MECHANISMS - Coggle Diagram

- - - - Movable connections:Are used to connect shafts that can move along the axles or at an angle to each other.There are two main types:Oldham joints and Cardan joints.
      - Fixed connections:Are used to make permanent connections between axles and shafts.
      - Supports:Bushings and bearings.
        
        Bearings:Are made up of two concentric rings with balls or rollers between them.
        
        Bushings:The axle or the shaft is inserted in a plain circular piece that is placed inside a housing to provide a bearing surface
- - - - Transporting people from A to B
      - lifting and carrying objects.
      - entertaining the children
      - telling the time
    - - The driving force can be a spring, an electric motor or our own muscles.
        
        Mechanisms are devices that transmit and convert forces and motion from a driving force or input element to an output element.They allow us to carry out certain tasks more easily and more efficiently.
        
        Classification of Mechanisms
        
        Controlling and regulating motion
        
        Joining elements
        
        Transforming motion
        
        Rotary to linear
        
        rotary to recipocrating.
        
        Storing energy
        
        Transmitting motion
        
        Linear
        
        rotary
- - - - Types of levers:These are classified on three types:Class 1,Class 2 and Class 3 based on their relative postion of the lever,the effort applied and the resistance.
        
        Fixed pulley:A fixed pulley is a wheel that has a groove around it into which a rope,chain or belt fits.I.Uses:Well and gym equipent for example.
        
        Movable pulley:A moveable pulley is a set of two pulleys,one is fixed while the other can move in a linear direction.
        
        Compound pulley:This is a system of fixed and moveable pulleys,often called block and tackle.Uses:Lifts,good lifts and cranes.
