Mechatronics

Mechanical Devices

• Types of motion

  • Linear - straight line

  • Rotary - around axis 

  • Reciprocating - repeated up and down

  • Oscillating - curved swing

• Levers

  • effort - the amount of force applied by the user, also referred to as the input

  • fulcrum - where the lever pivots

  • load - the weight that needs to be moved, also referred to as the output

  • Mechanical advantage = load(N) / effort (N)

  • Classes of Levers

    • First order- Effort, Fulcrum Load eg seesaw

    • Second order - effort, Load, Fulcrum eg wheelbarrows

    • Fulcrum, Effort, Load - eg tweezers

  • Cams and followers - cam attaches to a crankshaft which rotates. The follower touches the command follows the shape moving up and down

  • Gears - can change the direction or the speed of the movement.

    • Ratio = number of teeth of driven/ number of teeth on driver

  • Pulleys - use…
