What Track Should the Second Disk Follow in This Mechanism?

AI Thread Summary
The discussion centers on designing a mechanism that moves a piece vertically using a rotating second disk on a stationary disk. The second disk's rotation pushes a red pin, facilitating the vertical motion of the piece. The main challenge is determining the appropriate track for the second disk to achieve the desired movement. Participants suggest plotting a graph of radial pin position against the disk rotation angle to clarify the mechanism's function. A request for a clearer diagram indicates confusion about the design's objectives.

Hello,
I am trying to design a mechanism that moves a piece towards the center of a disk by rotating a second disk as described in the picture below.
There is a stationary disk which restricts the motion of the piece, so it can move vertically only. There is also a second disk that it is located on the first one and it can rotate. As it rotates, it pushes the red pin and causes to the vertical motion of the piece. So far in theory.
I am struggling to figure out what is the right track of the second disk, or any track will go?

Start by plotting a graph of radial pin position against disk rotation angle.
 
Can you provide a better diagram? I really cannot follow what you hope to accomplish here at all.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
