Fulcrum Puzzles

Each square below contains either a fulcrum, or a weight from 0-3. Each group of squares surrounded by black lines is a balance containing one fulcrum where it would balance, with equal torque on both sides. The fulcrum will not be at the end of a balance. Each number outside the grid indicates the total weight in that row or column, counting fulcrums as 0. Each puzzle below has a unique solution. All puzzles copyright Erich Friedman, 2010.
