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 ...

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

You can't escape friction. The force that resists motion between two objects that are in contact with one another exhibits itself all over the place: in between your engine's rod bearings and its ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

You know that two surfaces mate, but what is a friction clutch or brake? Using friction has been the most popular way to engage and stop loads since the 1800s. Surfaces interact with ...

The dynamic evolution of an elastic medium undergoing frictional slip is considered. The Coulomb law modeling the contact uses a friction coefficient that is a non-monotone function of the slip-rate.

EVANSTON, Ill. -- Most people have experienced the hair-raising effect of rubbing a balloon on their head or the subtle spark caused by dragging socked feet across the carpet. Although these ...

Back in the 1980s, Pacific Bearing Co. (PBC) invented and commercialized plain bearings, which were sized to be interchangeable with linear ball bearings. Plain bearings worked very well in certain ...
