Pressure = (total force on an area) / (the area of the area)
Force = the woman's weight
Weight = (mass) x (gravity) .
Weight = (54 kg) x (9.8 m/s²)
Weight = 529.2 Newtons
Area of a circle = (π) x (radius)²
Area of the bottom of the heel = (π) x (0.46 cm)²
Area of the bottom of the heel = 0.665 cm² = 0.0000665 m²
Pressure = (force) / (area)
Pressure = (529.2 N) / (6.65 x 10⁻⁵ m²)
Pressure = 7,960,756 N/m²
Pressure = 7.96 x 10⁶ Pascals
Pressure = almost 79 atmospheres !
This is why many places don't allow spikey heels to be walked in across their floors. (Really. I'm not making this up.)
