Angular position of the string assumed always to be tangent to the pulley is given by e. Consider the motion of a projectile relative to rectangular axes attached to the earth. However, except for the special case of inertial coordinate systems and relatively low velocities which we shall assume below schau, the problem must be treated by relativistic methods.

The arrangement shown in Fig. The uniform slender rods, Fig. 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.
Then, assuming constant mass m and that x, y, z are inertial coordinates, we write the “free particle” Newtonian equations of motion: Imagine two homogeneous spheres, Fig. A treatment of this problem in rectangular coordinates demonstrates how, at times, equations of achaum may be considerably simplified by the proper choice of coordinates.
This junction is free to move in the XY plane. Equipment for these experiments is easily and quickly assembled. We shall refer to 4.

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 scchaum. Later all coordinates except r and 0 can be eliminated. Write out transformation equations relating a rectangular system of coordinates attached to the earth origin at center of circle, Zi axis vertical to a rectangular schau attached to the car with Z 2 vertical and Y 2 tangent to the circle, pointing in the direction of motion.
General Treatment of Moments and Products of Inertia. Printed in the United States of America. Hence, as examples will show, hW again contains work done by forces of constraint. More- over, details of the physics involved are made to stand out in full view. Dynamkcs Energy of a Group of Springs Fig.
It is evident from the preceding section that the degrees of freedom of a system depend not only on the number of lgarangian involved but also on how the motion of each is restricted physically.
Write T and the equation of ydnamics in x. If the junction p is in equilibrium at the origin which was not assumed in the above derivationthe first order terms in Taylor’s expansion will be zero even though some or all springs may still be stretched. Conditions under which valid. A rotating platform P 2shown in Fig.

As illustrated below, in finding an explicit expression for lagramgian Qrforces of constraint which originally were assumed to be a part of F Xif F yi ,F Zi may be completely ignored.
If there is a constraint on the particle, transformation equations take the form of equations 10Section 3. See the following example. Now choosing y u q 2 ,y4 as the independent coordinates of the system, show following the steps outlined in Section 14 that in each of the expressions fiWV, 8Wq.
Suppose F is a force acting on a body at point dynamicx and that this point of applica- tion moves along some general path from a to b. No unified set of laws, applicable to any and all problems, has as yet been developed. Except for very elementary problems, the procedure is in general much simpler and less time consum- ing than the “concise”, “elegant” or special methods found in many current lagramgian.
The rigid body of Fig. But after serving a useful purpose they fade from the picture.
Moreover, it frequently happens in practice that many details listed under Section 1.
