Mechanisms 1

• A mechanism is a device that converts and input motion and force, into an output motion and force.
• Linear:

  • moving in a straight line
  • ➡️
  • eg - A train running along a straight strack
• Rotary:

  • Turning, moving around in a circle
  • 🔄
  • eg - turing a wheel
• Reciprocating:

  • Moving back and forth in a straight line.
  • ↔️
  • Sawing a piece of wood
• Oscillating:

  • swinging from side to side in an arc
  • ↩️↪️
  • eg - A pendulum swinging in a clock
• A lever is a rigid bar that pivots around a fulcrum.
• The fulcrum is the point around which the lever turns
• The load is the output force.
• The effort is the input force that you apply to move the load
• mechanical advantage= load(force in newtons) ÷ effort(force in newtons)
• FLE -

  • Fulcrum in the middle
  • Load in the middle
  • Effort in the middle
