Homework Help: Fracture energy equation?

  1. Apr 7, 2010 #1
    1. The problem statement, all variables and given/known data
    i have been told i can use the equation potential energy/cross sectional area to work out fracture energy of ice after dropping weights on it till it breaks. is this true?

    2. Relevant equations
    fracture energy = potential energy/cross sectional area

    3. The attempt at a solution
    as above

    It seems rational: as the units you would be given are [tex]Jm^{-2}[/tex] which would imply the energy per unit area.
