Questions & Step-by-Step Solutions
In which of the following scenarios does a material exhibit plastic deformation?
Step 1: Understand what plastic deformation means. It is when a material changes shape permanently after being stressed.
Step 2: Learn about stress. Stress is the force applied to a material divided by the area over which the force is applied.
Step 3: Identify the yield point. The yield point is the maximum stress that a material can withstand without permanent deformation.
Step 4: Compare the applied stress to the yield point. If the applied stress is greater than the yield point, the material will undergo plastic deformation.
Step 5: Look for examples. Scenarios where materials bend, stretch, or change shape permanently after being pushed or pulled are examples of plastic deformation.
