PROBLEM #3 (40 points) The 1-kg slider A is pushed along the curved bar by the slotted bar. The curved bar lies in the horizontal plane, and its profile is described by r = 2 (+1)m, where is in radians. The angular position of the slotted bar is = 2 trad. Determine the radial and transverse components of the total external force exerted on the slider when = 120°. Ꮎ
