- Abstract:
- Part 2: Using a single two-wire pendulum, investigated whether a permanent “set” caused by an enforced pitch is observed, whether the effect was proportional, and whether an increase in “d” distance would decrease the permanent “set” for a given input displacement. Finer resolution repeat of the work in T080033, including with wires brazed into clamps. Effect still visible at smallest observable tilts.
