### device | mechanism:

Gyroscope
* Some gyroscopes are part of shipwrecks
  - steamers
* allow the child to understand the challenge of gravity and basic principles of physics.
* are also an essential part of spaceships
  - disks with an axle through the centre
  - like motion detectors
  - mechanical devices
  - quite delicate electronic instruments and various things can happen
  - wheels
* help keep rockets aimed in the right direction.
* measure the angular rate of rotation of a vehicle.
* resist attempts to change the angular position of the axis of the spin.
* try to keep spinning in the same direction.
* use rotating bodies to sense shifts in the direction of movement.

### device | mechanism:

Hydraulic system
* Many hydraulic systems operate outdoors.
* are mechanisms
  - used for moving very heavy things, like in cranes, excavators, or bulldozers
* contain an operating fluid.
* rely on an incompressible fluid to transmit force.
* transmit power to operate the brakes and, in some cases, the steering system.
+ Actuator, Linear Actuators: Machines
  * Linear actuators are actuators that move in a straight line. They can be made to move by electricity, or by pushing water or air very hard. Hydraulic systems are used for moving very heavy things, like in cranes, excavators, or bulldozers.

Important mechanism
* Most important mechanisms contribute to evolution.
* Some important mechanisms contribute to excretion
  - fecal excretion

Mechanical device
* Many mechanical devices can aid mobility until the person recovers
  - help overcome handicaps caused by weakness
  - depend on computers for operation
* Most mechanical devices have applications
  - bearings as important functional components
  - utilize bearings as important functional components
* are devices
* can give a false sense of security
  - help patients with obstruction breathe better

### device | mechanism | mechanical device:

Carburetor
* All carburetors work under the basic principle of atmospheric pressure.
* Most carburetors have different jets and circuits for different throttle openings and flow speeds.
* are mechanical devices
  - part of fuel systems

Clip
* are blows
  - cuts
  - fasteners
  - jewelry
* are located in desks
  - discount stores
  - hair
  - office buildings
  - offices
  - television shows
* are used for binds
  - dogs
  - hairstyles
  - holdings
  - poodles

### device | mechanism | mechanical device | clip:

Paper clip
* are clips.
* are located in desktops
  - drawers
* are located in file cabinets
  - folders
  - hospitals
  - universities
  - metal
  - objects
  - the larval stage of coat hangers
  - wire
* can abrade or scratch the surfaces of prints or negatives.
+ Paper clip, Shape: Stationery
  * There are many different kinds of paper clips. Some have  ends instead of round ones. Some have a bent end. This was done so that it is easier to put paper in. Some of them have wires with bumps that allow them to hold the paper better. Some paper clips are made to look good. They are sometimes in a triangle or a circle.

### device | mechanism | mechanical device:

Compressor
* Most compressors have an air intake filter, which discolours as it gets clogged.
* affect file size, playback speed and image quality.
* are continuous flow processes, and can be either axial or radial
  - integral components of all heating and cooling systems
* can provide air for power tools or change gasses to liquids for easier transport.
* come in various types.
* continue to provide heat.
* running against excessive discharge pressures are prone to premature failure.
* use moving pistons to pump in air at low pressure and pump it out at high pressure.
