Answer to Question #37463 in Molecular Physics | Thermodynamics for EAR

Question #37463
In a classroom demonstration, a 79.2-kg physics professor lies on a "bed of nails." The bed consists of a large number of evenly spaced, relatively sharp nails mounted in a board so that the points extend vertically outward from the board. While the professor is lying down, approximately 1950 nails make contact with his body.

If the area of contact at the head of each nail is 1.26 × 10 –6 m2, what is the average pressure at each contact?
