Multi-body systems
Gears
- Larger gear - > slower spin
- Accelerations - > tangential are equal but centripetal are not
- Opposite direction
Application alert!
Four-bar linkages uses multi-body systems by combining several members to create a mechanism.
Four-bar linkages are a prominent example of a multi-body system.
Heads up!
Gears builds on this content in mechanism design.
Gears are common mechanical elements that can transmit or transfer power, change the direction or orientation of a shaft, or synchronize two shafts.
Standard sign convention
- \( \omega_{1z} \) and \( \omega_{2z} \) have opposite signs (the gears rotate in opposite direction)
- Smaller gears rotate faster
Example: Rotating gears. #rkc-gsc
Example: Rotating gears with chain. #rkc-csc
