Pedro Reis, head of the Flexible Structures Laboratory at EPFL&#8217;s School of Engineering, rolled up a piece of fabric and placed it under the machine to stop it from moving. After he saw how well the rolled-up fabric worked as a vibration damper, he got to thinking. He spoke with Samuel Poincloux, a postdoc at his lab, about his idea and they soon realized that the physics behind a piece of rolled-up material undergoing deformation is actually quite non-trivial. They set out to model the process, but given all the different variables involved, they decided to first simplify the problem. Instead of using rolled-up fabric, they started with a layered object possessing a similar geometry: a book. &#8220;For our experiments, we used flexible plastic sheets that we stacked up like the pages in a book, so that we could adjust and measure their collective properties,&#8221; says Poincloux.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-06-friction-pages.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Modeling the friction between pages in a book<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It all started with a shaky washing machine.
