The state of elastic stretch in structural members such as rods or cables is called what?

Explanation:
Tension is the state of elastic stretch in a structural member when it is pulled along its length. When a rod or cable experiences an axial pull, it elongates slightly as the material resists the pull with tensile stress. This elongation is what we call tension. In contrast, compression shortens the member as it is pushed together; shear involves layers sliding past one another, not a change in length; and torsion is twisting about the axis. So the elastic stretch along the length under pull is tension.
