    • What does the term 'structural fatigue' refer to?

  • The ability of a structure to resist bending over time
  • The collapse of a structure under normal operating conditions
  • The breaking down of a structure during a load test

    Study Notes

    Health Impacts

    • Cardiovascular Disease: Conditions affecting the heart or blood vessels.
    • Obesity: A condition where the body has excessive fat.
    • Healthy Fats: Good fats (e.g., avocados, nuts, seeds, fatty fish).
    • Tooth Decay: Rotting of teeth, often due to high sugar intake.
    • Type 2 Diabetes: A condition impacting the body's sugar processing.
    • Insulin: Hormone regulating glucose (sugar) absorption.
    • Glucose: Sugar.
    • Osteoporosis: Bone tissue loss/holes in bones.
    • Allergies: Negative reactions to substances like food, dust, or fur.
    • Anaphylaxis: Life-threatening allergic reaction (difficulty breathing, shock).
    • Cancer: Uncontrolled growth of bad cells. Prevention includes healthy weight, avoiding cigarettes/alcohol, and a healthy diet.
    • Antioxidants: Substances protecting cells from damage.
    • Key Foods for Health: Specific foods from worksheets/handouts are important.

    Structures

    • Classifying Structures:
      • Solid: Single piece of solid material.
      • Frame: Connected pieces like a skeleton.
      • Shell: Hollow structure using less material.
      • Combination: Combining shell, frame, and solid. (Example: a house).
    • Internal & External Forces:
      • External: Forces from outside (e.g., gravity, water pressure, wind).
      • Static: Unchanging force (weight).
      • Dynamic: Changing force.
    • Preventing Structural Failure: Designers use these approaches to reduce failure risk.
      • Designing for Loads: Making structures strong enough to support expected weights.
      • Designing for Safety: Meeting safety standards and requirements (e.g., building codes).
      • Designing for Efficiency: Using the fewest resources while maintaining strength and safety.
      • Sensors: Devices detecting early problems like structural weaknesses or vibrations.
    • Structural Strength:
      • Shapes: Triangles are strong.
      • Components: Pillared, arched structures add strength.
      • Materials: Different materials have varying strength and flexibility.
    • Centre of Gravity: Point balancing the structure's weight.
    • Stability: Structure's ability to resist forces.
    • Product Design:
      • Recall: When a product issues arise and is pulled from shelves.
      • Ergonomics: Designing products for comfortable and efficient use.
      • Symmetry: Balanced design appearing the same on both sides.
    • Structural Issues:
      • Stress: Bending over time.
      • Fatigue: Cracking due to forces.
      • Failure: Complete collapse caused by stress or fatigue.
