    1.) (A) DEFECTS
    Metals yield at a stress much lower than those calculated on the basis of their bond strength alone. This is explained by the presence of defects. Identify the principal defects responsible for this observation.

    a.) Grain Boundaries
    b.) Interstitial Metal Atoms
    c.) Vacancies
    d.) Dislocations
