Based on the hardware device and the generated friction coefficient, a rendering method combining electrovibration and ultrasonic vibration is introduced. Evaluation experiments on the tactile device ...

The friction coefficient for the MLB one turned out to be 20 percent lower than the level for the NPB ball. That means major league balls are 20 percent slicker in a pitcher’s hands.

We review the historical and modern understanding of the most basic equation of friction, Amontons' law, which describes phenomena that were already understood and studied by Leonardo da Vinci 500 ...

Friction is a materials property. Basically, it is the force that resists the sliding motion of one surface against another. Contaminants, such as liquids, can change this value. The coefficient ...

Normal and shear forces were measured as a function of surface separation, D, between hydrophobized mica surfaces bearing layers of a hydrophobic−polyelectrolytic diblock copolymer, poly (methyl ...
