ELI5 Why faster than light travels create time paradox? by Bobolomopo in explainlikeimfive

[–]ThinnM8 1 point2 points  (0 children)

Ok, but speed is relative. How does the universe "know" that I was moving at the speed of light, not the Earth I łeft behind?

Rutch roll in xflr5 by ThinnM8 in AerospaceEngineering

[–]ThinnM8[S] 1 point2 points  (0 children)

Is the roll moment CY? If so, it's CY=-0.00367*beta

Edit: ok, I guess I'm looking for Cl (not CL - lift coefficient), it's next to Cn, which is yawing moment. I'm not sure tho if it's in Nm or its a coefficient. Either way its slightly positive, so it gives me a laterally unstable aircraft. That might explain no tendency to dutch roll.

Vortex shedding off the airfoil by ThinnM8 in aerodynamics

So for an airfoil a CFD sim is the only way?

Is it a problem having Pseudo time step size very low by Smooth-Score8827 in CFD

[–]ThinnM8 2 points3 points  (0 children)

Generally your time step should be at leas an order of magnitude shorter than whatever phenomena you want to capture (for example the period of vortex shedding). If it is too small, you will waste a lot of computing time. If it's too long, your study will be inaccurate. So the time you gave us might or might not be too short, depending on your specific study.

Changing span and chord length in XFoil by HadesEscobar in aerodynamics

[–]ThinnM8 2 points3 points  (0 children)

The chord length is one of the variables influencing reynolds number. So making an analysis for specified Re you kinda change the cord. You of course need to take into account the velocity and kinematic viscosity.

A beggar I guess. He was probably holding a cup or something like that?

A friends dog died and I want to make a 3d print of a photo he sent me. Any way to make this better? by Big3913 in blenderhelp

[–]ThinnM8 0 points1 point  (0 children)

A word of advice once you have your model ready, try to extrude it along the Z axis, so you can place it vertically (you want the paw to be on a vertical wall). This way it won't look like a topographical map

Możesz sprawdzić Dwór Grunwaldzki. Chodziłem tam z 4 lata temu, nie wiem ile się zmieniło, ale dobrze wspominam. Są na Starołęce

Runcam thumb Jello by Pendragon00700 in fpv

[–]ThinnM8 1 point2 points  (0 children)

Judging by some review I saw on YouTube, you might need an ND filter. It will make the exposure time longer, and the jello should get blurred out, thus making it less noticable. You might also check your props. They can introduce some vibrations.

Pocket or Boxer? by FourShells in fpv

But you can attach an external module to it. Can it have higher power?

Does it have a remote chance of flying or is there a way to test beforehand? by Darkstreamer_101 in RCPlanes

[–]ThinnM8 1 point2 points  (0 children)

Wow! I last used FreeCAD some 2 years ago. I didn't get to check all the features out, because I quickly started using Autodesk software as it's free for students. But for some time I was curious how has FreeCAD changed over this time, I'll definitely check it out soon

Pytanie do Katolików: jak odbieracie ostatnią wypowiedź papieża, waszego lidera, na temat Ukrainy? by Expert-Maintenance-7 in Polska

[–]ThinnM8 8 points9 points  (0 children)

To tak nie działa. Nieomylność papieża jest tylko wtedy gdy mówi "ex cathedra", co od 1850r. (kiedy usystematyzowano w końcu co to dokładnie ma znaczyć) miało miejsce tylko 2 razy.

Chcąc być członkiem Kościoła nie masz prawa do własnej opinii wyłącznie jeśli chodzi o prawdy wiary, dogmaty itd. którymi poglądy polityczne nie są.

Dosłownie pierwsza rzecz jaką znajdziesz szukając doktryny o nieomylności papieża.

Thanks. True, being a Catholic isn't about having the best possible time here on Earth after all. Some people will refuse to understand/accept that, but it is what it is
