The pressure exerted on the floor by a person’s shoe heel varies in direct proportion to his or her weight, and inversely proportional to the square of the diameter of the heel. Find the particular equation when a pressure of 29.1 psi results from a man weighing 175 pounds wears shoes with a 2.55 inch diameter heel. Using the particular equation you find, predict the pressure (to the nearest psi) under the ¼ inch spiked heel of a woman weighing 125 pounds
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
