10. A cylinder of diameter d made from material with elastic modulus E and Poisson's ratio v, is placed inside a rigid sleeve with inner diameter d+ B, and a

uniform pressure is applied to the top of the cylinder. a) Determine the pressure that causes the cylinder to contact the sleeve. b) Find the change in height of the cylinder at this load. c) If the pressure is doubled, will the shortening double? Explain your answer.
