Q: What is Poisson's ratio?
Solution:
Poisson's ratio (ν) is defined as the ratio of lateral strain to longitudinal strain.
Steps: 6
Show Steps
Step 1: Understand that when a material is stretched or compressed, it changes shape.
Step 2: Identify the two types of strain: longitudinal strain (change in length) and lateral strain (change in width).
Step 3: Longitudinal strain is how much the material stretches or compresses in the direction of the force applied.
Step 4: Lateral strain is how much the material changes in the direction perpendicular to the force applied.
Step 5: Poisson's ratio (ν) is calculated by dividing the lateral strain by the longitudinal strain.
Step 6: The formula for Poisson's ratio is ν = lateral strain / longitudinal strain.
