Core Skills Analysis
Mathematics
- Applied geometry and trigonometry to calculate lift angles, bracket lengths, and clearances for the truck suspension.
- Used proportional reasoning and scaling in CAD to convert real‑world measurements into accurate digital models.
- Performed algebraic calculations for material cost estimates, including volume, weight, and surface area of steel components.
- Analyzed force vectors and torque requirements to ensure the lift kit can support the truck's weight, meeting CCSS.MATH.CONTENT.HSN-VM.C.6.
Science (Physics/Engineering)
- Investigated material properties (tensile strength, yield point) to select appropriate steel grades for safe load bearing.
- Explored concepts of static equilibrium, leverage, and torque while designing the lift mechanism.
- Conducted informal stress‑strain analysis to predict how the fabricated brackets would behave under real‑world loads.
- Integrated the engineering design process—problem definition, prototype testing, and iterative improvement—aligned with NGSS HS-ETS1‑2.
Technology & Engineering
- Created a complete CAD assembly, learning industry‑standard software tools for 3D modeling and drafting.
- Developed hands‑on welding skills, practicing joint types (fillet, groove) and proper safety protocols.
- Coordinated a small‑scale production workflow: cutting, bending, welding, and finishing metal parts.
- Documented the build with technical drawings and a bill of materials, mirroring professional engineering documentation practices.
Language Arts
- Wrote a detailed project report that described objectives, design calculations, and step‑by‑step construction procedures.
- Interpreted technical schematics and welding symbols, strengthening the ability to decode complex visual information.
- Communicated findings and challenges verbally during a presentation, practicing clear, organized oral exposition (CCSS.ELA-LITERACY.SL.HS.4).
- Revised the report using peer feedback, applying conventions of academic writing and proper citation of sources.
Tips
To deepen the learning, have the student prototype a scaled‑down lift kit using cardboard or foam board and test its stability on a model truck, then compare results to the full‑size calculations. Next, introduce a budgeting exercise where they track real material costs versus their earlier estimates, discussing economic decision‑making. Invite a local welder or engineer for a Q&A session to connect classroom theory with industry practices. Finally, challenge the student to create a short instructional video that walks viewers through the CAD design and welding steps, reinforcing both technical knowledge and communication skills.
