(of some shells) closely coiled so that the axis is obscured especially of petals or leaves in bud; having margins rolled inward
a (L involutus, rolled up) leaves having the edges rolled inwards at each side, toward the adaxial side
If C is a curve and C' is its evolute, then C is called an involute of C' Any parallel curve to C is also an involute of C' Hence a curve has a unique evolute but infinitely many involutes Alternatively an involute can be thought of as any curve orthogonal to all the tangents to a given curve
Rolled inward from the edges; said of leaves in vernation, or of the petals of flowers in æstivation
(n) A curve defined as the spiral trace of a point on a flexible line unwinding from around a line, circle, or polygon The contacting surfaces between gear teeth are designed as involutes
A spiral curve generated by a point on a chord as it unwinds a circle or a polygon
The involute gear profile is the most commonly used system for gearing today. In an involute gear, the profiles of the teeth are involutes of a circle. (The involute of a circle is the spiraling curve traced by the end of an imaginary taut string unwinding itself from that stationary circle called the base circle.)
