A ball has a 312-mm outer diameter and a 2.7-mm wall thickness. What is the normal stress in the wall of the ball when the ball is inflated to a 110-kPa gauge pressure. The answer should be in MPa with 1 digit of accuracy. 5.31 3.1 margin of error +/- 0.1 Keep in mind that the radius you should evaluate should be the radius on the inside of the ball. (not the mid-plane radius or the outside radius).
