Questions & Step-by-Step Solutions
If a material has a Poisson's ratio of 0.3, what does this imply?
Step 1: Understand what Poisson's ratio is. It is a measure of how much a material deforms in the lateral direction when it is stretched or compressed in the axial direction.
Step 2: Know that a Poisson's ratio of 0.3 means that for every unit of stretch in the length of the material, it will contract 0.3 units in the width or height.
Step 3: Realize that this behavior is typical for many materials, indicating that they do not just stretch but also get thinner as they are pulled.
Poisson's Ratio – A measure of the ratio of lateral strain to axial strain in a material when it is deformed.
Material Behavior – Understanding how materials respond to stress, including lateral contraction when stretched.
