  • To be precise, that’s a cogwheel. There are six cogs around the cogwheel in your image. The word “cog” refers specifically to the teeth around the wheel, not the wheel itself. The cogwheel may be colloquially called a cog, but it’s technically inaccurate; If you told a watchmaker that their watch was missing a single cog, it would have a very different meaning than if you told them it was missing a single cogwheel.






  • This is the worst way to go about doing it, because you should never assume a drawing is made to scale unless it is specifically marked as such. A protractor would be useless if the drawing isn’t to scale. Generally speaking, if a problem isn’t drawn to scale, it’s because all of the info you need to solve it is already present in the drawing. You don’t need to bust out the protractor to measure angles, because the angles can either be calculated from the available info, or aren’t needed in the first place.

    This is how it works in Germany. Lots of their water bottles are made of glass, and end up with textured/worn rings along the bottle; The rings are from where it goes through the recycling machines to get prepped for the next use. The rings mean the bottle has been reused a lot, and has gone through the machines enough to get slightly worn.






  • The worst part is that LiDAR isn’t even expensive anymore. Hell, my phone has LiDAR. He originally said that to justify the fact that they were dealing with a component shortage and he needed to keep shipping vehicles. So he simply shipped them without the LiDAR systems that he couldn’t get ahold of, and claimed it was because he didn’t need LiDAR.

    But now LiDAR is much more advanced and cheaper. But since he refused to admit it was because of a component shortage, adding LiDAR now would require Musk to publicly admit he was wrong. And we all know that will never happen.
