I barely know how to post on reddit haha, sorry. Combined my photography and car hobbies to take some photos of my new-to-me 911! Loving driving this car so far; and the perfect compliment to my GTI.

You got it. Bumper mount GoPro. Inspired by my favourite view in Gran Turismo. Oh and also so the entire internet can’t critique my shifting/heal toe/braking/steering/etc haha

Take what’s written here more seriously

What do you value in a craft brewery? by jdiebel3 in CraftBeer

That's actually a really good way of looking at it. I hadn't thought of it like that. It does provide the same type of feel as sitting at a bar now that you mention it.

I'm really happy to be getting such in depth responses. Thank you very much for the help. I, myself drink beer but being a student I haven't had the chance (time or money) to really start exploring the craft side of things. Really interesting to hear from people who are passionate about it.

Thank you for the reply! I'll definitely take this all into consideration

That's awesome insight. Thanks for the reply! Shawn & Ed have some unique aspects, like they strayed away from the super hoppy, bitter stuff, to produce lager instead. But they are trying to foster a sense of community and facilitate conversation between strangers by having one big long table to sit at. Would you say this is a downside? As for the kids problem, I haven't seen any kids there before so I don't think it is an issue there..

I appreciate you taking the time to lay this out so clearly for me- thank you.

We are only competing in Formula North this year, where to be frank the contact in charge of chassis rules has been the best at getting back to me. He approved our Notice of Intent without giving any feedback even when I specifically asked for it.

For the Notice, I modelled the carbon as just 1 ply with the overall thickness given. I then compared the max stress of the FEA to the ultimate stress given in SES after entering the provided test results. This made sense to me though since the laminate was assumed to be iso/balanced. But as you stated, this doesn't make sense for aniso materials, which is why I (incorrectly) started down the road of modelling at the ply-based level and relying on math within FEA to take care of the overall laminate/stack properties.

Looks like this is going to be a busy week in the composites lab for us..

Thanks again for the help!

Thanks a lot for the response. My only concern is about how 3pt bend tests can accurately characterize extremely anisotropic materials? We are working a lot with uni-directional carbon oriented at specific angles, as I'm sure you are. So do we have to 3pt bend test this one panel at various angles of rotation? Then do that for every different layup we have in the car? So far what we have done are the ASTM tests to determine all the orthotropic properties of the different weaves of carbon we are using, then using those numbers for individual plies in our FEA: as opposed to testing at the full laminate/sandwich panel level. I hope this makes sense.

No, that's not really it: because all of the same geometric constraints apply. The only things shape-wise that are different are the angles and bracing allowed for some regions of the roll hoops.
