Came to post about FutureTruck. I wasn't in my school's (Wisconsin) group, but I can tell you this - 1st thing to do is to lighten that pig up.

I recall in the early 2000s that they had a local manufacturer donate a hydroformed aluminum frame. I don't even want to think about how much that sucker cost. Since they had the truck apart, they started chucking/replacing other parts.

That savings in weight allows you to accommodate more batteries, improve towing performance, or just improve fuel economy.

If I remember correctly, my school's team ran a series hybrid similar to the parent. They might have had regenerative braking, not sure.


If you are planning to sell this as a kit, replacing the frame isn't really an option. I'd focus on the motor (duh), battery size and location, regenerative braking, and lightening components that can be easily accessed.

What you might want to look at is working from a crossover SUV platform. Unfortunately, those car/trucks tend to be pretty damn heavy too...

are you working while at school?

I was a TA while I was in grad school. Got tuition PLUS pay PLUS healthcare. I would HIGHLY recommend looking into that. Definitely helps relieving future debt.

1) Grade papers 2) get drunk 3) grade more papers

We worked maybe 32hrs/week after considering grading papers. Remaining time was for my studies. I was a lazy student though - I had to keep a B average to keep my TA job though, so I had a bit of motivation :-)

The new frame is larger than the old one - maybe he designed some cushion into it?

Depending on his discipline, the prof would give him a A for unique design, ergonomics, or mass-producability (prototype was 3D lathed, but design could be cast?). Drop test durability would fall under a mechanical engineer, imo.

grandparent is referring to Toe-in. You need some to keep the car stable, but excessive toe-in will create tire wear.

Some cars that are going to be constantly side-loaded (Nascar, for example) will run negative camber to improve tire contact in turns.

Under normal driving conditions, loading one sidewall more than another could lead to premature failure of the tires.

Since I don't know how to direct down the page... [from the wiki article]

However, a special prosecutor assigned to the case brought charges against 650 people, which did not result in convictions.[1] Three Chicago election workers were convicted of voter fraud in 1962 and served short terms in jail.[1] Mazo, the Herald-Tribune reporter, later said that he found names of the dead who had voted in Chicago, along with 56 people from one house.[1] He found cases of Republican voter fraud in southern Illinois, but said the totals didn't match the Chicago fraud he found.[1] After Mazo had published four parts of an intended 12-part voter fraud series documenting his findings which was re-published nationally, he says Nixon requested his publisher stop the rest of the series so as to prevent a constitutional crisis.[1] Nevertheless, the Chicago Tribune wrote that "the election of November 8 was characterized by such gross and palpable fraud as to justify the conclusion that [Nixon] was deprived of victory."[1] Had Nixon won both states, he would have ended up with exactly 270 electoral votes and the presidency, with or without a victory in the popular vote.

I should correct myself. The OS itself wasn't crap. The fact that NOBODY developed for it made the experience with the OS crap.

Before Vista came out, we had one machine in our office running XP64. We use primarily Solidworks and they came out with a 64-bit version of their software. Completely buggy and some files weren't compatible with the 32-bit versions of them. Complete fiasco when you're staring down a deadline.
Eventually, they fixed it and now things are seamless. I have more machines running 64bit, but am limited because our stupid VPN can't handle 64 yet...

My experience with installers/programs that don't run in Win7-64:

"Did this program install/run correctly?
Windows detected an unexpected crashing of your program. Would you like to run the program again in compatibility mode?"

Lots of problems solved that way.
If that doesn't work, there's always my dual-boot of WindowsXP I have on my machine, though I haven't had to touch it for months.

The Proton Just Got Smaller 289

Posted by samzenpus
from the size-does-matter dept.
inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

Comment: Re:How Fast? (Score 1) 459

Generally, if you can generate lift at low speeds, you generate more lift when you're going fast. At some point, that extra lift just becomes a drag to your plane.

Consider a current jetliner. They employ very complex flap systems to alter the shape of the wing to increase its lift for takeoff and landing. A larger, squarer wingspan will generate more lift, but that lift becomes an issue at higher speeds. A smaller wing cross-section infers a weaker wing, which also limits the lift a wing can generate.

A 10% hit in airspeed is worth a 50-70% gain in fuel efficiency. Don't expect to see this reflected in your ticket price ;-)

Those who can, do; those who can't, simulate.
