The spool, which has a mass of 4 kg, slides along the rotating rod. At the instant shown, the angular rate of rotation of the rod is θ = 6 rad/s and this rotation is increasing at θ = 2 rad/s2. At this same instant, the spool has a velocity of 3 m/s and an acceleration of 1 m/s2, both measured relative to the rod and directed away from the center O when r = 0. 5m. Determine the radial frictional force and the normal force, both exerted by the rod on the spool at this instant. |
