The Cycloid Bench
Interactions
- Click the gate: the four balls are released together and race to the finish; the first trips the flag and tally marks note the order
- Drag the finish peg: all four tracks are re-cut to pass through the new point, and the race is run again
- Lift a ball in either bowl, or pull either pendulum bob aside, and let go: pegs catch the others, its twin follows to the same height, and all are released together
