Question
As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. This creates quite a large pressure on the ground - in fact, in the early days of commercial flight, women were not allowed to wear high-heeled shoes because aircraft floors were too thin to withstand such large pressures.
Randomized Variables
m = 65 kg
A = 1.35 cm2
100% Part (a) Calculate the pressure, in pounds per square inch, exerted on the floor by the heel if it has an area of 1.35 cm2 and the woman

Explanation / Answer
pressur = force/ area = mg/area
pressur = (65*9.8)/(1.35e-4) = 4.72e6 Pa
1 pound square inch = 1.45*10^-4
pressure = 685 pounds per square inch
