A woman wearing high healed shoes placed about 50% of her full weight on a single heal when walking.

A) Assuming the woman weighs 530 N, what is the pressure on the ground under one heal if the area of contact per heal is 6.5 cm^2? What if this area was 1.0 cm^2?

B) How does this compare with the pressure underneath an elephant's foot? For computation, assume that a full-grown elephant weighs 37,000 N and is standing evenly on four feet. Approximate the feet as circles 38 cm in diameter.

Pressure is computed as
P = Force / Area
or
P = Weight / Area .

A) Area under one heal of woman = 6.5 cm^2 or 6.5 * 10^-4 m^2
Weight of woman = 530 N
Weight placed on single heal during walking = ...
