A liquid bridge is a volume of liquid held between two or more
solid supports. In the case of small disk supports with a sharp
edge, the contact line between the bridge and the support disk will
be anchored along the edge of the disk. For these cases the solid
presents a geometrical singularity and the contact angle is
indeterminate within a given range. This dissertation presents
research conducted on liquid bridges with anchored contact lines.
The three major topics covered are: determining the role of support
geometry on static equilibria, liquid bridge dynamical behavior,
and forces exerted by a liquid bridge on a support structure. The
work was primarily experimental and conducted in a "Plateau tank"
that allowed for the simulation of equivalent low-gravity
conditions. The main thrust of the experimental work involved the
use of a high resolution optical measurement system for imaging the
dynamic zone shape, measurement of the static and dynamic contact
angles and non-invasive analysis of excited surface modes. The
liquid bridge was manipulated by computer controlled linear
actuators which allowed precise control over the physical
characteristics of the bridge. Experiments have been carried out to
locate a bifurcation point along the maximum volume axisymmetric
stability margin. Below the critical slenderness the bifurcation
from an axisymmetric to a stable nonaxisymmetric configuration is
supercritical. However, above this critical slenderness, the
bifurcation is subcritical. A series of experiments analyzed the
effect on axisymmetric bridge stability by using support disks of
different radii, The shape behavior as transition points were
approached, as well as the limiting case of a vanishing support
radius was investigated. Experiments were performed to determine
the resonant frequencies of axisymmetric bridges subject to lateral
vibrations. Anomolous results led to a series of experiments to
characterize nonlinearities present in the dynamic bridge shape.
