Objective: Build an apparatus that allows you to rotate a cylinder of liquid about its vertical axis, measure the rotation speed, and measure the interface. Compare to solution of Euler-Langrange equation. (Donnelly is the name of a famous physicist who carried out many versions of this experiment with superfluid helium.)
Progress:
Fall 2001 (Jeffery Elms) Very well written and clear report. Built apparatus with a CD motor. Circuits available in report. Visual comparison of photographed interface and calculated interface could be improved.
Fall 2002 (Joshua Cuneo, Narendhra Seshadri, Jennifer Lee, and Justin Melvin)
