Civil Engineering QUESTION #6576
Question 1
A direct stress always produces a corresponding strain in its own direction and an opposite strain in directions perpendicular to it. This perpendicular strain is specifically termed:
  • Linear strain
  • Lateral strain✔️
  • Volumetric strain
  • Shear strain
Correct Answer Explanation
Lateral strain (also called transverse strain) is the strain induced in directions perpendicular to the applied stress. It is related to the direct (linear) strain by Poisson's ratio: \(\varepsilon_{lateral} = -\nu\,\varepsilon_{axial}\).
