-NO mg IN FBD 3. A cylinder C, having a mass of 0.5 kg, moves along a grooved horizontal slot. The slot is in the form of a spiral, which is defined by the equation r = (0.1000) m, where is in radians. If the arm OA rotates in the horizontal plane with the constant rate shown, determine the force the arm exerts on the cylinder at the instant -rad. Neglect friction and the size of the cylinder. ms 0.5kg r= (oloo 6) m FB0 3 r=0.10 = 4 rad/s Top View
