How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine ...

Especially in micromechanical parts, where only small forces are at play, a vanishing static friction can lead to hugely improved levels of efficiency.

1.4 The role of lubricants Science notes: Friction basics (key takeaways and vocabulary) 2 Friction at the nanoscale 2.1 Intermolecular forces 2.2 Friction in mechanical micro- and nano-systems 2.2.1 ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is ...

ASK THE BUILDER | No, you don't need poured concrete or mortar to build a strong retaining wall.
