 |
Working Model, from Knowledge Revolution, Inc., is a software
package designed to provide analysis, simulation, and animation tools for
modeling physical systems. |
|

The
Student Edition of Working Model is published and distributed by Addison Wesley Longman, who can be contacted
by phone at (800) 822-6339. |

| Examples |
|
The following are Working Model (.wm) files. You can save these files to
disk and open them in Working Model to view the simulations. If, when
opened in Working Model, you have problems (such as wrong format),
the files can be downloaded via ftp from quinn.mechanical.uakron.edu. |

Double pendulum [11k]:
this simple system is one of the canonical ``chaotic'' toys. In particular
it exhibits sensitive dependence on initial conditions. Small initial
variations in the position and velocity of the links lead to dramaticallly
different results. |
|
|
Magnetic spindle [15k]:
as modeled in class, we find large amplitude oscillations as the rotational
speed of the spindle approaches the natural frequency of oscillation in the
verticle direction. |
|
|
Mass center [9k]:
the mass center of a system of interconnected balls behaves like a single
particle. |
|
|
Spring-mass-damper [10k]:
this model, which leads to a constant coefficient linear differential
equation, is the basis for much of linear vibration theory. |
|
|
Kinematic inversion [33k]:
Although the relative motion between the links is identical, the
absolute motion with respect to the ground is ver different. |
