Página 9 - In considering the first theory, that of resistance to overturning, the easiest method of examining the question will be to take a simple example of a vertical rectangular wall, and ascertain what power it exercises to resist the pressure of water. The pressure of water upon any plane surface immersed is known to be equal to the area of that surface, multiplied by the depth of its centre of gravity below the level of the water and by the weight of a unit of water. Generally speaking, the unit adopted...
