Hence in “classical dynamics” the greatest concerns are with A and B, It is evident from the above conditions that there exist three more-or-less well defined fields of dynamics: In general some or all of the forces may vary with time. Let 6 represent any general position algrangian the system. This is determined by inspection. The light rigid rod supporting the “particle” of mass m h shown in Fig. For simplicity consider a particle of mass m constrained to move in contact with a rough surface which is itself in motion.
Given lagrangixn expression for s in one system of coordinates, we can express it in another by means of transformation equations or reduced transformation equa- tions relating the two. As a simple example consider the double lagdangian of Fig. The string to which m is attached is wrapped around and fastened to the disk.

On the contrary, as will soon be evident, they are employed perhaps just as frequently as inertial. X and Y axes are attached to the face of the disk with origin at its center. It is designed for use either as a textbook for a formal course or as a supplement to all current texts.

When any one of these sets is given, the configuration of the system is said to be determined. This technique of determining Lagrsngian is simple and frequently very convenient.

Show that the work done by the forces of Problem 5. The use of qi, 2. The “basic laws” of dynamics are merely statements of a wide range of experience. Inertial forces are never included.
But since we already know them, why bother to find V and determine them again from F x. Now the reader can easily show that for a variation of either s 4 or q u holding t fixed, the work done by the tensions adds up to zero; this is also in accord with lagrzngian last part of statement c.

Note that SWtotai has the form of equation To see what your friends thought of this book, please sign up. It should be clearly understood that frictional forces are not included in this class. While the truth of this statement is easily demonstrated llagrangian simple examples Section 2.
The particle of mass m f shown in Fig. It is important to note that when coordinates are changed the form of the equations of motion may change greatly. Theoretical treatments as well as the solution of applied problems in the field of analytical dynamics involve, in addition to the important matters discussed in Chapter 1, an immediate consideration of generalized coordinates, transformation equations, degrees of freedom, degrees of constraint, equations of constraint, velocity and kinetic energy as expressed in generalized coordinates, general expressions for acceleration, and the mean- ing and use of virtual displacements and virtual work.
Di and D 2 shown in Fig. Neglect masses of pulleys. It is especially useful, for example, in the treatment of electro- mechanical sytems. A treatment of such matters is out of place here, but the serious student will profit from the discussions of Bridgman and others on this subject 1. Note that V is here defined as the work from the general to the reference con- figuration and not the other way around.
We shall refer to this relation as “D’Alembert’s equation”.
