This can then, if so desired, be written in terms of any other coordinates inertial, non-inertial, or mixed by means of proper transformation equations.

This simple example does not demonstrate the power of the Lagrangian method. A smooth tube containing masses mi and m 2 connected with springs is mounted on a rotating table at an angle a. Bismarck marked it as to-read Oct 29, Again, both expressions are the same except for a constant term in the second. D 2 can move vertically. Disk Di, shown in Fig. The problems weren’t helpful as I dynamcis to review the material preparing for our Master’s final.

Regarding the above displacements as arbitrary not in conformity with schaummit is clear that work done by the forces of constraints tensions will not in general be zero. Forces of constraint, for smooth holonomic constraints, are automatically eliminated and do not appear in the Lagrangian equations. For carefully determined values of k and m, experimental and computed values of the period check closely.


The number of independent coordinates not including time required to specify completely the position of each and every particle or component part of the system.

Wells McGraw-Hill authors represent the leading experts in their fields and are dedicated to improving the lives, careers, and interests of readers worldwide show more.

The virtual displacements Bx, By, Bz, will, for reasons stated below, be determined from A system of three particles. From this point on, equations 3. See also Example 4. Cognizance of this should become automatic in our thinking because, basically, the treatment of every problem begins with the consideration of an inertial frame. Consider a system of p particles having masses mi, m 2. If there is a constraint on the particle, transformation equations take the form of equations 10Section 3.

The equations of motion follow at once. That is, Bs could be in a direction such that the lagranggian with which m is in contact is slightly “distorted”.

Other books in this series. Substituting this into 5. If support A B is moving, two coordinates and t are required; however, it is still regarded as having two degrees of freedom. But it is possible to write a “vector potential” function leading to a new form of L such that 5. Very frequently the equations are non- linear.

Repeat this for the systems for which certain specified motions are indicated. Let us compute the work done by the spring for a displacement of the particle from some reference point x Q ,y Q to a general point x,y.

It will be assumed that some or all constraints may be moving and that any or all of the generalized co- ordinates are non-inertial.

Pi is driven by a motor at a constant speed Wl. Pendulum lagrangiah a sliding support The pendulum of Fig. Through the use of these equations, “superfluous coordinates” can be eliminated from transformation equations, kinetic energy, potential energy and other quantities.

But a word of warning. Allowing qi to vary and plotting relations 1 and likewise 2 for various constant values of q 2qa, t, gi-lines of mi straight lines on the cone and gi-lines of m 2 radial lines on P are obtained. For many dissipative forces the “power function” method offers advantages; see Chapter 6.
