Concept
In terms specific to screws, the helix angle can be found by unraveling the helix from the screw, representing the section as a right triangle, and calculating the angle that is formed. Note that while the terminology directly refers to screws, these concepts are analogous to most mechanical applications of the helix angle.
The helix angle can be expressed as:
where
- l is lead of the screw or gear
- rm is mean radius of the screw thread or gear tooth

Famous quotes containing the word concept:
“Modern man, if he dared to be articulate about his concept of heaven, would describe a vision which would look like the biggest department store in the world, showing new things and gadgets, and himself having plenty of money with which to buy them. He would wander around open-mouthed in this heaven of gadgets and commodities, provided only that there were ever more and newer things to buy, and perhaps that his neighbors were just a little less privileged than he.”
—Erich Fromm (1900–1980)
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
“Obscenity is a moral concept in the verbal arsenal of the Establishment, which abuses the term by applying it, not to expressions of its own morality, but to those of another.”
—Herbert Marcuse (1898–1979)
