  • Okay yeah that's a little dumb. I could maybe see using WD-40 to free up a solenoid that was mechanically stuck but broken insulation says to me replace the part.

  • Hmm, that's interesting, I'm thinking like a pilot here but tip vortices increase in magnitude as AoA increasess, adding to adverse yaw of ailerons. I figured birds handled yaw control through wing sweep, kind of like how a weight shift trike does.

  • Sooooo WD stands for Water Displacer. It isn't a lubricant, it's more of a cleaning agent. It was originally developed to keep Atlas rockets from rusting. WD-40 might fix an electrical component by floating off any water-based electrolyte that might be shorting something out.

  • So, guys don't care about a girls income that much. There's an entire subculture of men that prefers or demands being the sole breadwinner of their families. I'm going to say the word "tradwife" and consider my point made.

    Guys will go for an unemployed girl. Pretty and nice will get you a man. Which weren't you?

    Mind you, when I was in college I tutored freshman chemistry for an hour on Wednesdays and made more than $25/week at it; how delusional was your business plan?

  • No it's more that physics is a fickle bitch.

    Those spirals are called tip vortices. They occur because there is relatively high pressure under the wing and relatively low pressure above. At the wing tip, that higher pressure air wants to roll up over the wing tip to get to that low pressure area, which is what sets that spiral in motion. Any airfoil that is creating lift will have a vortex at its tip. Wings, tail surfaces, propeller blades, rotor blades, you name it. The higher the angle of attack, the more significant the tip vortex.

    Have you ever seen a jet airplane that has fuel tanks out at the wing tips? Most of the reason they're there is to reduce tip vortices and thus reduce drag. The additional fuel capacity is a minor byproduct. You might notice most newer airliners feature winglets; the wing tips are turned up. That's not for additional yaw stabilty, those are there to reduce tip vortices, decrease drag and decrease fuel consumption.

    Tip vortices are the main factor in wake turbulence, which is an entire class session in flight school. All a tower controller will say to you is "caution wake turbulence." And they're right. It's the pilot's job to know what to do about it, because trailing behind and below the wing tip of every airplane is an invisible sideways tornado you just have to know is there so you don't get thrown onto your Cessna's roof when landing behind a Boeing.

  • The bird flies despite the spirals, not because of them.

  • Does a PBJ have a defined "up" side?

    Jump

  • Correctly made, a PB&J should be symmetrical. A layer of peanut butter on each slice of bread with jelly in between, so the jelly doesn't sog up the bread, especially if the sandwich is to be stored for awhile as in a packed lunch.

  • Technically, it should be possible to built a pot that uses the heat from the stove to stir it's ingredients.

  • I'm an above average candidate for the Connecticut Yankee In King Arthur's Court scenario. My hand isn't a chainsaw and my boomstick is a pump action Ithaca not a double-barrel Remington, but also I could make a radio more or less from scratch. You can make a point contact diode out of rusty iron and graphite.

  • What are your favorite fun facts about animals?

    Jump

  • Humpback whales are able to navigate exceptionally well and I don't think science knows how.

    Humpback whales travel by picking a direction and traveling in that direction. They can maintain a true course to within a degree of accuracy for hundreds of miles regardless of location on the planet, ocean currents, magnetic variation, day or night, though open empty ocean.

    I know how to do that, but I need stuff the whales don't have like visual reference to a solid surface, accurate charts, radio-based navaids, winds aloft forecasts, and/or gyroscopic instruments. Most of the time, most creatures either navigate by landmarks, some are able to navigate magnetically, some can home, ie they can sense a destination and point their noses at it and go that way, as forces such as winds, ocean currents, Coriolis force etc. push them off course they steer to keep the destination dead ahead, tracing a half-teardrop course.

    But humpbacks can pick a direction and go perfectly straight. Somehow.
