  1. Aluminum alloy. The aluminum alloy structures are engineered for the stress they will bear, and they are inspected regularly. They should be retired before they fail.

  2. Nonsense. We are bimetral in the United States, where this channel is based. Units are equivalent. Jason is competent in both US and Metric units. If you are not, that's your limitation. By the way, the United States has never used Imperial units. The formal name is "U. S. Customary" units.

  3. ⁠​⁠ @logitech4873 — Some Europeans use "pound" (or a similar word) for half a kilo. That is close enough to understand Jason's use of the unit in this video. Anybody interested enough in mechanics to watch this channel is certainly capable of understanding what a pound is without difficulty. Resistance to it is just a matter of attitude. One thing I like about this channel is that the presenter is not dogmatic about units. He uses both U.S. and Metric units freely according to whichever suits his purpose, and even uses some unfamiliar units from time to time. That shows that he understands that units are arbitrary and equivalent. The physics is not in the units, it is in the relationship between things. Jason uses pounds here simply because that is how most people in the United States characterize the forces involved in towing. The truck makers generally publish specifications in dual units, so anyone who is challenged by English units can just refer to the Metric units. As for the need to know English units, I wonder how mechanically inclined Europeans refer to the square drive on their tools. Do they call them "the big one" (half-inch) and the "middle one" (three-eighths inch), or do they use the nearest (but inexact) mm equivalent?

  4. We have never used the Imperial System in the United States. We use U.S. Customary units and Metric units.

  5. Not many cars these days are built for towing, and pickups are a lot more comfortable than they once were.

  6. A lot of the hate directed toward Tesla is actually hatred of Musk.

  7. Jason is merely illustrating the principle with that simplified diagram, not giving you a plan for building a trailer. As he said.

  8. He isn't a hater. Tesla cultists are just hypersensitive.

  9. Just to make a joke. Have you ever watched this channel before?

  10. It isn't sold in Europe.

  13. He was joking.

  14. Boat motors used to have shear pins on the shaft. Don't they still do that?

  16. Jason often uses Metric units, but for this video I expect he uses pounds because that is commonly how the towing parameters are given in the USA. It's a trivial conversion. The engineering is in the analysis, not the units, anyway. Units are arbitrary.

  17. Jason has always taken this approach.

  18. As he said, he was just illustrating a principle.

  19. "Aluminum casting" says it all.

  20. A deli owner near me recently bought one. He picks up wholesale boxes of groceries with it. Why did he get that, you ask? Because he had been using a GMC pickup with the 6.2l engine. That's the one that self-destructs at low mileage. So many have failed that GM can't keep up with the demand for new engines. He couldn't wait the three months they needed to get one. I guess he was just disgusted with GM and wanted something completely different.

  21.  @joecooper1703 — No hatchback carries what any full size pickup carries. Anyway, I'm not defending his choice of trucks. I'm just reporting that the Cybertruck will carry a lot of groceries in wholesale sizes.

  22. His diagram is pedagogical, for illustrative purposes only. As he said, "simply to understand and to prove a point." What he want to convey is the principle of how the forces are transmitted to a hitch.

  23. There is another way to overload the hitch vertically that I don't think you mentioned, although you illustrated it at 17:57. If the connection has limited range of motion in the vertical plane along the longitudinal axis, and you exceed that range by driving over irregular terrain, the hitch will try to pick up the entire weight of the trailer. That is why trucks used off-road with trailers use a different type of hitch.

  24. The best use of the trailer hitch would be to tow a Generac, to keep the beast charged up. I wonder if you can drive it while charging.
