You want to examine the possibility of using a polymeric material as an artificial load
  bearing surface for articulating joints. But the deformation of this material under loading is a
  concern. You have been informed that if the material has a Poissons ratio under 0.1, then it
  can undergo further testing for this application. You are given a cylindrical sample that is 10
  mm in diameter and 3 mm in height. During compression testing, you apply a strain of 20
  in the axial direction, and the diameter of the cylindrical sample increases by 0.4 mm at its
  widest point. What is the Poissons ratio of the sample? Does it pass or fail the screening
  test?
 
  What will be an ideal response?
