Pressure. Illustration showing a foot wearing a shoe with a stiletto heel, and an elephant's foot. The elephant's foot exerts a larger force, because the elephant is heavier, but the stiletto heel exerts a larger pressure. This is because the weight of the human wearing the shoe is acting on the tiny area of the heel, whereas the elephant's weight is spread across four feet, and each foot has a large surface area. Pressure is calculated by dividing the force (or weight) by the area over which it is acting. | |
