Rotational Dynamics

Logo for Rotational Dynamics
An Atwood machine for demonstrating the relationship between an unbalanced torque and rotational acceleration. The rope connecting each mass is wrapped around a pulley at different radii, which are user-defined. Extensive explanatory text included.

In reviewing John Walkup's assignment that uses this applet, I obviously have
become familiar with the applet. It has some nice features, but a few defects.
First, although it is possible to set the radius of the inner pulley, nowhere
that I could find is a statement of the size of the outer radius. (It may be
buried in the extensive discussion of the system, which is in Spanish.) Second,
the value of the unknown moment of inertia of the pulley (obtained via the
"Resultado" button) has no units, but in fact is in kg-m^2. This could be very
confusing, because the given quantities are expressed in terms of centimeters
and grams.

this is a good site, though the language difference complicates a rather simple

There are many similar applets, but this one has the benefit of very nice graphics and an extensive discussion, albeit in Spanish.
