Homework Help: Wheelbarrow Force Analysis

  1. Oct 29, 2009 #1
    1. The problem statement, all variables and given/known data

    Where is the best place to arrange most of the logs in a wheelbarrow so that it minimizes the amount of force on the backbone of the person transporting the load?

    2. Relevant equations

    Moment = Fd or r x F

    E.O.E:
    Sum of Fx = 0, Sum of Fy = 0, Sum of Fz = 0.
    Sum of Mx = 0, Sum of My = 0, Sum of Mz = 0.

    3. The attempt at a solution

    This is basically just a force analysis problem with no weight or dimensions given. Any help would be appreciated.

    Hi camino! :wink:

    The force on the backbone is just the extra force on the feet.

    So what will that be related to? :smile:
