A nail has 2metre square at one end,1/100m^2 and at the other end.  a force of 1000g. weight is applied on the first end calculate the pressure avthing on the wall? Value of g=10m/sec^2 
Asked by ramadevi.vasi123 | 17 Feb, 2020, 06:30: AM
Expert Answer
The area of first end of nail is 2 m2  
Area of other end is 1/100 = 10-2 m2 = 0.01 m2 
Force applied = 1000 gwt = 1000 × 10 = 10000 N ...(Since, g =10 m/s2)
Pressure is applied at first end. This means other end whose area is 0.01 m2 is in contact with the wall. 
Thus, the pressure acting on a wall is 
P = Force/ Area = 10000/0.01 = 1000000= 106 N/m2

We say that pressure is defined as the amount of force exerted on an unit area and if the area is decreased, pressure increases For example an iron nail would be applying more pressure than any other thing let's say 100 N per m square but the question is an iron nail doesn't cover an area of m square so why do we say 100 N per m square
