These exercises will assist students to apply algebra, geometry and trigonometry to create a spur gear, tapered gear and a gear assembly. There are three lessons that introduce the concept of a design that is controlled by geometry and equations, has students continually re-work a design, evolving it from a simple model to an advanced one, capable of producing a wide range of parts, allow students to solve certain design problems on their own. To complete the lesson the students must use these skills that they have learned. Many high-school students can do the math, but have never seen much use for it. Several of the steps cannot be completed unless the student thinks in geometric terms. The idea is to encourage the students to think. Contributed by Dale Gibson.
