A strange behavior of friction
The Physics Teacher, 1999We investigate the effects of dry, sliding friction between a felt-covered wood block and a wooden table. By measuring the applied force and the acceleration of the block, we experimentally determine the force of kinetic friction and find that it is constant when the applied force is larger than a terminal frictional force Ft=μtmg.

Frictional Behavior of Polystyrene
The Journal of Chemical Physics, 1967The frictional coefficients of three fractions of polystyrene, each of sharp molecular-weight distribution, have been determined both from diffusion and sedimentation velocity experiments in cyclohexane at 35°C and in cyclohexane at 25°C. The coefficients obtained from the two methods agree within experimental error.

The Frictional Behavior of Coated Guiding Archwires
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2002The vast range of orthodontic wires made of different alloys makes it increasingly difficult for orthodontists to judge them. Coated orthodontic wires form a group of innovative guiding archwires.In the present in vitro study the frictional behavior of eight coated wires of different dimensions was investigated in archwire-guided canine retraction in ...

An elastoplastic friction compensator with improved static friction behavior
2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2016Mahvash and Okamura's elastoplastic friction compensator is one of successful friction compensators for robotic joints with compliant transmissions. A limitation of the scheme is that, in the static friction state, the compensator continues commanding non-zero output force, which hampers the system's reaction to external forces.

Friction Behavior in Microsystems
2011In active microsystems, low lateral propulsive forces act under high contact pressures, thereby requiring a low friction coefficient ??for successful operation. The maximum acceptable friction coefficient is determined by the available driving forces.

Nanoscopic friction behavior of pharmaceutical materials
International Journal of Pharmaceutics, 2007The characteristics of various pharmaceutical dosage forms are influenced by surface properties such as the friction behavior. For example, die wall friction is a key issue in developing a solid dosage form. However, the friction properties are not completely understood mainly because of the lack of fundamental measurements.

Modeling of dynamic behaviors of friction
Mechatronics, 2008This paper deals with modeling of dynamic behaviors of friction in the sliding regime. Using a hydraulic cylinder, friction characteristics are experimentally investigated under various conditions of velocity variation. The friction force of the hydraulic cylinder is measured based on the equation of motion using measured values of the pressures in the

Frictional behavior in superconducting coil
IEEE Transactions on Magnetics, 1985Experiments were made to obtain information on the role of friction in instability of superconducting coil. We constructed a pin slide type device for friction test which works at cryogenic temperature. The pin slides on the inner most part of the coil wound by Nb-Ti-Zr-Ta conductor.

Frictional Behavior of Textile Fabrics
Textile Research Journal, 2000In this paper, the dynamic response for sliding friction is considered through dynamic models. A new interpretation of the non-uniform sliding phenomenon response is given, based on new topographic details of the fabric surface in front of the leading edge of the sled in movement.
