[5] [6] Contact between raised solid features, or asperities, can also occur, leading to a mixed-lubrication or boundary lubrication regime. Boundary lubrication is defined as the regime in which the load is carried by the surface asperities (high points) rather than by the lubricant. [ 7 ]
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.
Energetically modified cement – Class of cements, mechanically processed to transform reactivity; Friction – Force resisting sliding motion; Friction drive – Mechanical power transmission by friction between components; Lubrication – The presence of a material to reduce friction between two surfaces.
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]
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.
"Alcohol has a half-life of four to five hours, so if you drink at happy hour at, say, 6 p.m., that alcohol will stick with you until around 11 p.m., which can be way too late to fall asleep ...
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]
