Edinburgh New Philosophical Journal. 50 Mr Russell on the Fallacies of the thetical case of uniform reciprocating motion in the piston; so that the piston, when elevated and depressed by the steam, draws the crank down with it from A to B and C, and raises it up with it from C to D and A. Let the orbit of the crank be di- vided into twenty equal parts, the first ten numerals being placed on the descending side, and the other ten on the ascend- ing side of the circle. Let the length of the stroke of the pis- ton, which is equal to the diameter of the circle, be divided into ten parts, shewing the place of the piston at every instant of its stroke, contemporaneous with the points of the crank in its orbit; the first ten numerals corresponding both in the circle and the cylinder with corresponding points of reciproca- tion and of revolution. Now, at each of these points, let us examine into the relation which exists between the pressure of the steam on the piston And the quantity of the effect produced in revolving the crank, and that part of the pressure of the steam which produces no motion, and which is therefore erroneously said to be lost. The jjressure of the steam acting obliquely on the crank produces two effects;—pressure towai'ds the centre through the crank, and motion in the direction of the circle tangentically.
