      Doesn't matter where you get your degree from if you can apply things you learn constantly. A degree is just an entry ticket into whatever field you love. Real learning happens once you're actually in the field. An essential concept in teaching (and therefore learning) is to "Demonstrate" something.

      @@alouisschafer7212 Wouldn't be so sure I've seen OEMs design trash before. I got an ebike from China with a 20mm through axle fork and an adapter for a M12 threaded axle motor. It was sold like this as a kit. Why is this a problem? Well, as far as I know, electric motors need electric power. And if your dropout is 20mm with no thread and the motor itself has an M12 threaded axle, you're forced to use their wacky "20mm diameter to M12" adapter covering each end of the motor axle to even mount it. No way for any cable to come into/out of the motor axle. So it was literally impossible to mount and connect. Again, they made this kit specifically and sold it like this! I contacted the vendor, he admitted this and gave me a partial refund...so never depend on designs or think you can't improve stuff...

    Having repaired and built hundreds of driveshafts from very small to very large , I did learn in the 1970s that the input and output shafts don’t need to be parallel. The angle of each U-joint must be the same though, and they must be inplane with each other.
    GM did this with the double Cardin U-joints they used in their upper end cars.
    This is, though, by far the best demonstration of U-joints I have ever seen.

    I just fixed the PTO water pump driveline on our water truck myself because no one would believe me that the shaft out of phase was the cause of multiple pump shafts breaking. If I knew about this video, the boss would have made the guy who put it together out of phase fix it. At least if I show them the video now, they won't be able to say "it's just a coincidence that we haven't broken another pump shaft in years". I don't want to wait years to prove I'm correct either.
