Right?

Yes, if you have 2 sheets for the part and assembly.

If you had just the assembly sheet (with the battery under "materials" and not "parts") then there would only be 1 assembly number and no part numbers associated with it.

This is just how I did it, from my interpretations of the intent of the rules. I really don't know how it is going to be judged, though.

Mr. Riley,

My team has many mounting plates of varying size, shape, and personality. All were made with a plasma cutter. Do I need to cost the cutting process separately for each plate, or can I add up the total amount cut and show it all as one line item?

Thanks,
Jeff Freeman

P.s. I submitted the FCA bug report earlier in the week and included a few questions of my own. I've yet to receive a response. Should I post them here?

Mr Riley,

IO have have read that the European events won't use the cost database application. I wanted to know if anyway the materials table will be updated, so if we can still send AIR Form

Thank you very much

Does anybody know if and how to move assemblys from one system to another in the Cost Event Application?

For what it's worth, this is also my interpretation and how I did it as well.

Hi!

We're a bit confused... why does the "Starter Button" needs to be costed as a separate assembly? (Appendix C3)?

It's only a simple button...?

Thanks
Alex



Thanks for help

Alex

Hi again,

in what assembly do we have to cost the sensors?

Thanks
Alex

I put them in the Engine Electronics assembly as all of ours feed to the ECU.

2009 California Expectations Document Posted

Please see www.fsaeonline.com for the announcement.

Camilla: While it i the expectation of the Cost Judges that you will submit engineering documentation to support the cost methodology and values in your cost report there is no specific requirement that ever part/assembly or material have an engineering drawing. Especially for the parts that are given in the material table it is not necessary to include supporting documentation. For example a 13" Keizer wheel is known to the judges, so you don't need a picture of it to prove it - this will he handled during the on site inspection.

For something you have bought but cost as made pictures would be useful to show the judges what it looks like and if it is particularly complicated perhaps pictures of the disassembled part would be helpfull. The judges don't expect you to reverse engineer the part into CAD to make engineering drawings of it. I hope this answers your questions.

Johan Andersson: I'm not sure I understand the specefics of your issue. Did you set your region to English (United States) or not? If you don't you might get a succesfull sync message and the data will sit on the server without being processed because of the comma ( , ) issue. Remember, you don't really need to sync if you enter your data on one computer and use the GetAdminTables() command to update your Admin tables.

MattHill: Matt, sorry we haven't responded to your email. Look at the fcakey file in the c:\fca folder. Make sure there are two numbers seperated by a hyphen, such as ###-#######. If the second number is missing try typing in your authentication number and trying sync'ing again. This is a useful thing to try for any team with this same error message. The number before the hyphen is a unique team ID (not car #), so leave that in the file. The fcakey file may be hidden so make sure to turn on hidden file display from windows explorer.

SQ: I think we have an AIR for this already. I'm a bit uncertain about this - perhaps you can help me. Does this interface with the Motec controller to drive the coils?

Alex_UK: You can cost the battery however you want, an assembly or part. I think this is confusing because we're trying to leave it open ended, so there really isn't a wrong answer. Modify the file as you need to follow your costed BOM structure.

Zhefei Li: Thanks, and I like your paraphrase.

Jeff: I'm going to use Zhefei Li's summary: as long as everything is accounted for and makes sense, it's fine. I think I've replied to your bug report...but if not feel free to post here.

Claudia: Some events will have access and I still don't know about the others yet. My intention is to update the tables as we have global common costing for the Cost Event.

Johan: That feature is not available in this version.

Alex_UK: Think of Appendix C-3 as telling you the system where the part/assembly goes. It doesn't dictate BOM level. So it could be a material (of the dashboard) a part or an assembly.

For sensors: as long as everything is accounted for and makes sense, it's fine

Bill,

Regarding the Motec Ignition Expander:
The Motec ECU sends a single pulse to this device for every cylinder fire. This is then hardwired in sequence to spark the right cylinder. So there is interface, but it's only in one direction: the ECU out to the IEX.

The point behind the device is that the Motec ECU has 4 ports devoted to ignition by default. Using this device frees up 3 of those ports to be used by other auxiliary devices (fuel pump, fan relay based on engine temp, etc.)

And another question: What if I need to hand tighten something (My starter switch) that is over 6.35 mm (ours is plastic, 7/8")? This isn't really covered in the process table.

Mr. Riley,

- Should I submit an AIR for a 2-part foam mixture used to create the seat?
Description: we use this 2 part foam for a seat. 2 parts, as part a and part b, mix together they expand into a foam

- Are the potting inserts and potting adhesive included in the potting process? I sent an AIR a few weeks ago and didn't notice any distinct answer.

Thanks,
Jeff Freeman

Hi Bill,

Should the eBOM have a specific format for the file name when we email it?

Raechel,

The eBOM file name is specified in rule 3.8.1 of the main competition rules.

SQ: Thanks. From what I see on the web a fair cost for this is $150. I will add this to the tables along with the Traction Control Multiplexer also at $150. Thanks for the help.

Jeff: I'm updating the process table so the potting process includes the material cost. Also, the inserts, both styles, are being added at $2 each. The seat can be one of three things: the structural foam listed under composites, a plastic by type listed in raw materials or if you don't think either of those apply you'll need to submit an AIR (or just post details here along with a website and MSRP).

Cost Team Volunteers Needed!

If you are interested in helping with the Cost rules, mostly to help analyze Add Item Requests please email me care of Kathleen McDonald at katklauz@aol.com

FSAE-Alums, Soon to be FSAE-alums or otherwise I need your help!!

If you don't like the new rules and want to influence them for next year, or loved them and want to give back please help out.

Thanks,

Bill Riley

SQ: I just realized I missed one of your questions. For items over 6.35mm you need to use a wrench, ratchet or some other tool. The idea is in production anything over 6.35mm you would give the operator a tool due to repetition.

Sorry I'm bombarding you with questions, but it's crunch time..

I've got a simple, manufactured water temp sensor (a simple probe wired to a 4 digit 7-segment LCD display). I find all these parts on here, but this part seems to me to fall more along the lines of the Analog Gauge category. Any thoughts?

Ah ok. I just wasn't sure because Rule 3.8.1 mentions a PDF. Thanks!

Mr. Riley,

I'm a bit unsure of the formulas for costing the fasteners. Should I be able to copy/paste from the fastener table into my unit cost field and insert the values for C1 and C2?

The reason I'm asking, is I've been trying to calculate them other ways and am getting different numbers. I think it all stems from a parentheses question. The fasteners table reads:

[C1]/105154*[Size1]^2*[Size2]*SQRT([Size2])+([C2]*EXP(0.319*[Size1]))

and this to me is saying:
([C1]/105154) * [Size1]^2*[Size2]*SQRT([Size2]) + ([C2]*EXP(0.319*[Size1]))
with emphasis on having the 105154 value as the only thing under the division sign.

Could you verify that this is correct?

Thanks,
Jeff Freeman
