1. Use a T-chart to LIST the strengths and weaknesses of your design. sw AERODYNAMIC BALANCED DRAG STRONG THRUST LOW MASS LOOSE WHEELS ALIGNMENT WINDOW CUT OUT 2. Explain how EACH strength and weakness affected your results. AERODYNAMIC – BALANCED - DRAG STRONG THRUST – SPEED – ACCELERATION – PROPEL LOW MASS – THRUST – SPEED – ACCELERATION - PROPEL 3. Explain how the scientific data gathered from the wind tunnel and the triple beam balance plays a role in your dragster results. TRIPLE BEAM BALANCE = MASS - Thrust, Propel, Acceleration, Speed WIND TUNNEL = AERODYNAMICS - Drag, Fluid Friction

4. Fill in the “UNIVERSAL SYTSTEMS MODEL” of problem solving “ROAD MAP” as it relates to the dragster process you just completed. COMPLETE TABLE ON BACK Goal – Problem, Need or Want Input –7 Resources used to solve. Process – All work done to achieve solution. Output – Specific results from problem. Feedback – Information gathered to make change. (Specific changes made) 5. IDENTIFY each of the following systems as they relate to the dragster: (Answer on the open response sheet) a. Propulsion - b. Control- c. Support / Structural- d. Suspension- e. Feedback- Air compressor Fishing line Wood body Wheels & axle Balance – wind tunnel - timer
