The Model:
This Mechanism Teaching Board uses a common A3 sized Pegboard as a backing to connect all the Mechanism Models to. The Mechanism Models provide a useful teaching resource to help students understand how mechanisms work, and how particular ones convert or reduce/increase various types of motion.
The board, once assembled, includes models of 4 different types of Cam, the 3 classes of Lever, two different Pulley setups, a simple Gear system, and a compound Gear system.
The Project:
In my classes (Engineering, ages 14-16) students learn about mechanisms and how they work, and are then asked to design and construct a toy which uses at least one mechanism. Mechanism in this context is explored as something that converts one type of motion to another (linear, rotary, osculating, reciprocating, etc). Most students design models of their mechanical toys in various CAD programs to get a visual understanding of what they need to build.
