| 3B39.10 | water wave model | PIRA 1000 | |
| 3B39.10 | water wave model | 3B39.10 | A row of short rods mounted on the side of a box rotate at the same rate with equal phase shift between successive rods. The combined motion simulates a traveling water wave. |
| 3B39.10 | water wave model showing phase vel. | Sa-4 | Balls that rotate vertically on the end of rods hooked to horizontal shafts and are coupled together with a regular phase difference. |
| 3B39.12 | water wave model | 18-8.15 | A set of 28 rotating arms driven in circular motion with constant successive phase difference. Pictures. Construction details in appendix, p.644. |
| 3B39.14 | rotating phasors | 18-8.12 | Synchronous motors drive a set of balls in a circle with phase relationship such that the balls describe a sine wave. |
| 3B39.20 | dominoes | PIRA 1000 | |
| 3B39.30 | multiple wave types | 18-8.11 | A machine demonstrates transverse, longitudinal, and water wave motion. Picture. Construction details in Appendix, p.636. |
| 3B39.52 | seismograph | S-2j | The output from seismographs are shown on an oscilloscope. |
