2024 Canadian Grand Prix - [QUALIFYING] discussion thread ⏱️
  • There has always been a pretty large gap between Perez and Max in terms of performance. It's been speculated that it is more a matter of the competition's cars getting faster than Perez's performance declining. They have found a way to catch up with Red Bull car and only Max's skill is keeping them ahead.

  • Have you ever been to a movie so terrible that you saw people leaving the theater? Which one was it?
  • Both reading and watching The Shining really helped me appreciate what Flannigan pulled off in making Dr. Sleep. He kept all the lore and nostalgia of Kubrick's movie and also found a way to put back most of the King material that Kubrick had abandoned.

  • How come running hard (especially when out of shape) makes your lungs feel like they are on fire?
  • Acid buildup in muscle tissue. Here is an article that explains what is happening:

    Esit: I originally said that your.muscles are creating waste chemicals quicker than your bloodstream can handle causing those bad chemicals build up locally. While this is true in a broader sense, I think it is more nuanced that that. Reading the article should give a better explaination

  • Can I hang kitchen cabinet on my subconstruction I built?
  • We use three horizontal strips of thin flat stock metal attached to the studs with truss head screws before sheetrock to provide solid blocking at top and bottom of upper cabinets and also at top of base cabinets. The stock can be 20 or 22 ga. And 6" wide. You still may want to catch studs as best you can. I posted a picture showing the two strips that hold the upper cabinets. I'm not sure what the metric equivalent to gauge would be but you guys probably have something similar.

  • DC Theory: negative voltage
  • And a quick followup:

    If the ground was moved to the T3 junction than the battery's negative terminal would be common to ground and the voltages values across all loads would go back to being positive in regards to the battery's negative terminal (T1 = 1000V, T2 = 333V, T3 = 0V) ?

  • DC Theory: negative voltage

    I'm trying to understand what's happening in this circuit:

    I------------------T1 (+333V) I I I R1(10K) (pos) I 1000V I------------gnd (0V) (neg) I I R2(10K) I I I IT2(-333V) I I I R3(10K) I I I-----------------IT3 (-666.7V)

    I am learning basic DC theory from reading and sometimes I come across something I'd like to ask a question about, so:

    1. In the above circuit, without the ground, the voltage across all components would begin at 10V and finish at 0V. By adding a ground, I'm basically saying "here is 0V" and everything gets redefined in reference to that point and I end up with a 10 volt circuit with +3.33 as it's highest voltage and -6.667 as it's lowest.

    2. The electrons could care less, they still flow from the anode to the cathode of the battery under normal conditions, going from the highest potential to the lowest.

    3. This example was only used to demonstrate voltage dividers. It revolved around worker protection present in aluminum processing. Each machine is in series and mobile grounds are used nearest the machine a worker is using. I assume that this allows the worker to have the least exposure to electrical shock as they are also at ground potential?

    I actually think working though these questions has cleared everything up, but please, comment on anything I got wrong.

    Also, sorry about the crappy drawing, the autowrap in this editor really made things tough to format

    Thanks!
