Problem 51P

In a lecture demonstration, a professor pulls apart two hemispherical steel shells (diameter D) with ease using their attached handles. She then places them together, pumps out the air to an absolute pressure of p, and hands them to a bodybuilder in the back row to pull apart. (a) If atmospheric pressure is p0, how much force must the bodybuilder exert on each shell? (b) Evaluate your answer for the case p = 0.025 atm, D = 10.0 cm.

Step-by-Step Solution:

Solution to 51P Step 1 of 2 Introduction The pressure applied on a cross sectional area is equal to the perpendicular force applied per unit cross sectional area. Pressure inside the shell=0.025atm=2533.125Pa Air pressure outside the shell=101325 Pa Diameter of the shell=10.0cm=0.1m Radius of the shell=0.05m
