3. A 175-lb woman stands on a vinyl floor wearing stiletto high-heel shoes. If the
heel has the dimensions shown, determine the average normal stress she exerts on
the floor and compare it with the average normal stress developed when a man
having the same weight is wearing flat-heeled shoes. Assume the load is applied
slowly, so that dynamic effects can be ignored. Also, assume the entire weight is
supported only by the heel of one shoe.
Solution:
- For Stiletto shoes o=869 psi
- For Flat-heeled shoes o=50.5 psi
