Particular attention is given to characterizing the steady shapes that arise in static and dynamic rolling configurations. In both cases, above a critical value of the forcing (either gravitational or centrifugal), the ribbon assumes a two-lobed, peanut shape similar to that assumed by rolling droplets. Our theoretical model allows us to rationalize the observed shapes through consideration of the ribbon\u2019s bending and stretching in response to the applied forcing.<\/p>\n\n\n\n<p class=\"tw-text-wide has-small-font-size\">See paper here:&nbsp;<a href=\"http:\/\/math.mit.edu\/~bush\/wordpress\/wp-content\/uploads\/2012\/10\/raux_ribbons_prl_2010.pdf\">Raux, Reis, Bush &amp; Clanet_2010<\/a><\/p>\n\n\n\n<p class=\"tw-text-wide has-small-font-size\">PRESS: \u00a0<a href=\"http:\/\/web.mit.edu\/newsoffice\/2010\/rolling-ribbons-0908.html\">MIT News<\/a>\u00a0<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":5415,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[],"class_list":["post-5246","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-misc","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The dynamics of rolling ribbons - John W.
