The Abbott-Firestone curve was first described by Ernest James Abbott and Floyd Firestone in 1933. [3] [4] It is useful for understanding the properties of sealing and bearing surfaces. It is commonly used in the engineering and manufacturing of piston cylinder bores of internal combustion engines. [5]
English: Dependency between roughness profile (left), amplitude probability (center) and Abbott-Firestone curve (right), also called the Bearing Area Curve (BAC). Deutsch: Abhängigkeit zwischen Rauheitsprofil (links), Amplitudenverteilung (mitte) und Abbott-Firestone-Kurve (rechts), auch Traganteilskurve genannt.
Sketches depicting surfaces with negative and positive skew. The roughness trace is on the left, the amplitude distribution curve is in the middle, and the bearing area curve (Abbott-Firestone curve) is on the right.

The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.
In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
It is the first international standard taking into account the specification and measurement of 3D surface texture. In particular, the standard defines 3D surface texture parameters and the associated specification operators.
