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:
“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)
“The latest creed that has to be believed
And entered in our childish catechism
Is that the All’s a concept self-conceived,
Which is no more than good old Pantheism.”
—Robert Frost (1874–1963)
“By speaking, by thinking, we undertake to clarify things, and that forces us to exacerbate them, dislocate them, schematize them. Every concept is in itself an exaggeration.”
—José Ortega Y Gasset (1883–1955)
