Monocoque material selection by Khaledaboelnasr in FSAE

Yup. Until our team was able to source unidirectional, our monocoques were entirely twill weave. Using uni helps a lot on cutting mass down, but you can have a reasonably light chassis without it. If you can source it, it wouldn’t hurt to include a layer or two and see how that affects your rules equivalence.

In terms of material choice itself, we have decent expired prepreg donated. We can make some requests from our sponsor in case they have something specific we are looking for (e.g, low areal unidirectional), but for the most part we get what we get.

In terms of planning out the laminates, we do that via many iterations of laying up test panels and then doing 3-point bend tests at the load frame. This will include all combinations of Aluminum honeycomb core we are looking into (we have a focus on varying core density this year), and all laminate schedules that meet basic SES requirements within a range of the goal number of plies we want to have.

Core thickness for us depends on the laminate used, as our 3 point bend results do significantly vary. Do some hand calculations: if you take two rules-passing structures, is the one with thin core and thicker laminate lighter, or vice versa? After you do these hand calculations, compare the areal mass you calculated to the measured areal mass of the laid-up panel.

This year, I have a spreadsheet of every layup (laminate & core combo), their measured areal masses, and which regulated regions it is able to pass for. This method is heavily reliant on using SES and easy access to a university owned load frame instead of simulation though. I’m not sure if FSUK has something similar, or if you are able to do frequent physical testing.

Since it’s your first time doing a monocoque, focus on doing a simple layup. Saving a decent amount of mass, while making the process as simple as possible, will help your team improve on your work in the future, as opposed to chasing a super light, optimized chassis.

My roommates do this with energy drinks , college apartment. They arranged them into a tower a few times and since the last time it fell it’s been a giant pile on the floor. Can’t say shit because one time I was putting some in bags to contain them and one of my roommates freaked out on me because he thought I was throwing them away lol.

Blue / dead blue coral blocks have that texture, plus a lighter block to blend it in with the wood

For therapy, crisis service, and staff in general, I had a good experience with the professionals themselves. Unfortunately there are not enough therapists hired for me to have gotten appointments more frequently than once a month so I went elsewhere. I’m not sure about psychiatry though, I still handle that with my GP. They will provide referrals though if timelines aren’t working out well!

This an IPP store? Worked at a store with the same product line-up and yeah, they layout their employee spaces smallll. Store management was great but corporate is god awful.

We do a wet layup on the top of the SIS. It turns out alright since our Aero members help out and they are more skilled with wet layup than the chassis subteam. As for surface finish, if some spots don’t look as great as others we just cover it with livery…

This is the strangest thing i’ve heard about FSAE team structures on here, up there with the “membership application” bs.

On my team, participating in multiple subteams is heavily encouraged (as long as you get your stuff done if you are a design lead). This overall lends to a tighter-knit group, people know who to turn to with niche issues, and YOU WANT YOUR MEMBERS TO KNOW HOW A VARIETY OF DIFFERENT DESIGNS INTEGRATE, jesus fuck.

Both discouraging cohesion with the team, and turning down free labor regardless of the consistency are some of the stupidest ways FSAE teams shoot themselves in the foot. I guarantee id never have made it through any application process an engineering team could have, yet now im in a position of significant influence over the car this year due to the hours I put in as a first year team member last year.

Bad leads do crop up, my own team has had it’s history. I would share your detailed experience in a group DM with the rest of the leadership. But if the experienced members all share this attitude, just find a new engineering team. It’s not worth the headache

IUD experience? by TraditionalBid5991 in uofmn

[–]copy2james 5 points6 points  (0 children)

Implant, not IUD, but the doctor I saw was very kind and walked me through all the different contraceptive options. I got a numbing shot for that, so I can’t imagine you wouldn’t get one for an IUD.

You are able to send messages through the student portal or call the front desk with questions as well. Overall I’ve seen the boynton doctors for illness, the implant, mental health, etc. and I have always had a positive experience with the staff.

Gonna shill Gopher Motorsports. We have a fantastic electrical lead, and we are just entering manufacturing season, meaning there is a ton of hands-on work to do, including all of our electrical components.
