WebMay 19, 2014 · Tribological tests (friction and wear tests) were performed using UMT-2 (universal Micro Tribometer, CETR, Campbell, CA, USA) in a ball-on-disk setup. The typical number of sliding cycles vs. coefficient of friction (CoF) plot is the outcome of the sliding tests, where CoF values are derived with respect to the corresponding sliding cycles. WebSo the speed of the center of mass is equal to r times the angular speed about that center of mass, and this is important. This you wanna commit to memory because when a problem says something's rotating or rolling without slipping, that's basically code for V equals r omega, where V is the center of mass speed and omega is the angular speed ...
