Mass distribution of a semi-infinite stick

  1. Jun 7, 2015 #1
    1. The problem statement, all variables and given/known data
    Given a semi-infinite stick (that is, one that goes off to infinity in one direction), determine how its density should depend on position so that it has the following property: If the stick is cut at an arbitrary location, the remaining semi-infinite piece will balance on a support that is located a distance l from the end.

    2. Relevant equations
    T = r x F

    3. The attempt at a solution
    In the linked solution, I understand the setup, but I do not understand how to find the derivative of the integral with respect to x0. Can someone give me a more detailed explanation of this step?
