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?
