If a man pushes the head of a nail with a pressure of 20 N/cm虏 over an area of 2 cm虏...?

then what is the force on the nail? What is the pressure under the point of the same nail if the point of the nail has an area of .0002 cm虏?If a man pushes the head of a nail with a pressure of 20 N/cm虏 over an area of 2 cm虏...?
P = 20 N/cm虏


A = 2 cm虏





F = PA = (20)(2) = 40 N





P = F/A = (40)/(0.0002) = 200,000 N/cm虏
