Studying for an exam right now that asks about 'Cyclic variation in torque transmission for a Hooke's (universal) joint operating at a given angle' and honestly your video is the only thing that actually SHOWED me how it looks irl. Thank you for that!
You should probably rotate the U-joint 90 degrees, and test all 4 orientation to your torque gauge because your reading should depend on where the U-joint is in its rotation. (You'll need to lower your base torque though) You'll likely find an oscillation between high and low readings as you go through the 4 orientation (caused by the speed oscillation in U-joints). Here's a link to U-joints on Wikipedia (they provide speed oscillation graphs, so the torque oscillation would be inverted): en.wikipedia.org/wiki/Universal_joint
Thank you for this video. It confirmed my suspicions that went working at an angle that adds extra friction to overcome. It looked like the 45 degree angle clicking was about 22% to 37% lower than the 0 degree angle. Working on a Kawasaki 454 LTD motorcycle and I didn't want to disconnect the coolant lines: therefore, I used a universal adapter at 45° which had me searching for a video like this one.
After much searching I found a formula that specifies what torque setting you should use on the wrench to apply the desired torque at the fastener. TA = T/cos(A) Where TA is the torque set on the torque wrench, T is the desired torque at fastener, and A is the angle of the swivel socket. I haven’t used this against your numbers in your test.
One question I have, digital torque adapters, do they work if the u-joint is behind the adapter? Would love to see a video on that and it looks like you already have one.
Thanks. Good to have confirmation it has an impact and a big one at that!

I am very happy I could help in some small way! Best of luck on the exam!

Glad I could help in some way! I don't think I'd call my testing scientific. More just proving the idea.

I haven’t used this against your numbers in your test.
Also, impact universal wrench has less play than the standard universal wrench is more accurate.
Thank you for this video.

Hmmm.... Maybe this is why the wheels keep falling off my truck. 😆
At least it’s consistent, that means an equation is next
Love science. Results don’t lie.
Wow
Interesting have issues at work because of this.
Not much changes the tools setting. Short video shows. 8:/b5b38712050c1 CA1234
Thanks for this!
Thanks for watching!
