| 1G30.00 | Complex Systems | | |
| 1G30.11 | Poggendorff's experiment | AJP 38(4),541 | The reaction on an Atwood's pulley hanging from a scale is twice the harmonic mean of the suspended weights. |
| 1G30.11 | tension in Atwood's machine | 8-1.4 | Hang an Atwood's machine from a spring scale and take readings in both static and dynamic cases. |
| 1G30.12 | double Atwood's machine problem | M-112 | The mass on one side of the Atwood's machine is replaced with another Atwood's machine. |
| 1G30.20 | mass on spring, on balance | PIRA 1000 | |
| 1G30.20 | mass on spring, on balance | 1G30.20 | A mass on a spring oscillates on one side of a tared balance. |
| 1G30.20 | mass on a spring, on balance | M-114 | A large ball on a stretched spring is tared on a platform balance. The string is burned and the motion observed. |
| 1G30.20 | acceleration on a balance | M-8c | Burn the string extending a mass on a spring on a tared platform balance. |
| 1G30.25 | weigh a yo-yo | 8-3.14 | A yo-yo is hung from one side of a balanced critically damped platform scale. |
| 1G30.30 | hourglass on a balance | PIRA 1000 | |
| 1G30.30 | hourglass on a balance | 1G30.30 | An hourglass runs down on a tared, critically damped balance. |
| 1G30.30 | acceleration of center of mass | Mp-19 | A very large hourglass is placed on a critically damped balance. The deflection is noted as the sand starts, continues, and stops falling. |
| 1G30.30 | acceleration of center of mass | 9-4.10 | An hourglass full of lead shot is tared on a critically damped platform balance. The resultant force is observed as the lead shot starts, continues, and stops falling. |
| 1G30.30 | hourglass on a balance | M-116 | An hourglass on one side of a equal arm balance. |
| 1G30.31 | acceleration of center of mass | 9-4.13 | An apparatus to show transient and steady state conditions in the hourglass problem. |
| 1G30.32 | the hourglass problem | AJP 53(8),787 | Careful analysis and demonstration shows that the center of mass is actually accelerating upwards during most of the process. |
| 1G30.33 | acceleration of center of mass | M-8d | A funnel full of water is placed on a tared platform balance and the water is then released and runs into a beaker. |
| 1G30.34 | reaction balance | M-115 | One mass on an equal arm balance is supported by pulleys at the end and fulcrum. The balance is in equilibrium if the string holding the mass is held fast or pulled in uniform motion. Look it up. |
| 1G30.35 | acceleration of center of mass | 9-4.12 | A ball is dropped in a tall cylinder filled with oil while the entire assembly is on a balance. A hollow iron ball may be released from an electromagnet on the bottom and float to the top. |
