A geometric bend tracked by a fixed point-on one circle which rotates around the perimeter of another group. For example the design of this Wankel motor

a type of bend. See epicycloid, any trochoid.

In geometry, the bend traced by a place in airplane of a circle which rolls on the convex side of a fixed group.

A geometric bend tracked by a set point-on one circle which rotates all over perimeter of some other group. Examples include the form associated with Wankel engine

a type of bend. See epicycloid, any trochoid.

In geometry, the bend tracked by a spot in plane of a circle which rolls regarding the convex side of a fixed group.

A geometric curve traced by a hard and fast point on one group which rotates across the border of another group. For example the form for the Wankel engine

A kind of curve. See epicycloid, any trochoid.

In geometry, the bend traced by a place in the jet of a circle which rolls on the convex part of a fixed group.

A geometric curve tracked by a set point on one circle which rotates round the perimeter of some other group. These include the form regarding the Wankel motor

a type of bend. See epicycloid, any trochoid.

In geometry, the bend tracked by a place in plane of a circle which rolls on convex side of a hard and fast circle.
