MECHANISMS - Coggle Diagram

- - - - this uses a pinion that is small cogwheel, mounted on a rack that is a toothed belt or bar
    - - this consists of a bolt or theaded bar and a nut that has the same interior diameter as the diameter of the bolt
    - - a crank is a bar attached to an axle that is used to turn it. winch and crank handle system consists of a drum that rotates and a crank handle that allows to pull or lift objects
  - - - this is composed of a crank and rod called a connecting rod or link
    - - this is a set of connecting rods attached to a jointed axle. Each of the joints of the axle acts a a crank
    - - this is a basically a rotating object that pushes a follower a ir moves. We can change the shape and the usable profiles
    - - this consist of a wheel with an offcentre rotation axle tht doesn´t coincide with the centre of its circumference
- - - - a lever is a rigid bar that is supported by a fulcrum
    - - is a wheel that has a groove around it into which a rope chain or belt fits
    - - a movable pulley is a balance when it satisfies this equation
    - - this is a system of fixed and moveable pulley, often called block and tackle
- - - - friction drives are made up two or more wheels that are in contact. The first wheel is called primary drive wheel. when it moves it turns or drives the second or output wheel
    - - they consist of two pulleys or wheels that are a certain distance apart. Their axles are parallel and they rotate simultaneosly due to effect of the belt
    - - cogwheels are sets of wheels that have teeth called cogs. They transmit a rotary motion between the two connected axles, which gears can be parallel, perpendicular or oblique.
    - - this is a screw that moves a helical cogwheel tht is set perpendicular to the screw.
    - - these are two cpgwheels with parallel axles that are certain distance apart, they rotate simultaneously by means of a metal chain or a toothed belt
    - - this is a system of more than two gears, connected together as show in the diagram. the rotary of the first wheel drives the secondwheel and so on
    - - is a system of pulleys or wheels,with a belt formed by more than two wheels
