Examples:
A hopper scale is placed on one load cell and two pivots. If load cells are arranged
rotation-symmetrically, and the two pivots around a round-shaped hopper with mid
center of gravity ( load carrier to 3 x 120°) the load is distributed to 1/3 each:

With a rectanglular hopper or a round-shaped hopper in a symmetrical weighing
frame, the result is different (even if the latter is square and totally symmetric):
