Questions & Step-by-Step Solutions
What is the relationship between stress and strain in the elastic region of a material?
Correct Answer: Stress is directly proportional to strain.
Step 1: Understand what stress is. Stress is the force applied to a material divided by the area over which the force is applied.
Step 2: Understand what strain is. Strain is the deformation or change in shape of a material when stress is applied.
Step 3: Learn about the elastic region. The elastic region is the range of stress and strain where a material will return to its original shape after the stress is removed.
Step 4: Know Hooke's Law. Hooke's Law states that, in the elastic region, the amount of strain in a material is directly proportional to the amount of stress applied.
Step 5: Apply Hooke's Law. This means if you double the stress, the strain will also double, as long as you are within the elastic region.
