The barrel is filled to the top with water. Determine the distance s that the top hoop should be placed from the bottom hoop so that the tensile force in each hoop is the same. Also, what is the force in each hoop? The barrel has an inner diameter of 4ft. Neglect its wall thickness. Assume that only the hoops resist the water pressure. Note: Water develops pressure in the barrel according to Pascal's Law, p=62.4 lb/ft^2, where z is the depth from the surface of the water in feet.
