Video Toolbox Lid Calculations

[@jaxnaturals]

I thought this would have been easier. Now my brain hurts. Great explanation and will come back to this when my brain is less cluttered and can absorb this information

[@GLHerzberg]

Very glad you produced this valuable video. It provides a thorough explanation of the trigonometry and calculations behind the analysis without divulging too much info as to give away the process yet all the necessary info is there. Ya, just gotta pay attention! I think that creating the spreadsheet is left as an exercise for the student to enhance their comprehension. Title typo in video at key-frame 0:00 - missing 2nd L in CALCUATION.

I built this spreadsheet based on his description of each triangle. It seems to work but difficult to determine if I have any errors. It would have been very useful to see the real life results in the video to see if my spreadsheet works correctly.

[@philwoodward8235]

That was an amazing tutorial thanks. I would really appreciate a copy of the spreadsheet.

[@itaist]

thanks a lot! can you share your spreadsheet?

[@stallion63m35]

Conversely,the brackets can be reversed. The curved one on the lid and triangular one on the inside of the box.This way the lid will snap shut keeping the lid fully closed and allow opening normally when it's opened by hand.

Real example of applied Mechanics 🙏🙏🙏🙏😁😁😁

[@mjones2431]

Any way I could get a copy of the spreadsheet?

[@cowboys168]

It is really good for me. Noted where I understood and you correct me in advance after watching the video. Could you share the spread-sheet to me? Thank you so much.

[@TimWynnAlabamaRollTide]

The Spreadsheet share would be nice so I don't have to re-create. Thanks in advance.

[@wayneeaston8287]

@Aaron please could you share your spreadsheet. It would be so helpful as a reference. I would really appreciate it. Thank you.

[@kinglost9523]

May have the excel sheet for my use please?

[@bradhall7155]

All my life I've wondered, "why did we learn triganometry in school, I'll never use this in the real world"? Who'd have thought I'd need it to keep my toolbox lid up?? Now I wished I'd listened more in class.....

[@giandomenicopriore5412]

hi, could you share this useful tool? Thanks in advance

[@SharathShetty-p8i]

Thank you very much for detailed video. Please upload the excel sheet.

[@JetScreamer_YT]

If I turned this upside down, would it work with a murphy bed?

[@davidsassoon4657]

Great video, thanks!

[@ElMakk_Med]

thank you for your efforts, i know you have your own reasons to hide the results...but it would've been better if you could show how it's done closely,

[@dalecaswell4793]

@Aaron is this spreadsheet something you could share?

[@the_natrix9959]

I have a 7 point hinge. The hinge point moves/floats elliptically as the arms lift, kind of like a scissor lift. How can I calculate this?

[@danba1769]

Is the excel sheet posted?

[@kamilwojcik7479]

what about friction? :)

[@the_natrix9959]

Are you willing to sell this spreadsheet?🙃

[@undeadfury55]

Why isn’t the excel document in the description? Does it not work?

[@Kirbythediver]

These are good maths.

[@SD-nj1cy]

I actually need this in the real world. i just bought a tool box and it only opens 70-80 degrees. i want it to open 90 degrees. I have one pivot point i cant move and one i can. is there a resource i can leverage to just tell me how long and strong a gas strut i need to use? i stink at math

[@truoghv]

Can u share speadsheet ? thank a lot

[@takundamacheka5357]

Love this

[@gunaselansadanantham867]

you are smart.

+Aaron Schellenberg. Viewers!!! If you are watching this video, do not use this method!!! If Aaron can't show the working out it doesn't work. AVOID!!!! The lid will fall on your head or your child will loose a finger!!!! AVOID!!!

[@Itsmellsfishy]

Are you serious? His working out is the entire video. If you cant do force analysis, dont attempt this.

[@yankos_]

@@Itsmellsfishy There is no working out shown anywhere in this video, just theory, to the extent where a spreadsheet is shown and this is also redacted, not showing results. Further, the formula bar is also redacted, not showing formula used. Why? I assume, that he has no confidence in his own calculations and hence there is not toolbox video. In my world as a mechanical engineer, and in the past as a applications engineer, I can do all the calculation for a design. At the end of the day the manufacturer/supplier of the component, will certify a design with an applied product, and take responsibility of the function of the assembly, allowing for real world variability, not pythagoras and spreadsheets.

[@Itsmellsfishy]

Yes he is just using pythagoras for simple geometry, but if youre a practicing engineer, it wouldnt take long to get the numbers he has hidden. Is there a flaw in his logic I am missing?

[@stallion63m35]

@@yankos_ "the function of the assembly,allowing for real world variability" That's what really matters! Not theoretical jargon.

[@andremartinho913]

Maybe you would be kind enough to share a spreadsheet with your calculations, given the same 16lbf lid weight, same McMaster-Carr brackets and the same gas spring?

[@danba1769]

How does this change if instead of trying to open a toolbox lid, I am trying to open a garage door completely out? Running into issues with triangle 2.
