Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion.It is highly interdisciplinary, drawing on many academic fields, including physics, chemistry, materials science, mathematics, biology and engineering. [1]
Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints.With its egg white–like consistency, [1] the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. [2]
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
Dispersed nanoparticles have been shown to reduce boundary friction, [6] but they have not yet found widespread employment in industrial applications. [1] Reduction of frictional losses and through more efficient lubrication is a key target in order to reduce carbon dioxide emissions. [7]
Asbestos, a known human carcinogen, can be injurious to consumers if found in talc-containing cosmetic products as there is no established "safe level" threshold for exposure to the substance. If ...
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology.
A Minnesota couple has reportedly been sentenced to four years after they locked their children in cages for "their safety." Benjamin and Christina Cotton from Red Wing, were sentenced by a ...
