Motion

1
Motion

• Transmission
• Transformation

2
Mechanical Systems

• Combination of 2 or more simple machines
• Provide mechanical advantage
• Easier to move loads
• Transmit/transform motion
• What is the difference between transmission and
  transformation?

3
Transmission

• 4 types of motion transmitted by mechanical
  systems from one object to another
