A mechanical aim rotates in the vertical plan about point O. Theslider P (m = 2 kg) is drawn toward O with a constant speed (?̇) of0.5 m/s through the rough slot (friction coefficient µ = 0.1) bypulling on the free end E of the cord. At the instant when r = 0.25m, the arm is rotating with a constant speed (?̇) of 10 rad/s inthe clockwise direction.
When the slider is oriented at an angle of θ = 30° from thehorizontal:
a) Plot the free body diagram for P, using r-? coordiantes; showpositive r and ? directions (4 points)
b) Determine the normal force between the slider and the slot, in N(7 points)
c) Determine the tension in the cord, in N (7 points)
d) Which side (A or B) is in contact with the slider? Why? (2points)
