Equation of motion/ static equilibrium

  1. Sep 12, 2009 #1
    1. The problem statement, all variables and given/known data

    I have notes on mechanics, and under the titile equation of motion/ static equilibrium there is the equation:


    2. Relevant equations

    3. The attempt at a solution
    I know that rho is the density, t is time, sigma is stress but what does the 'u' and 'f' represent?

    thank you
