Questions & Step-by-Step Solutions
If a material has a Poisson's ratio of 0.3, what does this imply about its behavior under stress?
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.
Step 2: Know that a Poisson's ratio of 0.3 means that for every unit of stretch in the length direction, the material will contract 0.3 units in the width direction.
Step 3: Realize that this behavior is typical for many materials, indicating they are somewhat flexible and can change shape under stress.
Step 4: Conclude that when the material is pulled or stretched, it will get thinner in the other directions.
Poisson's Ratio – A measure of the ratio of lateral strain to axial strain in a material when subjected to stress.
Material Behavior Under Stress – Understanding how materials deform in response to applied forces, including lateral contraction and axial elongation.
