I have a problem where I need to determine the load of each bearing in a system comprised of three shafts. I have two questions regarding this:
- There are three shafts connected with 2 couplings. If I consider the 3 shafts as one shaft the problem is statically indeterminate. Is it reasonable to examine each shaft individually?
- There is an input shaft, transfer shaft, and output shaft. The input shaft is connected to a motor applying a torque on it. Do I need to consider this when making my FBD of the system? I have gotten mixed answers from colleagues
I have a picture of the system if it would help but I cannot figure out how to add it so let me know if you would like to see it - Thank you to comments for helping
Red represents the couplers and the grey rectangles are bearings. The middle two are kept in a bearing block. The long red rectangle is a torque transducer which is mounted to ground. Hopefully you can see the black lines indicating where each shaft would end.
