Spring back is a term used to describe which of the following?

Spring back refers to the tendency of a material, such as conduit, to return toward its original shape after being bent. This phenomenon occurs because the material is elastic, and once the bending force is removed, there is a slight rebound effect. In the context of bending conduit, when the bender is released, the conduit may relax to a slightly looser angle than the angle it was bent to. This is an important consideration in the accuracy of bends because it can affect the final installation and the fit of the bend in various applications.

The concept of spring back is crucial for ensuring that bends are made correctly, accounting for any potential relaxation that might occur. Proper calculations and adjustments are often necessary to achieve the desired bend angle, making awareness of this tendency essential for anyone working with bending equipment.
