Position Loop Equation (Kinematics)

AI Thread Summary
The discussion focuses on deriving the position loop equations for a solar panel deployment mechanism attached to a satellite. The user has defined the lengths of components but is struggling to formulate the y loop equation in a rectangular coordinate system. They are considering whether to switch to local, global, or natural coordinate systems for a solution. Attached files include a system drawing and a reference document for similar mechanisms. The user expresses frustration over the lack of responses to their inquiry.

What will be the position loop equation of the attached file. The system is of Solar Panel Deployment attached to Satellite Body .
The lengths are
AB = Yoke = a
BC=CD=DE = Solar Panles = b

I have been trying to fine position loop equations (i.e x & y ) in rectangular coordinate system but y loop equation is not achievable.
Should I try something in Loacal /Global/ Natural coordinate system.

Two files are attached ...one is of my system's drawing
Other one is a reference document of analysis of this kind of mechanism which is at

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
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...
