The heels on a pair of women's shoes have a radius of 5 cm at the bottom. if 30% of the weight of a woman 480N is supported by each heel, find the stress on each hee.
.3 * 480 N = force on a heel
area of heel = pi (.05)^2
compressive stress = force/area
in Newtons/meter^2 which is Pascals
I am assuming the heel is round and not for example semicircular.
