👉 Epinette is a concept in mechanical engineering, specifically used to measure the thickness of a material or structure. It is often denoted by the symbol "ep" and represents the distance between two parallel planes that meet at a specified angle. The definition of epinette is: 1. Epinette thickness = Total length of a series of parallel planes that intersect at a 45-degree angle 2. Epinette thickness = Thickness of material or structure measured in millimeters The
