Question: Which of the following describes Poisson\'s ratio?

Options:

  1. Lateral strain / Longitudinal strain
  2. Longitudinal strain / Lateral strain
  3. Stress / Strain
  4. Strain / Stress

Correct Answer: Lateral strain / Longitudinal strain

Solution:

Poisson\'s ratio (ν) is defined as the ratio of lateral strain to longitudinal strain.

Questions & Step-by-Step Solutions

Which of the following describes Poisson's ratio?
  • Step 1: Understand that Poisson's ratio is a measure used in materials science.
  • Step 2: Know that when a material is stretched or compressed, it changes shape.
  • Step 3: Identify the two types of strain: longitudinal strain (change in length) and lateral strain (change in width).
  • Step 4: Realize that Poisson's ratio (ν) compares how much a material gets thinner when it is stretched to how much it gets longer.
  • Step 5: Remember that Poisson's ratio is calculated by dividing the lateral strain by the longitudinal strain.
