In like manner P 2 rotates with constant speed w 2 relative to Pi. Motion is confined to the XY plane. A motor is connected to three pulleys in the manner shown in Fig. Examples should make clear this statement and how the desired results are obtained.

Therefore forces of constraint may be disregarded. A type of problem sometimes encountered in practice may be illustrated by the following. What are the components of the reactive force in the directions of increasing B and 0? The particle is free to move about on the plane under the action of the spring. If the masses are free to move in a plane, then V will, of course, involve the x and y coordinates of each mass.

A bead of mass m is free to move on a smooth circular wire which is rotating with constant angular velocity w about a lagrahgian axis perpendicular to the face of the loop and passing through its periphery. Would the degrees of freedom be the same without the springs, that is, with no connection between masses?


Equipment for these experiments is easily and quickly assembled. Show that when coordinates y, yi and lagtangian 2 are echaum to represent the configuration of the system in Fig.

One must be able to recognise inertial and non-inertial frames by inspection. However, since numerous problems of this type occur in practice, it is important that the derivation and application of Lagrange’s equations to such systems be given careful consideration.

We always begin by writing T in inertial coordinates. A system moving with constant linear acceleration.

The electric motor, shown in Fig, above, is free to slide to any position on a smooth horizontal plane. The differential equations of motion for any specific problem are, of course, obtained by performing the operations indicated in 3.

A solid uniform disk of mass M and radius R has attached to its face a small mass m at a distance r from its center. Mac rated it it was amazing May 01, The pendulum bob of mass in, shown in Fig. Hence the dynaimcs of Section 2.

Consider a system of p particles on which conservative forces Fx, F 2. Also, of course, relations 5. But after serving a useful purpose they fade from the picture.

Any one of several formulations of the fundamental laws of dynamics may be taken as the basis for the derivation of the Lagrangian equations.

Gear C is free to rotate on the crank handle. Two uniform bars each free schau, swing in a verti- cal plane about horizon- tal rod P.

They still can be used as a “frame of reference” though for most problems not a very desirable one. Note that SWtotai has the form of equation This means, of course, that differential equations formerly regarded as “hopeless” are presently of great concern to scientists and engineers. Two principal types of problems and their general treatment. We shall assume that the student is familiar with the use of the above relation in simple problems and postpone a lavrangian treatment of moments of inertia and kinetic energy of a rigid body until Chapters 7 and 8.


Springs, having torsional constants ki and k 2are fastened to S 2 and S 4 as indicated.

Many theoretical developments depend on the use of transformation equations. This displacement is along the rod: Path of w 2 as seen from mi. However, we shall not be concerned with rynamics problems in this text. As dnyamics means of introducing dgnamics illustrating the basic principles on which this chapter is founded, consider the following examples. Formal vector methods are not stressed; they are mentioned in only a few sections. Anant marked it as to-read Oct 17, In the system of gear wheels shown in Fig.

The surprising importance of 2. As regarded as a vector. Hence in the discussion of techniques and examples which follow, these forces are disregarded. In other words, generalized forces are determined by imagining the frame of reference and constraints at rest and then proceeding exactly as explained in Section 3.
