Core Skills Analysis
Mathematics
- Applied geometry by measuring and drafting precise angles and dimensions for the lift kit components in CAD.
- Performed unit conversions and calculations to determine material thickness, bolt spacing, and overall weight of the finished kit.
- Used algebraic formulas to estimate load capacity and stress on the fabricated parts, ensuring the lift kit meets safety margins.
- Created a cost analysis spreadsheet, applying percentages and totals to budget for metal, welding rods, and consumables.
Science
- Explored principles of physics such as torque, leverage, and force distribution when designing a lift kit that raises a truck’s chassis.
- Investigated material properties (e.g., tensile strength, corrosion resistance) to select appropriate steel grades for safe fabrication.
- Conducted informal experiments by testing weld strength and joint integrity, linking observations to concepts of heat transfer and metallurgy.
- Applied the engineering design process, iterating prototypes based on observed performance and scientific reasoning.
Technology & Engineering
- Created a detailed 3‑D model of the lift kit using CAD software, translating a conceptual sketch into a manufacturable design.
- Learned proper welding techniques (MIG/TIG) and safety protocols, integrating hands‑on shop skills with digital design.
- Followed a step‑by‑step fabrication workflow: cutting, machining, welding, and finishing, demonstrating project management skills.
- Interpreted technical drawings and schematics, converting them into real‑world dimensions and assembly sequences.
Language Arts
- Documented the design process in a written report, organizing sections for objectives, methods, results, and reflections.
- Interpreted technical jargon and specifications from CAD libraries and welding manuals, enhancing reading comprehension of specialized texts.
- Communicated project outcomes verbally and in writing, practicing clear, concise explanations for peers or instructors.
- Created a labeled parts list and bill of materials, honing skills in technical vocabulary and precise description.
Tips
To deepen the learning, have the student compare the lift kit design with an existing commercial kit and write a side‑by‑side performance analysis. Next, set up a small‑scale stress test using weights and a simple load cell to collect real data, then graph the results and discuss any discrepancies with the original calculations. Incorporate a cross‑disciplinary session where the student presents the project to younger learners, reinforcing communication skills while mentoring. Finally, challenge the student to redesign the kit for a different vehicle type, encouraging creative problem‑solving and application of the same engineering principles.
