So I have to design this linkage system. How it works is, when the link 1 receiving torque from the gear system is blocked from moving, the link 2 transfers it's torque to the next 4 bar linkage via link 3. When link 4 is blocked, the same thing happens. What is confusing me thought is how is the torque transferred from the first 4 bar linkage to the second? In what ratio that is? And if say, I had to compare this compound 4 bar linkage with another linkage system, what calculations do I base the comparison on? Force distribution analysis? If yes, I need some confirmation of force distribution calculations I have been doing on this. Because I have no way of validating If I am going in the right direction. Long story short. I need help with the force distribution calculations along linkages with its free body diagram. I need help with torque transfer mechanism in this linkage design. And I need some sort of method for comparison (even a software resource would help) Looking forward to a reply.
