Bending Stress

Building off your beam experiment and discussion post from 3.2 – Discussion: Wing Design/Bending Stress, write a technical report outlining your experiment setup, test procedures and results. Follow the report format provided below. Include estimates of the maximum applied stress using the “bending stress equation” from Module 4. You’ll need to make a number of simplifying assumptions in order to complete the calculations. That’s fine! Just be sure to include a list of those assumptions in your paper. Given your maximum stress calculations, estimate the maximum structural strain though Hooke’s Law.

The report should be a minimum of 1,000 words and any references must be in the current APA format. You shall write the case study using the report format listed below.

• Front cover with name and detail of work
• Introduction
• Body
  • Experiment
    • Setup and materials
    • Boundary/end/support conditions and loading profile
  • Findings (experimental and theoretical)
    • Use bending stress equation (My/I)
    • “y” and “I” are calculated based upon the dimensions of your beam’s cross-section; you’ll need to estimate the bending moment (“M”) applied to your beam. For the latter, explain your thought process.
    • List assumptions made for the analysis
    • Discuss the “reasonableness” of your answer (in terms of Factor of Safety).
    • Maximum deflection (experimental measurement)
    • Bending stress analysis
    • Maximum strain estimate (Hooke’s Law)
  • Relevance
    • Within the paper, expand upon the discussion posting based upon student/instructor replies and new insights of your own.
• Summary
• References
• Appendices (calculations)
• Times New Roman – 12 point font and double lined space
