SUMMARY

The forum discussion centers on deriving the kinematic equation for a 4-bar linkage mechanism to determine the angular position of a cylinder at various theta values. Participants emphasize the importance of providing free body diagrams (FBDs) and relevant equations to facilitate the solution process. The discussion highlights the need for clarity in presenting the problem and encourages users to share their attempts at solving the equations. The context involves design automation for fixture design, indicating a practical application of the kinematic analysis.

PREREQUISITES
  • Understanding of kinematic equations specific to mechanical linkages
  • Familiarity with free body diagrams (FBDs) in mechanical engineering
  • Knowledge of 4-bar linkage mechanisms and their configurations
  • Proficiency in using design automation tools for fixture design
NEXT STEPS

Welcome to the PF. What is the context of your question? Is it for a school project?
 
i didnt get ur question

yes i need an help to solve this...

Okay. Thread moved from ME to the schoolwork section of the PF. What are the relebant equations in approaching a problem like this? Can you show us how you are setting up the equations to solve the problem?
 
no move to ME itself

No. Show your attempt at a solution. We do not do your homework/coursework for you here. That's part of the PF Rules (see the link at the top of the page).

That's weird -- where did your diagram go?
 
Here i attached the schematic diagram of 4 bar mechanism.

We are working on design automation for fixture design for that purpose we need to solve this kinematic equation.

Show us your free body diagrams for the linkage. Show us your equations that you derive from the FBDs. We don't do your work for you here at the PF.

here i have attached the free diagram as well as main diagram, from that we need to find the equation from the given data, please see both the attachment, now totally i have attached 3 drawings in jpeg file...
