Exemplars (from the NaCCA curriculum)
1. Use charts, models or real objects to describe the features of the various types of mechanisms. 2. Use simple diagrams to illustrate the operations of the various types of mechanisms. E.g. Rack and pinion, cams, levers and linkages. 3. Discuss the advantages and disadvantages of the various types of mechanisms. E.g., Pulley system: - Advantages: No lubrication needed, quiet in operation - Disadvantage: A slip can occur 4. Watch videos on the various types of mechanisms in operation and discuss in class. E.g. The operations of the crank, cam, rack and pinion, chain and sprockets
