MECHANISMS - Coggle Diagram

- - - - Constant system=>Velocity remains constant
      - Reducing system=>Velocity is reduced
      - Multiplying system=>Velocity is increased
- - - - By compression
      - By traction
      - By torsion
  - - - Oldham joints
      - Cardan joints
  - - - They are used to reduce velocity
      - Disc brakes
      - Band brakes
      - Drum brakes
- - - - P is the distance between two consecutive teeth in millimetres
      - Z is the number of teeth in the pinion
      - L is the velocity of the rack's movement in millimetres per minute
      - N is the number of rotations per minute of the pinion
      - L=PxZxN
    - - Uses: Presses, taps, car jacks...
      - It consist of a bolt and a nut that has the same interiordiameter as the diameter of the bolt
    - - r is the radius of the winch and d, the length of the crank handle
      - F is the force applied and R, the resistance
      - Fxd=Rxr=>F=Rx((Rxr)d)
  - - - It's a set of connecting rods attached to a jointed axle
      - Uses: Combustion engines and sewing machines
    - - We can change the shape and and the usable profiles
      - A set of cams fixed on the same axle is called a camshaft
      - It's a rotating object that pushes a follower as it moves
    - - It can transform reciprocating motion or oscillating motion into rotary motion
      - It's composed by a crank and a rod called a connecting rod or link
    - - The distance between the centre of the circumference and the rotation axle is called eccentricity
      - Uses: Sewing machines and windscreen wipers
      - It consists of a wheel with an off-centre rotation axle
