    What Is the Rotational Angular Momentum of a Barbell System?

    the manitude of Ltrans = r*psin theta right? so it would be .8kg*80rads/s*.525m? its wrong i tried -33.6 and positive 33.6 both are wrong :(

    What Is the Rotational Angular Momentum of a Barbell System?

    A barbell consists of two small balls, each with mass 400 grams (0.4 kg), at the ends of a very low mass rod of length d = 35 cm (0.35 m). The center of the barbell is mounted on the end of a low mass rigid rod of length b = 0.525 m (see Figure). The apparatus is started in such a way that...

    Solving Torque: R=9cm, F=18N, d=30cm

    what is the torque?? A disk of radius R = 9 cm is pulled along a frictionless surface with a force of F = 18 N by a string wrapped around the edge. At the instant when d = 30 cm of string has unwound off the disk, what is the torque exerted about the center of the disk? i tried...
