Think of the spine as a fishing rod supported by muscular guy wires.
Much the same thing happens for a bendable rod supported by surface tension, Vella says.
This paper describes the experimental results of grid-to-rod fretting carried out to examine the effects of flow rate and rod support conditions.
The lateral support conditions, which should restrain lateral translation and twisting rotation but allow flexural rotations about the strong and weak axes of the cross-section, were provided using a ball caster and circular rod support.
The grid-to-rod fretting wear-induced fuel rod failure observed in PWRs may be caused by excessive fluid-induced vibration and inadequate fuel rod support by the spacer grid spring.
The structural components such as fuel rod supporting structure, top and bottom end pieces and guide tubes could be designed without a drastic change of those of the conventional fuel.
In order to simulate in-reactor grid-to-rod fretting wear behaviors, the grid-to-rod fuel rod supporting conditions as a function of time were predicted by taking into account cladding creep rate, initial spacer grid spring deflection, spacer grid spring force relaxation, etc.
Effects of platinum particle size on the hydrogen electrode reaction have been examined in an aqueous solution of sulfuric acid by use of a Pt/GC model catalyst electrode which was prepared by vacuum evaporation of platinum onto a flat surface of a glassy carbon rod support.
As a team, a group of adolescents raced to guide a long metal rod – supported by just their extended index fingers – down to the ground without dropping it.
A bronze ring, suspended from the ceiling by bronze rods, supports an urn-shaped lamp mechanism and four glass lanterns from which cut-glass tinklers dangle.
