  1. Mechanical Fatigue is caused by:
    Cyclic stresses occurring over a long period of time
  2. Which of the following materials are affected by Mechanical Fatigue?
    A) Only carbon steel
    B) Only carbon steel, and high nickel alloys
    C) All materials
    D) Only carbon steel and chromes
    C) All materials
    (this multiple choice question has been scrambled)
  3. Fatigue will not occur in carbon steel if stresses are below the:
    endurance limit
  4. Which condition contributes to Mechanical Fatigue.
    A) Temperature:Low temps/High temps/ Not a factor.
    B)Steel properties:Dirty steels/Clean steel/Not a factor
    C)Grain structure:Fine-grain/Coarse-grain/Not a factor
    D)Surface Condition:Notches/Smooth surface/Not a factor
    E)Process ph:High ph/Low ph/Not a factor
    • Temperature: not a factor
    • Steel properties: Dirty steel
    • Grain structure: Coarse-grain
    • Surface condition: Notches
    • Process ph: Not a factor
  5. The endurance limit is usually about:
    40-50 % of a material's ultimate tensile strength
  6. Which material does not have an endurance limit
    Stainless steel
  7. Mechanical Fatigue can cause cracks that initiate from the surface and often form a :
    clam shell appearance
  8. The best defense against Mechanical Fatigue is a:
    Good design that minimizes stress concentrations
  9. Inspecting for high-cycle Fatigue can be difficult since:
    once the crack begins, only a few cycles are needed for the crack to lead to failure
