Strength and Stiffness Characteristics: Exercise 2

A solid circular bar has a diameter of 14 mm and length of 26 cm. As a result of a tensile axial load its diameter changes to 13.98 mm while its length increases to 26.12 cm. Determine

  1. the axial strain in the bar.
  2. the Poisson's ratio of the corresponding material.
