motions

• Mechanical systems all have an input motion, which transforms into force to make an output motion.
• types of motion

  • rotary
  • linear
  • osculating
  • reciprocating
• linear = the movement of an object in one dimension from one place to another in a straight line
• linear motions included train and a person running
• rotary motion = the physical motion of a certain object witch is spinning on an axis of its own
• rotary motion includes wheel and record player
• osculating motion = the to and fro motion of the body about it's fixed position
• osculating can include swing and pendulum clock
• reciprocating motion = a backward and forwards movement in a straight line
• reciprocating motions include sawing machine and piston
• Linear motion moves something in a straight line, eg a train moving down a track:
• Rotary motion is where something moves around an axis or pivot point, eg a wheel:
• Reciprocating motion has a repeated up-and-down motion or back-and-forth motion, eg a piston or pump
• Oscillating motion has a curved backwards and forwards movement that swings on an axis or pivot point, eg a swing or a clock pendulum:
• types of motion

  A) rotary

  B) reciprocating

  C) osculating
