### device | mechanism | transmission system:

Automatic transmission
* are transmissions.
* is considered luxury in Europe.
* transmission system

Vane
* Some vanes are part of oars
  - propellers
* are also waterproof, which can be a significant factor when hunting in wet weather
  - blades
  - composed of progressive branchings starting from the shaft
  - fins
* are part of arrows
  - feathers
  - missiles
* includes sections.

Various mechanism
* appear to be involved in the adsorption processes.
* cause resonances in objects subjected to electromagnetic fields.
* play a role, including the alteration of normal gut flora.

### device | mechanism:

Wheel
* Every wheel contains triangles, so no W n is bipartite.
* Most wheels have diameters
  - friction
  - lower friction
  - rubber tires
* Most wheels have solid rubber tires
  - require friction
* Some wheels are part of chariots
  - gondolas
  - pushchairs
  - strollers
  - tractors
  - tricycles
  - wheelbarrows
  - powered by engines
  - submerged in water
  - convert energy
* are a common way to reduce friction
  - all natural wood
  - always stronger when their spokes have uniform tensions
  - circular objects
  - circulars
  - forces
  - helms

  - wagons
  - parts
  - plastic
  - resin castings mounting slot car tires
  - rounds
  - the earliest tools developed by mankind to facilitate transportation
* are used for cars
  - machinery
  - rollings
  - steering
  - turning
* can be things like actual wheels, half-tracks, hovercraft or flying machines
  - have sharp edges and rusty spots
* comes in all sizes and hardnesses.
* determine how the pavement feels underfoot.
* have lower friction
  - roll friction
  - nothing to do with flying
  - rotational energy which has to come from somewhere, thus from beam
  - treads
* includes sections.
* lose energy.
* move easily over any surface, even up and down stairs.
* offer traction.
* reduce friction because only a little part of it touches the ground at one time
  - with the floor to help cars move
* rotate, sending out a circular spiral of flame and sparks.
* support weight.
* turn on axles, and springs suspend the body and absorb vibration and shock.
* work more effectively when they have a smooth road surface to travel on.
+ Lever, Types of levers, Second class: Engineering :: Tools
  * A second-class lever is where the resistance is between the effort and the fulcrum. Wheel barrows and wrenches are examples of second class levers.

Paddle wheel
* Some paddle wheels are submerged in water.
* are wheels.

Roulette
* come in many shapes.
* is curves
  - games of chance
  - located in casinos
  - military units

### device | mechanism | wheel | roulette:

Russian roulette
* deadly game in which all but one of the gun's bullets are removed.
* is albums

### device | mechanism | wheel:

Train wheel
* Most train wheels have friction.
* Most train wheels have lower friction
* are affixed to a straight axle, such that both wheels rotate in unison.
+ Axle: Engineering
  * Train wheels are affixed to a straight axle, such that both wheels rotate in unison. An 'axle' is a central shaft for a rotating wheel or gear. In some cases the axle may be fixed in position with a bearing or bushing sitting inside the hole in the wheel or gear to allow the wheel or gear to rotate around the axle. In other cases the wheel or gear may be fixed to the axle, with bearings or bushings provided at the mounting points where the axle is supported. Sometimes, especially on bicycles, the latter type is referred to as a spindle.
