Fall factor of 2, 80Kg mass, only 8.6KN transferred to the mass. Must be under 12KN. Over 12KN the body get seriously injured. I'm working on a Out/In equation, just to play with some simulations in MatLab. input=Force, Output=elongation input=velocity, output=force etc. Next step, calculate the spec wich the comercial rope are offered,... for example, bluewater accelerator 10.5: 8.6 KN, 33,1% dyanmic elongation,...etc. Thanks. ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
