**theorems**in the theory of equations are to be found in the same work. - At the same time, it delights the pure theorist by the simplicity of the logic with which the fundamental
**theorems**may be established, and by the elegance of its mathematical operations, insomuch that hydrostatics may be considered as the Euclidean pure geometry of mechanical science. - So far these

**theorems**, which hold for the motion of a single rigid body, are true generally for a flexible system, such as considered here for a liquid, with one or more rigid bodies swimming in it; and they express the statement that the work done by an impulse is the product of the impulse and the arithmetic mean of the initial and final velocity; so that the kinetic energy is the work done by the impulse in starting the motion from rest. - If, however, we defined the strength of the source by the statement that the strength divided 1 The beginner is often puzzled by the constant appearance of the factor 47r in electrical
**theorems**. It arises from the manner in which the unit quantity of electricity is defined. - Let us apply these
**theorems**to a portion of a tube of electric force. - Mensuration involves the use of geometrical
