Help with this mechanism (acceleration with graphic method)

Click For Summary
SUMMARY

The discussion focuses on calculating acceleration using graphical methods in a mechanical context, specifically involving a two-link system labeled AB. The user has successfully created a speed diagram but is uncertain about the accuracy of their acceleration diagram, particularly regarding the acceleration of point "G" and the direction of rotation, which is confirmed to be counterclockwise. The need for clarity in plotting and calculating acceleration in mechanical systems is emphasized.

PREREQUISITES
  • Understanding of kinematics in mechanical systems
  • Proficiency in drawing velocity and acceleration diagrams
  • Familiarity with two-link mechanisms in robotics or mechanical engineering
  • Knowledge of counterclockwise rotation and its implications in motion analysis
NEXT STEPS
  • Study graphical methods for calculating acceleration in mechanical systems
  • Learn about the principles of velocity and acceleration diagrams
  • Explore the dynamics of two-link mechanisms in robotics
  • Investigate the effects of rotation direction on acceleration calculations
USEFUL FOR

Mechanical engineers, robotics students, and anyone involved in kinematic analysis of two-link systems will benefit from this discussion.

Hi guys!
I have problems with this mechanism...finding the aceleration with graphic method.

I already have drawn the speed diagram and the values of all of them.

But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the acceleration of "G"

Thank you.
Could you show us your work on velocities?
