Homework Help: Grr, another max load question

  1. Nov 5, 2006 #1
    What is the maximum load that could be suspended from a copper wire of length 1.5 m and radius 1.1 mm without breaking the wire? Copper has an elastic limit of 3 × 108 Pa and a tensile strength of 4.2 × 10^8 Pa

    F/A<Elastic Limit

    = m(9.81) / 3.8013 = 3x10^8Pa
    9.81m= 114 098 123
    m= 116 248 535 N ???

    Seems like an aweful lot of load, what did i do wrong on this one?
