A group at my alma mater does this thing.

Good folks

Is it just me, or do these folks seem to have their own language?

Whatever floats their boats.

This is a very typical contest. It isn't even that difficult -the tradeoff is to have a canoe which is wide enough on the bottom to displace enough water, but narrow enough to still move fast.

also, the trick is to have someone other than the engineers that build them row them. like some sports team members.

Woo hoo civil engineers!

I know someone with concrete boots......errrr no I don't,never mind I didn't say that
 
2004-04-23 04:20:38 PM
it's water displacement, not materials.

Lilmiss - are you a civil student/graduate?

GIS for concrete:



I have absolutely no idea.

ArseParse: file name is concrete scene.. maybe its a play involving a scene with concrete?

Why all the negative vibes man? Think positive! Think "procrete".

Theoretically you could make a boat out of lead... it would just have to displace a fark ton of water.

Heh... one of my friends just ran off from here at SIUE to go to that competition. Goofy civil engineers.

Our football team's motto is "Undefeated since 1956." It lives up to it too, mainly because it doesn't exist. If it can't play, it can't lose. :) But in that case, we ended up sending CE majors out to go row the canoe.

Arse:

the filename has the word concrete in it.

do you think that shirt says "my parents really love me...."

"because nobody else ever will"
"physically"
...etc
/roll your own

TCG-
seems that every profession has its own dialect. My buddy is an engineer, and all i want to d is slap him when he starts talking his funny Pet. engineering talk. I work in the finance business, and he just stares at me with this hollow look in his eyes when i mention something remotely work-related.

I can't see the point in this. Canoe?
 
2004-04-23 04:26:59 PM
I think maybe the girl in glasses just b*tch slapped the other girl with a piece of concrete...

But at least her parents really love her.

Gee... thanks for that terrific picture in that article.

"People think Styrofoam is the only thing that floats,"

What about very small rocks?

Ha ha ha ha. You dumb bastard. It's not a schooner... it's a Sailboat.
 
2004-04-23 04:32:08 PM
This has been done for years. It's an old engineering school project.

A schooner is a sailboat, stupid-head.
 
2004-04-23 04:33:33 PM
I like how people automatically think something heavy can't float.

Uh... last time I checked, an Aircraft Carrier is gargantuan, weighs in at about 96,000 tons, and still floats pretty dang well.

Maybe its just me.

Cement Yachts have been around for years. I wonder if these uberengineers did any actual research:
 
2004-04-23 04:35:42 PM
Be afraid when engineers get bored. Back in school my ChemEng friends and I would drink a bunch of beer and mix up a batch of explosives. I have hours of tape of us blowing shiat up...port-a-potties, mailboxes, empty beer kegs, old appliances...BOOM!

Good times.
 
2004-04-23 04:38:05 PM
All they need now is the "Four Horsemen" to row it along whilst guzzling more BEvERages.
 
2004-04-23 04:41:51 PM
This reminds me of the concrete dildo in one of those Naked Gun movies.

I have no idea why..... except for the concrete.

Professional association for civil engineers employee!
 
2004-04-23 04:43:45 PM
I guess I'm the only one that noticed that this is a repeat. I only say that because the competition hasn't happened yet and the last article that was here last week was very similar to this one. Either way, it's fairly nifty
 
2004-04-23 04:46:35 PM
ParadingLunatic...
if they were very similar it's because they were both based off the press release my wife wrote.

GO UMR!

We've got concrete canoe at my school, too. A few years ago some people heavily involved in it came into my Intro to Engineering class and handed out samples of their concrete mixture with miniscule hollow glass bubbles in to make it lighter. Interesting stuff; I think I still have it around somewhere. Never did find the time to actually get involved with the group, though.
 
2004-04-23 04:49:03 PM
Why is this news?

Engineering schools been doing this for 40+ years.

I won't even bother asking why this was green lighted, we all know that's rigged.

What'cha do there?

This kind of thing isn't weird at all... It's pretty amazing stuff. Washington State University does it... The boats are really light, something about polymer eggs mixed in, anyone know for sure how it's done?

The boats are really light, I've helped carry UMR's several times. I don't believe it's as heavy as an aluminum canoe.

Oregon Tech just hosted the Northwest Association of blah blah long acronym civil engineer competition.. I judged the concrete frisbee toss.. fun fun!
 
2004-04-23 05:00:34 PM
FYI Cement boats are more durable than a lot of other kinds. Take a look at THIS.
 
2004-04-23 05:03:23 PM
When I was in high school (mid-90s), we built our boats out of cardboard.

Spoiled students these days with their fancy schmancy concrete boats.
 
2004-04-23 05:04:21 PM
Oh yeah! Take a look at THIS

"To further lighten their craft, teams make concrete using powder-like glass particles instead of rock or gravel. "

Restated in English:

"To further lighten their craft, teams don't use concrete, call whatever they use 'concrete', wink, and say 'Well, technically, it IS concrete you know.'"

Then a math major calls them stupid, and a business major headbutts them.
 
2004-04-23 05:07:39 PM
Just FYI:

Cement - powder.
Concrete - cement and water, mixed and hardened

There's no limit to what you'll do during wartime with a shortage of steel: The Concrete Ship Atlantis

They got lousy fuel economy, as I recall.
 
2004-04-23 05:18:42 PM
What's so weird about it? I thought it was fairly common for most colleges with engineering schools.
 
2004-04-23 05:24:07 PM
I build boats for a living. Concrete boats are actually quite common, particularly for large barges. Displacement and tensile strength are the only important factors. (For instance, steel is heavier than concrete, yet also floats when formed in the correct shape.)

For a really novel time, do a google search for PYCRETE. Back in the 1940's a group of scientists tried to convince the US and British war departments to build super aircraft carriers out of Pycrete (a high-strength mixture of ice and wood pulp). The proposed vessels would have been over 2000 feet in length with bulkheads 50 feet thick. Pycrete is better at impact absorption (read: bullet holes) than steel. Fun!

"Another champion team at Rolla is the mucking squad, which competes in mining skills events including drilling, sawing and dumping mining sludge"

Rolla?? Smells like an OT event....we've got concrete toboggan (spell check, table two) in the winter, too!
