On a MacPherson strut, the strut is acting both as a spring/damper and as the upper suspension arm. The Miata's setup is a coilover that happens to look like a strut.

The upper A arm allows the camber curve to stay nice through-out the travel of the suspension vs the strut. This might be some good reading on the subject: http://blogs.youwheel.com/2014/06/11/automobile-suspension-design-101-part-i-what-is-a-suspension/ https://www.me.utexas.edu/~longoria/VSDC/07_vertical_dynamics_and_ride/07_1a_Milliken_Milliken_Chapter17.pdf fridge corn posted:Lol those two suspension setups are nothing alike Shuddup you, we're trying to help them learn.

Simply put, when you corner, the outside suspension compresses and the body rolls over. With a strut suspension, your camber basically doesn't change when this happens and so you wind up using the outside edge of the tread and sidewall, which is not good for wear. To make up for that, you need a bunch of negative camber so the full tread is flat on the ground in a corner. But that reduces grip while braking and leads to uneven tire temps and wear. A double wishbone, on the other hand, can have much more camber gain under compression so that as you corner, the tire stays perpendicular to the ground. The other thing is that a strut has to take up a ton of side-loading, which is not ideal for the damper itself. With wishbones, the arms are handling all that and allow the shock to work just as a shock.

He's really the Steve Jobs of the market he is tackling (vertical business integration, tight control of supply/demand, locked down access, etc). That's my point; it's very much like the Apple thing contrary to what Fridge Corn was saying - I'm seeing it as almost exactly like Apple repackaging other people's R&D. Which, I mean, is fine, but I'm not going to bend over applauding it as revolutionary. puberty worked me over posted:Do you have some whitepapers on this? Really curious what makes the miata stock suspension setup so much better than everything else. Also you and I must consider struts to be two different things because the stock BRZ suspension doesn't look a whole lot different than the stock Miata suspension. Are you stating the fact that the bottom of the front struts are held in with two bolts vs the miata's one that makes a huge difference? Oh boy. Some people already covered the basics, camber gain. That's a good and important thing. But the complicated version is more important. See, there's a concept called roll center - basically it's an imaginary point that sideways force works through. And the concept is important for a variety of reasons, but among them is apparent roll stiffness. See, the distance between the roll center and the center of gravity is the lever arm to determine how much force the body of the car is under to make it roll. On double wishbone suspensions like the Miata, you can set up the roll center to move with the body - under body movement, the lever arm stays the same. On strut suspensions, as the front end of the car goes down, the roll center always drops faster than the CG. Why works out to geometry, but the crux of the matter is that because that lever arm changes, you have it where one end or the other doing more work twisting the car varies with where the nose of the car is... which means that it may vary from under to oversteer depending on whether you're braking, accelerating, or often depending on body roll. Why *that* is important, is that it means that to keep the suspension from doing unpredictable things, you have to stiffen the poo poo out of strut suspensions, which hurts grip past a point. With wishbones you can let things be softer and the suspension can move around because it's not doing bad things. Double wishbones on all 4 corners (or stuff that works out to it) is the layout used by every single on-road purpose built race car since the 60s, but usually isn't adopted by cheap production cars because it has packaging implications and sometimes costs more.

Yu-Gi-Ho! posted:That's a proper tree though. Nice, full, plump. Mine is the cheapest Well, I'm actually pretty happy with the way these turned out. I thought they'd be a bit too white at first, but once I unwound them I found that they actually look pretty good:  These are actually pretty decent, a little bit of flicker, but you can only really tell when you're like right up next to them. Also my first, and probably last time using a real tree. Not quite as stiff as I'm used to, but it worked. Hopefully over the summer Balsam Hill will have a good sale and I can pick up a really good fake one to last me the next 15 years or so.

6 foot (really, it's more like 5 ft once you remove the stand and the little twig at the top) I could find. It really looks like a sad little Charlie Brown tree until you fill it in with lights and ornaments. And I made the mistake of going with mostly dark ornaments; it looks like there's hardly any on it because of that. I'll go with a different tree next year.. one that's a bit fuller, one that's also maybe a bit... different. I saw some black ones that were pretty awesome, but they were only pre-lit.

InitialDave posted:Is it worth it? Or better to bid it a fond gently caress-off and get something else? Quandary however: Option 1: buy cheap inefficient car for wife i.e. Auto petrol v70. Cheap to buy, her low mileage won't harm it, can still be used for family holidays Option 2: buy a hybrid i.e. Gen 2 prius under 100k miles, again plus points as above except we need to tow a 1000lb trailer for family holidays, can't legally tow with a gen 2 prius Option 3: buy me a diesel v70 or similar, my higher miles will be fine on it, good family car for holidays, wife has to have my panda. Option 4 of buy a cheap stop-gap hatchback and replace the gearbox myself has been rejected already, because gently caress that. Option 5 paying the garage to tow it away and replace it probably costs more than buying a better car. Yay Christmas finances.

If I was on a faster tier I'd probably notice. 10 hours since he left, modem has half a million correctable errors, and over 1M uncorrectable. I'm used to a handful a day.

Powershift posted:How many eyes do you have left. Two. Who cares about that when I have damaged a usable battery? It's definitely not the best battery but it has been usable. The other maintenance free battery I popped the top off today had cell covers. I topped it up. It needed some because I made a mistake yesterday. Had the stupid battery on charging for maybe four hours. It's a poo poo battery that I just use for stuff around the yard. It didn't really want to take much current. Over the course of the day the current it was taking was going up. I went to have a shower, and when I came back out there was steam shooting out the vent like a kettle and the charge current was sitting on maybe 30A. Whoops! Today I also got stuck in a town over the border. Niva wouldn't crank. For the third time in my life I had to call roadside assistance. Started instantly with jumper leads. Stalled it in the driveway when I got home. Started without an issue. I really need a couple of new batteries for the cars but this time of year is very bad for finances. Have to ride it out.

Liquid Communism posted:Useless fucker probably has no idea, just knows barely enough about coax to get TV signal to kinda work. Pretty much. He said the levels my modem was reporting were useless, and his handheld device was the only thing he could go by. The previous tech said the handheld device (same one the contractor had) was more accurate than what the modem was reporting, in that it could report real-time instead of waiting for me to refresh, but was much more receptive to my input. I'm already noticing issues with packet loss, particularly with VoIP and Skype. Skype is drat near unusable. loving dipshit that was out here was ramming sheet metal screws into drywall too, and was confused why they kept pulling out.  Didn't even apologize about the multiple holes he left from screws that pulled out. The upside is I got a ~$50 cable amp out of this; it's the 1 port version of the amp I put in my parents house. It's a very good amp, but he slapped a bandaid on a much bigger issue because he wanted to move on to the next stop. I knew he was way ahead of schedule when he woke me up at 11:30 asking if I was home (my appointment was 3-4pm, I don't usually wake up until 2pm), which instantly tipped me off to the contractor aspect (they get paid by the job, so the more they knock out per day, the more they make). And I fully intend to take that amp with me when I move; it's not marked as TWC/Spectrum property, and he asked me to throw the box away for him. No inventory number on the box or anything, and his shirt had the name of a local contractor. Didn't sign any paperwork, and it's not something a cable tech would normally install unless there was no other way to fix a signal issue.I've stayed in touch with my landlord about everything.. they never cleared any work with her like they were supposed to. I sent her the same picture, she's understandably pissed off about the poo poo work. He also managed to rip the drywall anchors out of the wall that were holding the wall plate to the wall, so it's just kinda held there by the tension from the cables. Nothing that an old work bracket can't fix (and that's how it should have been done to begin with, years ago, instead of just jamming the wall plate into the wall with tiny anchors). I'll throw a trim ring behind it tomorrow to keep the drywall from getting hosed up further, then call back and bitch about the packet loss. e: also, I still have 1 working cable jack.. out of 6. I was hoping to move the modem and router to my bedroom, damnit. randomidiot fucked around with this message at 09:48 on Dec 5, 2017 |

stump posted:My old man managed to do that with a hammer and fencing staple. Nailed himself to a fence half way up a mountain, working by himself trying to get a fence finished before Christmas. Of course he threw the hammer away out of reach as soon as he done it, so he couldn’t pull the nail out. Guy I used to work with in Parks was a chippy in a former life and was building a house. He was framing up a room and the normal procedure is you build the wall frame on the ground, stand it up, bolt it down and build the next wall and so on. He was on wall 4, it was getting close to lunch time so he sent the apprentice down the road to get lunch. 2 mins after apprentice is gone, he nails himself to the frame with the paslode. Goes for hammer- Hammer is diagonally opposite the frame to him where he was knocking something to square it up. This was back before mobile phones, so cant call apprentice to help. Cant slide wall frame around to get to hammer because he's got the other three frames already up. So he got to stand there hunched over for 25 mins waiting for the apprentice to get back so he could get the hammer and get the nail out.

An EV that is actually incredibly compelling with growing infrastructure of fast charging so you can drive it coast to coast like a normal ICE powered car. The EV itself might not be revolutionalry but the real revolution is that Tesla have solved a poo poo load of the questions we all had 10 years ago like the supercharger network that has proven EV's genuinely viable and desireable day to day. If I told you ten years ago you would have EV's that can beat the poo poo out of suprcars, that dont have range anxiety, that are in every way the equal or better of ICE, you wold have laughed. Theres your revolution because no one is laughing now. Even right now, if you had told me that a EV semi could work a year ago I would have laughed you out the door. I'm still dubious but..... Tesla just unveiled one. That even as a working concept is revolutionary as gently caress.
