[Suppose a person's weight is evenly distributed over the four legs of a chair (person plus chair:82.0kg). The area of contact with the floor is 2.00 cm for each chair leg. Calculate the pressure on the floor for each chair leg. Now compare to the pressure exerted under a 70.0kg ice skater standing on two skates which EACH have rectangular cross sections of 25.0cm by 0.300cm. Watch out that you really use WEIGHT and, to get the correct units for pressure, use Newtons per square METER, not square cm or mm. Give your answer in Pascals and atmospheres.],
