Here We Go Again

Speaking of the bathroom scale!
I recently saw a trick for determining the tongue weight of a trailer using one. The trick was to take a stout enough board and a brick or two. Set one end of the board on the brick and then set the tongue of the trailer 1 ft. to the side of it on the board. Then place the scale 3 or 4 ft. from the brick depending on the mecanical advantage you need to reduce the tongue weight so that the resulting reading is within the range of the scale. Then multiple the reading on the scale by the ratio of the number of feet from the brick to the scale. ex. scale 4 ft. from brick with reading of 100 lb. would work out to 400 lb. tongue weight. Not surprising, but ingenius!
