Analysis of torque vertical on string model

Different to other motion of torque,motion the torque modeled by mckenna (1999) is the motion of torque into a vertical direction,a consequence of the imposition of downward. mckenna lowering the model of two pieces of rope in fastening on a beam then in hanging,then mckenna replaces the parameters with forensic data from tacoma bridge,to analyze a wave of what happened at the bridge collapse that resulted in the bridge. in this research will be shown that the solution of the equation of vertical torque from the results of having a conspicuous disparity linearization with a numerical solution. © 2016 penerbit utm press. all rights reserved.
