Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...

The friction between a silicon ball and silicon wafer was measured in the experimental set-up shown on the left. The new research demonstrates that there is a direct relation between two effects: the ...

SOME special experiments were made with blocks of small area. The brake-blocks generally used in these experiments were 12 inches long, by 3 inches wide, giving a surface of 36 square inches; the ...

Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

Excessive resistance against the movement of adjacent plies, or ply-ply friction, can lead to process-induced defects during hot press forming of thermoplastic composite laminates. To avoid the ...

An interdisciplinary research team of the Institutes of Physical Chemistry and Physics of the University of Freiburg and the Max Planck Institute of Biophysics in Frankfurt-am-Main has discovered a ...

Probably everyone is familiar with the phenomenon: water drops cling to a pane of glass, if it is tilted out of the horizontal plane. Only when a certain angle is reached they slide off. This raises ...

For most people, the first thing that comes to mind when they think of Leonardo da Vinci is the Mona Lisa, or his sketches of the Vitruvian man. Fans of pulp fiction or popular cinema might even find ...

Friction is the force between two surfaces that are trying to slide across each other. Friction always slows down a moving object. The amount of friction depends on the material the two objects are ...
