Designing a Mechanism for Two Half Circles' Synchronous Rotation

  • Start date Start date
AI Thread Summary
A mechanism is being designed for two half circles to rotate synchronously, utilizing springs and a single input rotational source. The discussion includes ideas about incorporating a crank and slider system to facilitate the opening and closing motion. There is a request for guidance on effectively using springs within this mechanism. Additionally, participants are prompted to consider the purpose of the half circles' movement and whether they function as mirror images. Understanding these dynamics is crucial for developing the mechanism effectively.

Regards Respected Teachers and Members

I would like to draw a mechanism that two half circles should rotate synchronous close and open as a result gears will rotate at same Value , i would like to use springs in this mechanism between circles , the other idea i know that use crank and slider , link from slider attached to both circles as a result opening and closing will happen , but i would like to use springs and the input rotational source should be one as shown in figure

Need guidance about spring using

Thank you

I think we need to step back and look at why the mechanism needs to move the two quadrants or part circles. What will the quadrants be doing ?

Do the part circles move as mirror images about some plane ?
 

Thread 'Bubble formation in 4 mm gap vessel'

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 '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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
