This guide continues the process of guiding students not only in designing and building an excellent dragster but also in understanding the science and technology principles that make this happen.
Production and Fine Tuning delves into the importance of carefully aligned axles, quality paint finishes, and more topics that go beyond shaping and basic construction. Some of the principles explored are:
- Alignment and drift
- Rolling and sliding friction
- Aerodynamic drag
- Specifications and trade-offs
- Symmetry
Student materials in this guide are reproducible for distribution in your classroom. Use this guide as a supplement or use the series as the base for an engineering design course.
Equipment and materials needed to complete guide activities include a CO2 Dragsters – Getting Started Package (kits, launcher, and more), straws, modeling clay, digital scale, Roll Test Ramp, measuring tape, drill press or hand drill with 3/16" bit, spring scale, meterstick, shaping tools (for example, coping saw and rasp), dragster body blanks, try square or drafting right triangle, C-clamp, protractor, pulley, spray paint, and standard classroom tools and materials. Note: This list is for all activities; individual activities don’t require all listed materials.
