Homework Help: Find Curve for max work of a Force field

  1. Jun 14, 2010 #1
    1. The problem statement, all variables and given/known data

    We have the force field F= (-4y+yx^2)i - (xy^2)j. Find the simple closed curve in which the work produced by the Force field is maximum


    2. Relevant equations
    vector calculus( curved intergrals second type, green stoke's gauss theorems...)
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    What's the definition of work (it involves an integral)? How would you go about maximizing some known function g(x,y)? Apply that to the definition of work, using the fundamental theorem of calculus.
