This Demonstration solves a system of two masses hanging from two pulleys, with one of them swinging and the other moving vertically, a system known as a "swinging Atwood's machine." The variables of the system are the angle
θ
and
r
, the length of the string of the swinging mass, both depending on the time
t
. Friction is neglected.
