A 2×12 board of airdried Southern Yellow Pine (~12% moisture) is about 2.18 kg per linear foot. A physicist and his wife carry a 16-foot length of Southern Yellow Pine lumber, the physicist gallantly carries the board from one end while his wife carries the board 4 feet from the other end. How much weight is each spouse carrying? This is an equilibrium problem. Assume the board is perfectly uniform.
