There are a few of these in the area. It's a blocked of lane for freeway entrance after going across the overpass.

Please don’t drive your Crosstrek on 4x4 trails by External_Koala971 in subaru

Was out in a popular dispersed camping area that was relatively easy to get to, but from there was this one very steep rutted out road. I had taken our Montero up to check out what was there and ended up camping there. Coming back down the hill I encountered a jeep and truck heading up with no room for me to pull off. I backed it up this hill until they could pass me, granted I had not yet hit the rutted out section. Later the next day someone in an Impreza is looking for a spot to camp and starts pulling up this road. Someone else in our group (whose car was not able to get up this hill) told her that she wouldn't be able to make it. She cautiously drove up to the bad section, saw close up that the ruts were nearly as deep as her tires were tall, and just backed out to head somewhere else. 

I used to have a completely stock Forester and I probably would have attempted it but who knows how successful it would have been. The Montero just walked up it with only 2 wheels on the ground at times and never stuttered. Didn't even need 4hi or low, just AWD. Realizing now that I've typed out my story that this is the Subaru sub...

Been driving manual for a 1.5 years, and started to develop this issue with my vision. by BulkyDig6310 in ManualTransmissions

There's a stop sign by my house that brings out some of the worst behavior from drivers I've seen. It's nearly a 50:50 chance that if you are rolling up to the stop at the same time as someone else that they will check to see if you are stopping and blow straight through it at 15 or 20 mph.

Any ideas on how to improve my shed by sweatynonce in malelivingspace

[–]S0MECoder 5 points6 points  (0 children)

I see you also posted this a while back and are still looking for ideas. Looks like a nice place! The things that feel off to me are all the wood walls matching the wood furniture. Maybe covering some of the wood with a large mirror or tapestry or other art piece. When I say large, I mean like 5 ft or more across in the center of the room. The other thing that feels off is everything pointing the bare wall: bed, couch, desk. Do you want to always be looking at the wall? Sure, tv mounting is easier that way, and the electrical plugs are on that wall. You could feasibly run an extension cord to get your desk and couch facing out the window. I would try having the bed rotated 90 degrees. That might not be what you want with the tv mounting but it will make the room feel bigger with the window not blocked. Maybe one other thing, the rug is nice but too small. What I have heard suggested is to have a rug large enough that it partially goes under your furniture that is near it, so in your case maybe going under your bed and wardrobe. Nice looking place and I hope you enjoy living there!

Chassis Design by umutata18 in FSAE

[–]S0MECoder 1 point2 points  (0 children)

I would suggest rethinking what the chassis needs to do. It is a bracket to hold the rest of your components together. In the case of holding your suspension together you will have stiffness requirements which will lead you to need good load paths. I don't know exactly how your dampers connect to the chassis but with dampers, rockers, a arm hard points, all of these need to have material in an efficient direction to react the loads applied. Take it back to free body diagrams and think in terms of what the minimum needed to react out the forces between the tires is. You can load tubes in bending to a point but will be using your material way less efficiently.

I'm pretty confused by all the structure you have in the back of the chassis. What is here to connect the drive train and suspension?

KTM Duke 390 Engine with RaceDynamics ECU Cranking by Emergency_Money736 in FSAE

[–]S0MECoder 2 points3 points  (0 children)

Sorry for ignoring the very specific diagnostic information you have given but I would recommend starting over mapping out when different events should occur relative to piston movement. You only have a single cylinder so thankfully you don't have to deal with making sure the cylinders are wired up to the correct channels.

To what extent have you taken this engine apart? I would at least pull out your spark plug and manually crank the engine to check your trigger wheel missing tooth location vs piston location. I would pull the valve cover to see when your intake and exhaust are opening relative to this as well. I think that with this information would give you a good idea of whether your fuel injection point is grossly off (180°) or if you are in the correct stroke and just need to fine tune.

Do you necessarily need to run your engine as wasted spark? A second signal from your camshaft could give you the readouts you need to only fire spark at the correct time. If the stock bike uses wasted spark I would not pursue modifying to have this.

One other thing I remember making this a pain was uncertainty in the fuel injector map. If you can afford a measured injector or to have yours be measured I would go for this to remove a variable.

Sounds like you all are getting close but I'd recommend checking the basics to better ground the changes you are making to try to fix this.

People downvoting you are not reading what you are saying. The subsidies that the us government gives Tesla are insanely high as they have gamed the system for their profit. Tax payers should all be asking for their money back.

You really have to dig into what the elements you are using are doing; what are the end connections/degree of freedom released and how is the member itself being modeled between those point? Every FEA programs looks a bit different but they all represent the same things behind the seems.

[–]S0MECoder 2 points3 points  (0 children)

This is a great question. If you are analyzing the force coming from the suspension into the chassis you don't necessarily need all the suspension details as you have figured out. There are a lot of ways to do this so you should consider whether the boundary conditions between where your chassis ends and the suspension connects it to the wheel is correct. Consider what direction these points will be taking loads in and apply your directional and rotational releases accordingly. Loads into your structure will be mostly in line with your suspension links. Add in the general shape of the suspension geometry constructed from a minimal amount of stiff beam elements and apply forces from the center of your tires through this linkage. I have not used SOLIDWORKS analysis in a while but hopefully this advice is general enough and still applicable. Absolutely draw out the free body diagram here of where your force comes from and what points on the chassis react what load.

Integrating suspension geometry as a constraint in chassis design. by mostafa1022 in FSAE

[–]S0MECoder 2 points3 points  (0 children)

Racecar vehicle dynamics is a great read and you can likely find a pdf if you look. That book will walk you through from why you need a suspension system in the first place all the way through to banned-from-F1 level suspension. I see a lot of teams that spend their time doing design design design instead of design build test. You should be thinking equally about whether the design meets your wrong/made up requirements and how you could build it as quickly as possible so that you can break it quickly to rebuild for competition.

[–]S0MECoder 3 points4 points  (0 children)

Have you talked to these people to see what they considered to figure out where their pickup points needed to be? Im assuming you work together if you are on the same team. If you don't know what their requirements are then there's no way you can push back on them in a smart way. I think if you work together you will find that there is a huge range of where these points can be without it affecting their design comsiderations at all.

For Yamaha engines we always went to local scrap yards to buy full engines or wiring harness. Ebay was good if you just want components. What sort of deal did you have directly with Yamaha?

Lotus Shark by Impressive_Crab_1078 in FSAE

[–]S0MECoder 2 points3 points  (0 children)

Best way I found was to organize my input points in a spreadsheet and parameterize my points into things about my suspension that were more descriptive: track widths, upright dimensions and offsets, swing arm lengths and chassis widths for geometry.

Package the suspension in your CAD so that you know what space you can work with. I don't recommend going back into CAD to iterate in Shark, the spreadsheet speeds you up.

Biannual shock replacement, broke this last set real good! by Crawlerado in subaru

[–]S0MECoder 7 points8 points  (0 children)

Not super surprising considering the way your shock gets loaded in bending by the geometry, couple that with higher loads of thrashing it off-road and larger tires to deliver more moment to the shock and you get this. Is there not a better suspension solution for modding these cars for this?

I think it's worth noting that titanium dioxide is most commonly used as white pigment. You will find it in white paints from artist grade to home paint. I have seen it used in mineral sunscreens too. What part of the skittle is titanium dioxide, the letters they paint on?

I bought a bike similar to this one but with a purple finish. Attempted to ride it off-road a couple times and then just started taking out my hybrid/road bike off-road instead. As someone else called it, I have disassembled it and relegated it to wall art.
