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

Which is no more than good old Pantheism.”
