Kinematic equation for 4-bar linkage

  1. Dec 3, 2009 #1
    Looking For Help to derive the kinematic equation for the 4-bar linkage shown; (to find the angular position of the cylinder at different values of theta )

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

    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......
