The Method of Mechanical Theorems convenient to use a little bit of coordinate geometry. If a sphere of radius 1 is placed with its center at "x" = 1, the vertical cross sectional radius formula_2 at any "x" between 0 and 2 is given by the following formula: The mass of this cross section, for purposes of balancing on a lever, is proportional to the area: Archimedes then considered rotating the triangular region between "y" = 0 and "y" = "x" and "x" = "2" on the "x"-"y" plane around the "x"-axis, to form a cone. The cross section of this cone is a circle
Power-to-X Power-to-X Power-to-X (also P2X and P2Y) has two meanings. First, power-to-X refers to a number of electricity conversion, energy storage, and reconversion pathways that utilize surplus electric power, typically during periods where fluctuating renewable energy generation exceeds load. Second, power-to-X refers to conversion technologies that allow for the decoupling of power from the electricity sector for use in other sectors (such as transport or chemicals), possibly using power that has been provided by additional investments in generation. The term power-to-x is widely used in Germany and may have originated there. The X in the terminology can refer to one of
