64. Extended cyclical variations in tensions will cause an anchor chain to break due to __________.
Fatigue is the correct answer; repeated cyclic loading causes microscopic cracks to form and grow, leading to failure even if individual loads are below the ultimate strength. Cyclic tension induces fatigue, unlike abrasion (surface wear), corrosion (chemical attack), or distortion (deformation from overload).
