Torque & Angle Explained with a Stress / Strian diagram

[ta2stop]

awsome explanation MR.PETE....thanks for that info and putting on video for the world to understand ....great graph and calculations ......!!!

The videos I make are driven by phone calls I receive. When I made the 3.4 head gasket video I had hundreds of calls & had to explain angle and torque-to-yield fasteners to most everyone. I analyze torque and angle data every day in an engine plant and it is immensely important to understand what it means. The data can tell me if there is a cross-threaded fastener, chips in a hole, or a bad part. It is an intricate science, I'm not an expert, but I tried to make it easy to understand. Thanks!

Great vid, CoolCarsHotGuitars. What's your opinion of electronic torque wrenches "with angle"? IOW, digital readout torque wrenches that can apply angle specs as well as torque. Are these tools "smart" enough to know the difference between deflection of the torque wrench handle and the turning of the actual fastener itself--through an angle, after the preliminary torque value has been met? (Deflection of torque wrench handle isn't a problem with a mechanical torque angle gauge.)

[CoolCarsHotGuitars]

Any electronic tool is fine as long as it is calibrated at the recommended interval. I use some electronic torque wrenches and they are pretty neat..and yes they can accurately measure angle. A good one is very expensive but the manual method is just as good.

tell us bout you! :)

Nice video!

But is there som kind of diagram to get the right angle?

[CoolCarsHotGuitars]

Not that I know of. There are so many different material / thread / variable combinations it would be a huge chart. That is why it is a calculation for each application.

Very informative Professor Pete. Now I know how to torque my nut at the right angle thanks to you. And to think I was doing it wrong all these years. :D ~Todd

[CoolCarsHotGuitars]

I use to think you were crazy but now I can see your nuts!!! : > }~

Hey great job on the the torque and angle topic, vary nice discription! I'm a license tech and I even learned a little something from that! Great job thanks for sharing.

[CoolCarsHotGuitars]

Thanks so much. Torque and angle is someting that is very important, but rew people understand it. It's great to hear good things from a professional such as yourself. Just wondering....what did you learn?

[Rasd4Metta]

@CoolCarsHotGuitars Well I knew about tensile strength and yielding the bolt when using torque to yeild but the way you showed the explaned the theory behind it made me remember back when I was tought it, I use the torque to yield on most of the fastener I torque since all the new vehicle use it, but since i don't use theory everyday you kinda tend to lose it over time. So I guess it was more of a refresher course for me lol

i just gained XP points.... lol

[CoolCarsHotGuitars]

Ok you got me.....what are XP points?

[touchsmart0]

@CoolCarsHotGuitars lol its a video game thing .... XP is experiance

[CoolCarsHotGuitars]

Goes to show you how much time I spend in the shop instead of playing video games. The last video game thing I remember is that a pretzel comes after the watermelon in PAC-MAN......lol

[touchsmart0]

@CoolCarsHotGuitars lol.... dig dug?

[CoolCarsHotGuitars]

I spent hours on Crazy Climber and Defender. Centipede was high tech to me....maybe that's where I got carpal tunnel....lol

[touchsmart0]

@CoolCarsHotGuitars haha... man how old are you???

Thank you
