What are hydraulic stress and volume strain according to the text about mechanical properties of solids?
Understand the Problem
The question is asking about the mechanical properties of solids, specifically focusing on hydraulic stress, volume strain, and Hooke's law as presented in the text. It discusses the relationship between stress and strain, and how materials behave under tensile stress, leading to graphs depicting their properties.
Answer
Hydraulic stress is force/unit area; volume strain is ∆V/V.
Hydraulic stress is the internal restoring force per unit area equal to hydraulic pressure. Volume strain is the ratio of change in volume to the original volume due to hydraulic pressure.
Answer for screen readers
Hydraulic stress is the internal restoring force per unit area equal to hydraulic pressure. Volume strain is the ratio of change in volume to the original volume due to hydraulic pressure.
More Information
Hydraulic stress occurs when a fluid applies pressure evenly in all directions, altering the volume of an object. Volume strain, being dimensionless, measures the proportional change in volume.
Tips
A common mistake is confusing volume strain with tensile strain, which involves changes in length rather than volume.
