1. The problem statement, all variables and given/known data A barbell consists of two small balls, each with mass 550 grams (0.55 kg), at the ends of a very low mass rod of length d = 20 cm (0.2 m). The center of the barbell is mounted on the end of a low mass rigid rod of length b = 0.3 m (see Figure), and this rod rotates counterclockwise with angular speed 110 rad/s. In addition, the barbell rotates clockwise about its own center, with an angular speed 90 rad/s. (a) Calculate Lrot (both magnitude and direction). (b) Calculate Ltrans, B (both magnitude and direction). (c) Calculate Ltot, B (both magnitude and direction). 2. Relevant equations I=m*r^2 w=2pi/T Lrot=I*w 3. The attempt at a solution i dont know where to start because it is rotating while it is moving a distance at the same time?!
