NB: 1N/m2 = 1Pa
Using the Formula
Calculate the pressure generated by an ordinary shoe heel (person of mass 40kg, heel 5cm x 5cm), an elephant (of mass 500kg, foot of 20cm diameter) and a high-heeled shoe (person of mass 40kg, heel area 0.5cm2). Which ones will damage a wooden floor that starts to yield at a pressure of 4000 kPa?
1. Ordinary shoe heel
Clearly one can see that the high-heeled show will do the most damage to the floor.
