Snakes On An Inclined Plane

Physics 235 Snakes on an Inclined Plane A June 8, 2009 hold in LiveScience magazine describes how David Hu and a team of researchers at gallium technical school headstrong how snakes move on a flat surface. Their findings let on that the abrasion of snakes belly outperforms, on with weight distribution, is the main sweat of their forward loco feat. These seemingly multifactorial attempts of living creatures can be interpreted and explained with the Newtonian physics of a general chemical mechanism class. Dr. Hu and his team devised a theoretical form to describe snakes movement by observant their slithering and experimentally measuring their skins coefficients of friction. To do this they first interrogatoryed the snakes scale friction by placing them in 9 different orientations from 0° to 180° on both(prenominal) a melted inclined planing machine and a framework covered plane whose roughness matched that of the snakes scales. The touch of the plane was therefore lifted until the snakes began to slide. For the coarse board, they found that the unconscious mind snakes slid forward quite a easily but were untold more resistance to skid tailwards or towards their flank. On the smooth board, the snakes slid in each pleader with the same ease.

The static friction coefficient for the snakes belly scales was obtained from the critical slant at which the snakes began to slidethe go being the smallest if the snakes were glide forward, mediate for sliding trailwards and the greatest for sliding toward their flank. This difference in the order of magnitude of friction depending on the direction in which it is measured is called fr ictional anisotropy. The interaction ming! led with the frictional anisotropy of a snakes belly scales and its natural physical structure forces determined the snakes motion. A snakes center of mass was determined to be a function of the speed and size of its body waves, with the motion of the center of mass almost completely translational. To test their model and predict the snakes movement on various...If you want to retrieve a full essay, order it on our website: OrderEssay.net
