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 ...

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 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

Keywords: Seismic performance. Nonstructural components. Static friction coefficient. Kinetic friction coefficient. Rigid blocks. Block-type components. Tilt and pull tests. Dynamic analyses.

Really, this is the experiment I wanted to start on. How does friction work in Bad Piggies? Let me start with a quick summary of my experiments so far. Scale. For the size of stuff in Bad Piggies, I ...

In "Friction," tribologist Jennifer Vail shows how the fundamental force that resists motion keeps driving us forward.

Picture yourself at a busy pedestrian crossing. When the light is red, everyone waits -- until one person starts to cross. Soon, others follow, and eventually everyone follows the crowd and crosses.

What friction rate should we use when designing a residential duct system? is 0.1” of water column safe? When it comes to understanding friction rate in residential ductwork design, Allison Bailes III ...
