.

3)in order to increase the surface area so that pressure on road decreases.

4)they have got sharper edges to decrease the surface area,this will increase the pressure and fruits will easily cut.

5)to increase the surface area, so that pressure on our shoulder and colloer bone is decreased,while if

we use thin string it can cut our shoulder's and cause lower back pains.

6)this will decrease the surface area thus pressure will increase and it will get easily

stuck into the wall.

7)railway tracks are very small in surface area ,thus wooden sleppers are place below them ,so that when train passes through them pressure is distributed over large area and thus tracks do not collide.

8)this will increase the surface area thus pressure exerted by whole bulding will be distributed over large are and their will be a stable region.
