Bar AB is pinned to the fixed support at A, and the collar B is pinned to the bar at its opposite end. The bar CD can slide freely through the collar at B. At the instant shown, bar AB is horizontal, /= 1.2 m, s = 1.07 m, 0 = 60°, and wAB= 40 rad/s.

The collar at C is pin connected to CD and slides freely along AB. Assume the counterclockwise rotation as positive. 2. Determine the angular acceleration of rod CD at this instant.

At the instant shown, rod CD has a constant clockwise angular velocity WCD- The collar at C is pin connected to CD and slides freely along AB. If the velocity of point Care 7c = 1.3 m/s, the relative velocity of C to A in the rotating coordinates (C/A)zy = (VC/A)zy (0.8667 -0.500) m/s, and the position vector C/A=0.73(0.8667-0.5007) m, -(0.73) (0.500) knowing that (vC/A)zy WAB 0.866 determine the angular velocity of link AB, WAB.

Hello can you please show me how to do this useing relative motion analysis. I don't think I'm doing the steps totally correct. Thank you in advance.

At the instant shown, the AB bar has an angular velocity of 4 rad/s and an angular acceleration of 2 rad/s2. Determine the angular velocity and angular acceleration of the CD bar at this instant. The C-ring is pin-to-CD connected and glides freely along AB. WAB = 4 rad/s CAB = 2 rad/s? A 60° -0.5 m- 0.75 m D B

An external drive system actuates the mechanism by applying a moment M at bearing D. At the instant 0 = 45°, the magnitude of the velocity vector of point C is 14 m upward and to the left and the angular acceleration of link CD is 50 rad in the CCW direction. Determine the y-component of the acceleration vector of point G in m at this instant. Consider L = 6 metres. E y +. M
