square balls?

Dear Mr. Corey, first I would like to congrats your content. This is very dynamic guide to determine the dimensions of the mecanism. I read your article on your website and I have one doubt. Why did you use the distance 30,49 inch as cylinder moment arm? I thought that the cylinder moment arm would be the 39,5 inch. Can you help me to understand this point please?

So I'm curious why you put so much distance between the heater and the hot tub? Is there some heating reason I"m missing?

Love it!

5:51 excellent matrix

That kid rules. His coaster rules. I'll bet his rides will get better and better. Mentorship is a beautiful thing. Well done, Mentored Engineering.

Interested in how you increase SM without increasing the area moment of inertia...did you post a video that explains this? Also, what would be benefit of this? Thanks.

is there a set distance that the gusset needs to travel along the horizontal bar to be sufficient enough for support? say on a 20ft long carport roof?

I know this is an older video but I am hoping it is still monitored and you can help me out here. I have went down the bit hole of planetary gears and have watched several different videos and I am confused by what I think is conflicting information (more likely me just misunderstanding) From online the gear ratio from sun to stator/carrier GR = 1 + (number of ring teeth/number of sun teeth). I believe the gear ratio also = driver speed / driven speed. In the case of a locked ring gear, and using the teeth number from your examples, the gear ratio, GR, for from sun to stator would be = 1+ (100/20) = 6. If it is also true the GR = driver speed / driven speed, then the stator rotational speed would then be = driver speed / 6, or 16.667%. In your example, you arrive at the fact that the stator is rotating at 40% of the sun, which is different. Can you possibly clear this up for me? Like I said, I figure I can chalk this up to my misunderstanding but I like answers haha

I thought he hit the tree

What is the calculation or formula used for % of decision column?

Bros gonna mess his back up that turn is ROUGH

What happened to you buddy!

Tip: to prevent those moments where the passengers head goes off the seat, make the track turn at most 40° into the pivot point! The g forces would be curved so if the track is facing that curve more that it is in this video, it wouldn’t push the passenger like that.

Thanks

why doesn't it turn inro the corner rather than turning out during the corner

Solid advice 💯

The input is carrier and output is ring right?

We'd love to make all gussets perfect, but there are other design constraints like using tabs & slots for alignment and easier manufacturability! Can't really use those with a side gusset. Any tips on a least bad gusset design when you want to use tabs and slots with the gusset?

Bike cogs are easier to service and fix

I learned about reluctance motors a few months ago… has anybody tried to make a linear reluctance motor? Zero expensive magnets :)

While the second half of the video has some very relevant suggestions, I do feel that it is not necessarily adding credibility when you state outright that you prefer hand calculations in a video about doing less FEA and more hand calculations (conflict of interest, no?). An FE specialist is unlikely to suggest that hand calculations are a waste of time, on the other hand. I would imagine that what you pointed out for the hand calculations (i.e. that they take a lot of time in the beginning but become quicker over time and experience) apply equally to finite elements calculations, no? Especially since a finite element model can provide significantly more information relative to the time spent.

How would you do this without a lap weld. Sanitary design?

Thank you so much

Excellent Corey, Excellent !!! Thank you very much for your advice and competence !!!

Perfect 🎉

Good job 🎉

amazing!!

Hey Corey. You said TT would only have three inversions... so clearly you are being careful not to overshadow ArieForce One !

Mentored engineer, could you do a video covering hydraulic theory behind sizing a pilot to open check valve on a log splitter? Specifically selecting valve cracking pressure and pilot ratio? As well as hose sizing for a 22gpm pump?

Great video!! I was thinking it was a counterweight used to help tension the chain. Thanks for the explanation!

Same pumps are on these chinese excavators i wonder how hard it would be to change from a singke stage to a dual pump?

Thanks for posting this! I was about to do this on a tractor loader to allow the use of the original remote valves. Saved me from trouble!

I really liked this analogy, thank you for sharing

I don´t know where to start reviwing my hand calculation but is a must, I have to study all the procedure again, it's been a long time since I did this type of structural calculation

Great advice

I have 1s=10 3p=20 1r=50. When i did the equation r-s/p (p=3) i get a decimal. What am i doing wrong here what did i miss?

In the 1860s the limitations of cast iron were known yet Bouch to save money still used it in tension on all vital pier couplings and combined with appalling manufacturing was criminaly negligent

Much explaining with words but less animation. 😢

How did you do the launch? I have a backyard coaster I build in the Raleigh NC area with my girlfriends brother, and we want to add a launch instead of its lift hill

It should never have gotten this far and the fact that it did speaks extremely poorly of the safety of the entire park

Those airtime moments are super awesome

bro please get rid of that tree

That outerbank by the tree 💀

Hi Sir, Can i get 3 cylinders sycronizing

RMC elements on a backyard coaster 😭

On bro shi if a person tall enough they gonna hit that tree for sure

mine is calculated to zero.why?

You man’s the comment section neck hurt

Anyone else neck hurt
