Velocity and accleration diagrams

Click For Summary
SUMMARY

The discussion focuses on the complexities of drawing velocity and acceleration diagrams for slider crank and slotted crank mechanisms. Participants emphasize the importance of understanding the tangential and radial components of acceleration, specifically how to accurately represent these components in relation to each other. The need for clarity in determining the direction of the tangential component, which is drawn perpendicular to the radial component, is highlighted as a common source of confusion. Establishing conventions for clockwise and counterclockwise directions is crucial for mastering these diagrams.

PREREQUISITES
  • Understanding of slider crank and slotted crank mechanisms
  • Knowledge of vector components in physics, specifically tangential and radial components
  • Familiarity with drawing conventions in mechanical engineering
  • Basic principles of kinematics and dynamics
NEXT STEPS
  • Study the conventions for drawing velocity and acceleration diagrams in mechanical systems
  • Learn about vector decomposition in the context of mechanical engineering
  • Explore resources on kinematic analysis of slider crank mechanisms
  • Review examples of acceleration diagrams to understand component representation
USEFUL FOR

Mechanical engineering students, educators, and professionals involved in kinematic analysis and design of mechanisms will benefit from this discussion.

how do we go about deciding the directions while drawing the velocity and acceleration
diagrams for a given slider crank or slotted crank mechanism.while drawing the acceleration
diagrams,2 components -tangential and radial component need to be shown ,so
when we draw the tangential component perpendicular to the radial component,in which direction would we take the perpendicular?please tell me, as while drawing it is really confusing

Sorry buddy, my answer ll offer you no direct help.:redface:

That subject takes hell of a time to understand. Just keep reading & try to resolve your concepts, it gets easy afterward
 
but please ,let me know the conventions i need to follow while dealing with
this topic-it has so many directions-clockwise,counterclockwise.
