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!

The force on the backbone is just the extra force on the feet.
So what will that be related to?
