SpletMeniscus forces. The interaction between lubricant on the disk and a near contact slider has been a critical topic. The lubricant meniscus force has also been considered as the main cause of the hysteresis. One noticeable phenomenon associated with the lubricant is the ‘washboard effect’. SpletBoth the normal and horizontal components of the meniscus force could contribute to the friction. Liquids that are wet or have a small contact angle on surfaces will spontaneously condense into cracks, pores, and small gaps surrounding …

"SpletThe menisci are two rubbery disks that help cushion the knee joint. Description The meniscus can tear from acute trauma or as the result of degenerative changes that happen over time. Tears are noted by how they look, as well as where the tear occurs in the meniscus. Common tears include bucket handle, flap, and radial. " - The meniscus effect

Splet06. jun. 2024 · What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass. Why a meniscus occurs Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface … SpletMenisci are a manifestation of capillary action, by which either surface adhesion pulls a liquid up to form a concave meniscus, or internal cohesion pulls the liquid down to form a convex meniscus. This phenomenon is …
