R13-8. 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 =6 rad/s and this rotation is increasing at = 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 = 0.5 m. Determine the radial frictional force and the normal force, both exerted by the rod on the spool at this instant.

Question
R13-8. 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 =6 rad/s and this rotation is
increasing at = 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 = 0.5 m. Determine the radial frictional
force and the normal force, both exerted by the rod on the
spool at this instant.
r=0.5 m
6-2 rad/s²
6 = 6 rad/s
Prob. R13-8
v, - 3 m/s
a, - 1 m/s²
