- Discussion:
    - maximum load that metal can withstand in a single application without breaking;
    - w/ application of a load, maximum stress will be achieved;
         - this is ultimate tensile strength, & is maximum stress material can sustain before fracturing;
         - note that on the stress-strain curve, the ultimate tensile strength will be seen as the peak on the graph, which is
                  subsequently followed by increasing strain w/ decreased stress (frx processs);
    - when the ultimate tensile strength is exceeded, the metal will break;
    - from highest to lowest ultimate strength:
    - wrought cobalt chrome, titanium, stainless steel (wrought), cobalt (cast), cortical bone
