Snakes On An Inclined Plane

Physics 235 Snakes on an Inclined Plane A June 8, 2009 word in LiveScience magazine describes how David Hu and a team of researchers at atomic number 31 technical school headstrong how snakes move on a flat surface. Their findings let on that the clash of snakes belly racing shells, along with weight distribution, is the main sweat of their forward loco apparent motion. These seemingly ent wobbled attempts of living creatures can be interpreted and explained with the Newtonian natural philosophy of a general chemical mechanism class. Dr. Hu and his team devised a theoretical deterrent example 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 silver-tongued inclined woodworking plane and a framework covered plane whose roughness matched that of the snakes scales. The progress 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 ofttimes 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 angle being the smallest if the snakes were slue forward, mediate for sliding trailwards and the greatest for sliding toward their flank. This difference in the order of magnitude of friction depen ding on the direction in which it is measure! d is called frictional anisotropy. The interaction amidst the frictional anisotropy of a snakes belly scales and its home(a) 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
