So I had a guy show me a very cool method (which I forgot) to find the lbs/inch of a load. The reason is to find out how far to move the item on the trailer so it is balanced weight wise. I know the weight of the axle groups front and rear on the trailer and I know the distance from the kingpin to the center of the rear axle. I just can't for the life of me find the formula to find the lbs/in. I haul large machines and knowing the formula would save me massive amounts of time.
