AI Thread Summary
The discussion revolves around calculating a 1:12 gear ratio using epicyclical gears, with participants sharing resources and equations. A helpful link to a PDF on planetary gear systems was provided, emphasizing the complexity and variety of configurations in epicyclical gear trains. The original poster ultimately found an alternative solution due to time constraints. The community expressed interest in learning about the alternative method used. Overall, the conversation highlights the challenges of working with epicyclical gears and the collaborative nature of problem-solving in engineering.

Trying to calculate how to produce a 1:12 ratio gear train with epicyclical gears. Can anyone send some equations or links to help explain how to do this? I have looked in textbooks and online and found many examples of achieving this with a simple compound spur gear train with 3 or less stages but nothing on how it works with epicyclical gears in series.
 
Engineering news on Phys.org
There are many possible configurations for a planetary train, and no single description fits them all. Baluncore has sent you a good link, but it is not exhaustive. You need to narrow the range of what you want to investigate, then maybe ask more questions if necessary.
 
Thanks to all who took time out to reply.
In the end we ran out of time and found another way to solve the issue
Figured i'd keep you updated :)

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 'Cantilever help'

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
