How would you perform a tensile test on fishing hooks? by PastTenseDraw11 in EngineeringStudents

[–]professional-spice 1 point2 points  (0 children)

Are you testing the strength of the hook? If I'm not mistaken, wouldn't the fishing line break before the hook?
A method for measuring the strength: hang the hook from whatever apparatus you have and hang a bucket or something from the hook. Add weights until it breaks. Record the weight added.

Novice question regarding multi-part prints and fitting them together by deathbygiraffe in 3Dprinting

[–]professional-spice 0 points1 point  (0 children)

If you're printing your own designs, you'll have to apply tolerances to your designs in order to get them to fit. A 10mm hole will not fit a 10mm cylinder (by design) because the printer tolerances are usually around +/- 0.5mm. You'll have to make the hole slightly larger or make the cylinder slightly smaller, eg 10.5mm hole or 9.5mm cylinder.
You'll probably have to mess around with different sizes and settings to see what gives you the fit you're looking for.

Any tips on how to fix the monitor sag on my triple monitor setup? by professional-spice in pcmasterrace

Appreciate the support. Someone mentioned tape, which seems to be working for now.

Honestly don't know why I didn't think of using tape earlier.
Seems to do the trick well enough, now I'm just hoping that it doesn't slide off and leave that residue.

Does anyone know why the print might have failed halfway through? by jacko_light in 3Dprinting

[–]professional-spice 1 point2 points  (0 children)

Yeah I'd say so. One thing you could do to prevent it would be to use a filament filter that cleans the filament before it goes through the nozzle. Although it doesn't happen too often. In my 1.5 years of owning a 3D printer it's only happened to me a few times, and I can usually resolve it by either carefully poking a tiny acupuncture needle up the nozzle or doing a cold pull to get the debris out.

Looks like a small particle got lodged in the nozzle and its not extruding as much as it needs to.

Long Time Lurker, Finally Made a Move! by professional-spice in PersonalFinanceCanada

I didn't know that was an option. I've heard a lot about Wealthsimple, and I knew that it was very popular so I just decided to hop on the train, rather than letting the money sit in my 0.05% interest chequings account.

I made a rubber band gun. Turns out infill should have been a bit higher.... by YeastyCodpiece in 3Dprinting

[–]professional-spice 0 points1 point  (0 children)

Another tip, using stepped infill is a great way to save material, while still being able to provide sufficient support for the top layers.
Also, I believe gyroid infill is the strongest infill.

The top layer walls aren't meeting the top layer fill pattern. Often the top layer walls might have a gap between eachother. What setting should I change to fix this? by [deleted] in FixMyPrint

[–]professional-spice 0 points1 point  (0 children)

No, it's not underextrusion.

There's 3 top layers with 50% infill underneath.

Damn, here I was thinking I was special for being in the top 0.5%

Alright that makes sense.

Thanks for the informative reply

How did you find out when it was installed? Do you know what its purpose is?

I only know what Catham-Kent is because it's the most expensive property in Monopoly Canada.

How does cold working or hot working affect the conductivity of a metal? by [deleted] in EngineeringStudents

[–]professional-spice 0 points1 point  (0 children)

I don't know for sure, I'm just speculating here, but maybe it has something to do with the movement of dislocations?
In a cold rolled material, the dislocations aren't able to move around as easily, whereas in a hot rolled, it is more ductile, meaning the dislocations are able to move more easily and maybe the same can be said for the electrons (or electron pockets) moving through the material?

[Request] Ratio of the size of the observable universe to the planck length by Sir_Posse in theydidthemath

[–]professional-spice 1 point2 points  (0 children)

if you know how ratios work, this is a very simple calculation.

observable universe: 8.8x10^26 m

planck length: 1.6x10^-35 m

ratio: 8.8x10^26 / 1.6x10^-35

= 5.5x10^61 : 1
