friction

A soft tissue massage technique, which entails the use of small circular pressure strokes from the fingertips, thumb pads and palms, with the intent of mobilising stiff joints and enhancing the circulation of blood to tendons and ligaments.

fric·tion

(frik'shŭn)
1. The act of rubbing the surface of an object against that of another; especially rubbing the limbs of the body to aid the circulation.
2. The force required for relative motion of two bodies that are in contact.
3. A group of movements in massage intended to move superficial layers over deeper structures, to reach deeper tissues, or to create heat. Includes static, cross-fiber, with-fiber, and circular frictions.

The absolute value of the coefficient of friction did not indicate significant differences between these two lubricants.
The knowledge of the estimated brake linings coefficient of friction allows calculating a brake pressure control signal.
"The new composite [plastic] balls' coefficient of friction outperformed the leather balls' coefficient of friction in both wet and dry conditions," says mechanical engineer Ron Laliberty, Spalding's director of new-product development.
shows that the resonant amplitude of blade is changed with increase of normal load at different coefficient of friction. The position of curves changed with change of coefficient of friction and optimum normal load is shifted.
Hence, log-log coefficient of friction, thru-rod tension, thru-rod hole size, and connection type are important.
The smooth core has the lowest coefficient of friction of any solid material and is inert, imparting neither taste nor odor to substances flowing through it.
Although a smooth base film is necessary to achieve low noise performance, the smoother the base film, the higher the coefficient of friction. To maximize the performance of the base film, it is necessary to use a backcoating in the tape that realizes a coefficient of friction most suitable for the required format.
The Diamonex DLC coatings exhibit high hardness, a low coefficient of friction, chemical resistance and wetability.
NAVAIR concurred pending additional information on the flight deck coefficient of friction and emitter profiles, and recommended a slightly reduced catapult end speed.
They also wanted a material that compressed and recovered quickly and easily while providing a high coefficient of friction, superior durability, and UV and chemical resistance.
The coating enhances aluminum parts by adding increased hardness, maximum corrosion, abrasion, chemical and moisture resistance, mold release, high dielectric strength and low coefficient of friction. The brochure details the uniform coating thicknesses and tolerances of the product, which can be applied to parts of almost any configuration, weight, size or thickness, including close-tolerance parts.
