Question

The slotted arm below is rotated radially in the horizontal plane with the rotation governed by 8-0.2t + 0.02t3 where θ is in radians, t is in seconds. Also, the power screw in the arm controls the distance r from 0 according tor 0.2+0.04t2, r is in meters and t is in seconds. The power screw can be treated as a cord (cable) and the Mass of the slider is 2kg. Determine: a) Acceleration of the slider B, for the instant when t-1s. b) For this instant, determine the tension T in the cord and the magnitude N of the force exerted On the slider by the sides of the smooth radial slot.
