Elementary lessons in the physics Elementary lessons in the physics of agriculture elementarylesson01king Year: 1894 13 an equal volume of water be immersed in water it will be lifted by a force equal to the difference between the weight of the block and that of an equal volume of water, as shown in Fig. 1. a s c d e Fig. 1. Regarding the water of the vessel divided into cubes exactly equal in volume to the block of wood, and the block just half as heavy as an equal volume of water, then the weight of column A equals 2+2 + 1=5, while the weight of column B is 2 + 2 + 2=6. Now, as column B exerts a pressure upward on the column A equal to its own weight, the block in column A must be pushed upward by a force equal to the difference in the weight of the A comparison of columns B and C will show that it makes no difference where the block is placed in the liquid, the force which tends to lift it to the surface is always the same. If the attraction of the earth were just twice as strong as it is then the cubes of water and the block in column A would weigh 4 + 4 + 2=10, and the cubes of water in column B would weigh 4 + 4 + 4=12, and the lifting force on the block would be 12-10=2, or just twice what it now is; so if the force of gravity were made one hundred times what it now is, the lifting force act-
