Science & Engineering Shit

I can tell you right now that this guy knows the difference between the median and the mean.

Not to go all gear nerd here, but this guy is overstating this a bit. Involute gears have a lot of advantages and are the most common, but one of their disadvantages is that they create more friction and wear faster than the other main type, cycloidal gears. Watches use cycloidal gears precisely because they don’t have as much friction and don’t wear out as fast as involute gears. But something tells me that the issue here isn’t the gear type, but rather the fact that it’s a freakin’ children’s toy meant to illustrate the basic concept of rotational motion, not a Swiss timepiece, and that making a “proper” involute gear to meet this guy’s exacting standards would have bankrupted the toy company.

Looks like Big Gear has their new spokesman.

Magnets would have completely replaced gears by now if it weren’t for the Big Gear lobby.

You kids today and your magnets. I’m more of a sprocket and chain guy. Sort of analog in a digital world.

And the fact that gears still work underwater.

That’s just a matter of a pinion.

Well, certainly not underwater.

This is actually more about shit engineering than engineering shit.

ETA: Make sure you have the volume up (unless at work or around children).

I had to replace the starter on my mother’s Mercury Comet when I was in college, and I swear to God that when they built the car they started with the starter on a little pedestal and then built the rest of the car around it.

I drive a Genesis and a few years ago there was a problem with I want to say the oil pressure sensor. The boys over in Seoul seem to have had the same idea, building the car around that pertiklur gauge. The shop owner was telling me it would be a quick fix as he opened the labor time estimator app they all use nowadays. When it spit out the estimated labor charge his eyes got huge and he seemed to levitate. I guess I’d rather that than demonic laughter.

Anyway, my oil pressure sensor works great now.

We had a 2013 Ford Escape and you couldn’t even jump the battery without taking off half of the right side of the engine.

The battery of my car is in the trunk. I won’t tell you how long I spent looking for it before I found it.

Until proven otherwise my perspective and advice to everyone is pick a body style then just buy the goddamn Toyota/Lexus version of it. Hybrid if possible—the hybrid system and ecvt (which is not in any sense mechanically related to a traditional cvt, I hate that they called it something similar) age exceptionally well and take a lot of strain off other mechanical components.

The two major exceptions are the Tundra (thanks to all the recent bullshit with the engines) and the bz4x, which I don’t think anyone buys anyway. I’d also give the new Land Cruiser a few years to see how the turbo turns out, but I don’t know of any actual problems with it.

I’ve had many cars, then I bought a Toyota. I have 220,000 miles on my 2004 Tundra and have never had an issue other a left front ball joint replacement. I don’t drive it much anymore, just when I need a pickup. I hope to have that many miles on my 2023 4Runner someday.
