The graphs below show piston locations versus time for the thermalized experiments.
(The time coordinate in the preceding movies goes up to 350.)
Graphs 2, 4, and 5 are all for the case where the piston has mass 1.
Other Graphs have piston mass 10.
Graphs 5 and 10 are controls where the driver
does not touch the piston.
Graphs 12, 14, and 16 are the twodriver cases.
Graphs 4, 9, and 14 use the expanding funnel shape; 16 has a triangular shape, so volume goes as x^2.
The graphs give the impression, as expected, that
(1) lots more work is extracted when
there are two drivers; (2)
slightly more work is extracted when
we have the funnel shape.
