Mechanical Power Transmission

The following modules can be used to study mechanical power transmission in a self-paced activity where the coach can just be available for guidance as needed.  They are inspired by Yoshihito Isogawa's Power Function book: Machines & Mechanisms.  We have expanded on his original 8 modules and added a manual input crank so that a power function and power source is no longer required.
​The parts list provided should assist you in building from your own inventory or you can jump out to each link to use Rebrickable.com to accumulate a parts list for purchase.

To use the modules as a teaching tool, use the attached game boards to challenge your student to route the power transmission from input to output.  It get's more and more challenging as one input module needs to supply power to more than one output.
