Question

A sealed barrel of oil (weighing 48 pounds per cubic foot) is floating in seawater (weighing 64 pounds per cubic foot), as shown. (The barrel is not completely full of oil. With the barrel lying on its side, the top 0.2 foot of the barrel is empty.) Compare the fluid forces against one end of the barrel from the inside and from the outside. (Assume the radius of the barrel is 1 foot and, with the barrel lying on its side, the top 0.6 foot of the barrel is above the water.)
