Unformatted text preview: θ are given, determine the magnitudes of the roller’s velocity and acceleration at the instant θ = θ 1 . Neglect the size of the roller. Also determine the velocity components V Ax and V Ay of the roller at this instant. The rod to which the roller is attached remains vertical and can slide up or down along the guides while the guides move horizontally to the left ( a = 0 . 3 m, b = 0 . 2 m, ˙ θ = 0 . 5 rad/s, ¨ θ = 0 rad/s 2 , θ 1 = 30 ◦ ). 3. For a short time the arm of the robot is extending so that ˙ r remains constant, z = bt 2 and θ = ct . Determine the magnitudes of the velocity and acceleration of the grip A when t = t 1 and r = r 1 (˙ r = 0 . 45 m/s, b = 1 . 2 m/s 2 , c = 0 . 5 rad/s, t 1 = 3 s, r 1 = 1 m). 1 Figure 1: Question 1 Figure 2: Question 2 Figure 3: Question 3 2...
