### shaft:

Axle
* Enter number of axles for trucks, tractors, and trailers.
* Some axles are part of bicycles
  - bikes
  - tricycles
* also house and support the differential, shafts, and wheels that propel the vehicle.
* are an important structural component of a wheeled vehicle
  - really tubes that hide hydraulic pumps, servos, and lines
  - rods that connect wheels and the whole unit is connected to a vehicle that moves
* connect to wheels.
* have advantage.
* includes sections.
+ Axle, Vehicle axles: Engineering
  * Axles are an important structural component of a wheeled vehicle. The axles maintain the position of the wheels relative to each other and to the vehicle body. Since for most vehicles the wheels are the only part touching the ground, the axles must bear the weight of the vehicle plus any cargo.

Camshaft

* is belt driven, reducing weight, number of parts, gear wear and noise
  - belt-driven, reducing weight, number of parts, gear wear and noise

Hair shaft
* Most hair shafts reflect light.
* become thin and break off as they exit the scalp.
* begin to emerge but remain trapped under a skin layer until close to birth.
* emerge from tiny follicles in the skin.

### shape:

Alpha shape
* describe the shape of a finite set of points.
* formalize the intuitive notion of shape.
* generates a family of shapes according to the selected alpha parameter.

### shape:

Angle
* Every angle has a bisector
  - exactly one bisector
  - inscribed in a semicircle right angle
* Identify the terminology associated with points, lines, planes, and angles.
* are always in degrees
  - congruent if their measures, in degrees, are equal
  - coterminal if they have the same terminal side
  - crucial as it represent more than sight or what one sees with the physical eyes
* are in degrees, arcminutes and arcseconds or in decimal degrees
  - radians
  - measure in radians

* point of view

Dihedral angle
* can be tricky to visualize.
* refers in general to the angle between two planes.
