Schematic diagram of the LSTV and its measurement system; for concise presentation, only the horizontal component of the surface tension is included in the diagram.
(a)–(e) Selected frames from a movie on the LSTV in free vibration; direction of motion is to the left; (f) a drop of de-ionized water was dropped onto the top surface of the lower plate; (g) the upper plate was placed on the water drop; (h) plot of the shear vs [the measured values (line with square dots) and the fitted values (line without dots)].

(a) Experimental curve and the simulation curve of the free vibration of the LSTV (inset: mechanical equivalence model of the LSTV); (b) experiment data (square and circle dots) and the simulation curves (continuous lines) of the vibration frequency or the period vs the water film thickness.
Experimental curve of the forced vibration of the LSTV: (a) relationship of time vs velocity; and (b) relationship of frequency vs amplitude; water film thickness is 0.35 mm.
