I love youtube recommending 644 subscriber accounts with such great information.

0:05 I don't need friends to have crazy ideas 🤪

Is there any advantage to use studs with two nuts instead of a bolt and one nut in terms of strength?

Can't believe there was a practical demonstration. Bravo!

That spec sheet, why can’t it give that number you calculated?

So what you’re telling me is that the grade 12.x ( I think it was 12.8) bolt I bought from Ace Hardware should be fine to hold my brake caliper bracket? Loved learning through your video!!

This is great stuff! I loved my applied materials and statics classes, we got to do these kind of test in labs.

As a dude who 3D prints stuff I design this kind of expanded explanation around what is a really simple concept is super helpful because engineers are often grumpy. Subscribed.

You're using a 1/4-in bolt to hold almost a 2-ton load? That's insane. I would never do this with anything less than a 17/64 size bolt.

Bluehill... I remember that software. Something about v2 being completely incompatible with v3, but i could be way off.

UA-cam needs more 5th grade science teachers. I commend you, fellow 5th grade science teacher.

Never thought of it that way before: average is about accuracy, standard deviation is about precision. Thank you!

being a software engineer, even the basics of mechanical engineering is so cool to me. thanks for making these vids!

what the fuck. 8.8 10.9 12.9 first number x100 = tensile strength in MPa first number x second number x 10 = yield strength in MPa

Cool explanation but you'd have to be an asshole to bring me the wrong bolt and not even tell me, at least get two if you get the weaker one, wtf man

Haha I love the idea that somebody would try to lift nearly two tons with a 1/4-20 bolt

So... to summarize... you just took 6:28 of our time to tell us that Grade 8 bolts are stronger than Grade 2 bolts? Do I have that right?

This was a more interesting video than expected - You should have put a picture of your tensile test rig in the thumbnail, I thought this was going to be a purely theoretical discussion but no, you actually tested this!

Now please do a worn serpentine belt on the lifting diagram!

It would be fascinating to hear about the metallurgy for TTY bolts that operate in the yield zone, such as TTY head bolts used on some motors.

loose

Stunning!!! There are no words. This is what kids and people should be doing. This makes my brain reverser enginneer engines and thinking of ford 6.0 engine and their failing head bolts that need to be studded. Wow!!!!!

Nice video and explanation!

While working in s large maintenance shop I liked to check hardware stock every week snd always ordered grade 5 for general use. Caution NEVER purchase any hardware, test or safety equipment from lack of quality control lying cheating communist china. Had way too many stripped bolts, heads break off and oaper thin flat washers.

Would need to watch this in metric😂

does the tread type have an impact 1/4 unc /unf? (1/4- 20 and 1/4- 28 tpi)

Great video! However, how does the threading factor into the yield strength? For example, if it were hanging by one thread, it’s not going to hold like you say. Also, the experiments showed the threads breaking before the bolt as might be expected. How do we dearth for threads, or, how many threads do we need to ensure the maximum pull performance? Related question, how much of the yield strength performance is provided by a ‘standard’ nut meant to work with that bolt (obviously if one used a grade 2 nut with a grade 8 bolt we should not expect top performance. This could be a whole video! ;-)

What about the difference between a Grade 8 and an A490? Or SAE bolts vs ASTM bolts?

Does elasticity degrade its load capability over time or no?

Great video! Love the format and the demonstration!

This has to be one of the most american videos ever. Not a single metric unit. Americans will do everything to avoid metric. 🦅

Awesome video! I will be watching more.

Nice demonstration. This is why I use fine thread fasteners with as little thread as possible on my race cars

This is only part of the picture. Besides the static failure, the designer should also consider the amount of acceleration, bolt pre-load, application environment and many more factors.

Thank you respectable bigga

Great video

Nice information.

sounds like your friend learned a bard lesson

Im subscriber 291. Ill never forget the day I subscribed to "Wild" Bill Fortney.

Cool. Can you make a metric version of this video?

Interesting, but can you speak English and not MERICA?

Real question is what's the production cost difference between them why make lower grade bolts at all ?

Make fasteners grade8 again! 😊

Thank you! Great channel. I used to make structural drawings for high rise buildings.

Show numbers in metric as well.

I learned never send cousin Larry to the hardware store

Can you do a video about how to specify the correct bolt torque when designing a new thing. Walk us through the rationale behind TTY, Torque + Angle, or simple Torque specification. How much clamping load do I need? How does direction of force (normal, sheer, hybrid) dictate the prescribed clamping load.

I knew all of this information, I have no idea why I just watched this 😂

Great lecture!
