Strain: A measure of the intensity of deformation. Expressed in units of Length/Length
Centrically Axially Loaded Member: A structural member subjected only to loads acting through the member’s centroid along its longitudinal axis.
Normal Stress: The stress calculated using the component of the internal force in a member that acts normal to an exposed surface or cross section.
Shearing Stress: Stress calculated using the component of the internal force that acts parallel to the exposed surface.
Average Axial Strain: A measure of deformation over the length of a body. Axial strain is calculated by dividing the change in length over the body’s original length.4. Key Definitions
