What are some good references or textbooks that can be used to learn more about this?
ОтветитьI'm a mechanical engineer and I approve of this video. Beautifully made.
ОтветитьI love the video thank you so much, is it ok if i took some part of it to publish a video in Arabic for my students 🙏
ОтветитьThese must be in every single school and uni. What a great effort and result. Thank you
ОтветитьWe can supply you especially big or high strength turmbuchles , produced according to your demand
ОтветитьThe nut factor
ОтветитьHuck Bolts are interesting too. They are hardly bolts in any traditional sense. Mack uses them on military truck frame rails.
ОтветитьNo .. they are bolted to do the math.. and stopped rivets..
ОтветитьI enjoyed this way more than I expected
ОтветитьIf nothing else, I learned a new word: centroid.
Ответитьnut factor
ОтветитьIn the first example of the force(s) being applied in parallel to the longitudinal axis of the fastener, would the springs representing the system not be in series? It would be great to model the system on a load frame and match empirical data to the theoretical prediction(s). Thanks for a great video!
ОтветитьIs there a formula that predicts the final Bolt Load (and hence, final Clamping Load) based on the original preload and final Applied Load?
ОтветитьThe first animation isn’t correct. The threads should be all the way through the plates.
Ответитьl0l the "nut factor" - I think im about to nut.
ОтветитьWelding is better tbh
ОтветитьMechanics understand this naturally.
Ответитьthis is the coolest video so far...

Thanks for the high quality videos. Better than any textbook available ! Wish these videos were here when I was an engineering student. Keep it up 👍!
ОтветитьPour a little of mineral oil and apply vibrations and we will see
ОтветитьThe nut factor
ОтветитьThey need to make all education material in the same way as this video. Well done!
ОтветитьCan they be improved? YES! Look up The TrueLoad Bolt, invented and patented by Rivington Stone. Stress distortion measurable with ABSOLUTE PRECISION!
ОтветитьHappy to learn my NUTS can hold down weight
ОтветитьI’ve gotta be honest, I broke at “Nut Factor” 😂 and then he continues with the nut’s load
ОтветитьDope video
Ответитьanyone with tips on increasing my nut factor? bust too soon most of the time
ОтветитьI was 100% with you all the way until you said the words nut factor
ОтветитьI graduated as an engineer recently and it's like I was stupid because this is really new for me to know
ОтветитьJesus fucking how good these videos are
ОтветитьDon't buy into this people, this is big bolt propaganda, threads aren't real!
ОтветитьVery well explained. The fact that, in a tension joint, the bolt does not experience any additional force until preload is exceeded is a bit counter intuitive but makes sense. I don't think the fake springs helped. It is the lifting force replacing the reaction force of the lower plate. A force diagram would be more accurate and clearer than fake springs.
ОтветитьExcellent video.
I've been using CAE to analyse bolted joints for a number of years now.
Some of the engineers in the teams I worked in knew nothing about how bolted joints work. One of the chief engineers thought i was talking another language when I told him that the bolt sees near no load when a joint is in tension and doesn't open.
I had to draw him a joint diagram before he was finally convinced.
Bolt Science is a good website that I've used in the past.
My God, you are a bloody genius! GOD BLESS YOU!
ОтветитьYou only use a single lock washer on the side of the nut or bolt you intend to torque. The other should be held stationary. You can use a washer on both sides to make torqueing the fastener more consistent, but using two lock washers, just let's the joint slowly back off. Because both ends are being pulled away from each other evenly. Instead of off center.
ОтветитьI was in the toilet and realized that am watching a 18 minute video about a bolt and I said MAN no female is watching like I watch this video
ОтветитьAll this talk of joint members, stiffness, stripping, pre-loads and full loads is hardening my bolt...
ОтветитьI wish i could be an engineer.
ОтветитьSurprised that bolts do not strip easier. See cranes carrying heavy loads but they hold. Safety inspectors check annually. Appreciate the explanation.
Ответитьgreat quality renders make the explanations dummy proof :)
Ответитьheh heh heh, pre load, heh heh heh
ОтветитьFlat washers on nuts and bolt heads must affect shear force more than clamping force. Am I correct?
