Dependence of knot probability on physical parameters
| Condition | Box width |
||
|---|---|---|---|
| 0.1 m | 0.15 m | 0.3 m | |
| 3-m length of #4 string, tumbled at one revolution per second for 10 sec | 26% | 50% | 55% |
| Slower tumbling (0.33 revolutions per second) | 29% | 52% | 57% |
| Faster tumbling (three revolutions per second) | 8% | 17% | 20% |
| Longer tumbling time (30 sec) | 30% | 74% | 63% |
| More flexible string, 3 m | — | 65% | — |
| More flexible string, 4.6 m | — | 85% | — |
| Stiffer string, 3 m | — | 20% | — |
The physical properties of the strings are given in Materials and Methods. The percentages were determined from 200 trials.
