Methods

`Static` addGear

addGear(p, r1, depth, numTeeth, outPercent, inPercent, startEdges): void
Adds a gear shape set of edges to the given Polygon. The shape of a tooth is determined as follows. A tooth has 4 edges, which we call: up-slope, out-edge, down-slope, and in-edge.
```
    ___
   /   \
  /     \___
```
Let the horizontal span be 100%, then each of the 4 tooth edges has a percentage. For example in the above diagram, the percentages are roughly 25% each. The percentages for the out-edge and in-edge are supplied as parameters. The remainder is split evenly between the up-slope and down-slope.
Parameters
- p: Polygon
  the Polygon to add the gear to
- r1: number
  the inside radius of the gear
- depth: number
  the depth (or length) of the teeth
- numTeeth: number
  number of teeth
- outPercent: number
  the percentage of tooth that is extended (the out-edge)
- inPercent: number
  the percentage of tooth that is not extended (the in-edge)
- startEdges: Edge[]
  adds to this array the starting edge of the gear
Returns void
- Defined in sims/engine2D/GearsConfig.ts:69

`Static` makeGear

makeGear(radius, startEdges, opt_name?, opt_localName?): Polygon
Parameters
- radius: number
- startEdges: Edge[]
  adds to this array the starting edge of the gear
- Optional opt_name: string
  name of the Polygon
- Optional opt_localName: string
  localized name of the Polygon
Returns Polygon
- Defined in sims/engine2D/GearsConfig.ts:40
