The relationship between force, pressure and surface area
The relationship between pressure, force and contact area is demonstrated. A Scorpion tank exerts a downward force of 80,000N, whereas a ballerina exerts only 600N. Which exerts the greatest pressure on the ground? The tank, with its large tracks and greater surface area, exerts a pressure on the ground which is seventeen times less than the ballerina on one point.
