MECHANISMS, L=PxZxN - Coggle Diagram

- - - - F=R/2 x N
    - - F=R/2eN
- - - - Mechanisms for controlling and direction
      - Mechanisms that store energy
      - Connecting mechanisms
      - Supports: bushings and bearings
- - - - The first wheel is called the primary drive wheel. When it moves, it turns or drives the second or the output wheel.
      - NxD=N2XD2
    - - Are sets of wheels that have teeth called cogs
      - NxZ=N1XZ1
      - Worm gear
        
        Thisn is a crew that moves a helical cogwheel tht is set perpendiular to the screw
        
        N wheel is the N of screw multiplicated tothe N of grooves devided in the N of the wheel
    - - They consist of two pulleys or wheels thgat are certain distance apart
    - - This is a screw that moves a helical cogwheel that is set perpendicular to the screw
    - - These are two cogwheels with pararel axles that are a certain distance apart
      - they rotate simultaneosuly by means of a metal chain or a toothed belt stretched over both wheels
      - To calculate the ratio between the rotation velocity of the drive wheel and the driven wheel use the same formula of the gear mechanisms
      - Gear train
        
        This is a system of more two gears, connected together
        
        The gear ratio between the drive wheel and the driven wheel depends on the number of geared theeth in this system
        
        N/N =Z1xZ2/Z3XZ4
    - - The gear ratio between the drive wheel and the driven wheel depends on the relative size of the pulley in the system
      - N1/N2=D1xD2/D3xD4
      - There are three types the multypling system, the constant and the reducing systems
- - - - Rack and pinion system
      - The ratio between the number of rotations of the pinion and the velocity of the movement of the rack
    - - This consist of a bolt and a nut that has the same interior daimater as the diamater of the bolt
    - - A crank is a bar attached to an axle that is used to turn it
      - A winch and crank handle system consists of a drum that rotates and a crank handle that allows to pull objects
