Hi Geoff,

OK here near Buffalo/Niagara, at least so far...

Your memory is good, I'd forgotten Toyota Corona. Drove a well-used example in the 1980s, lots of body roll & pitch, iirc (but...

Geoff,

Great to hear from you.

When questions come in, I often send links to FSAE.com. If the local search function lets me down, I use Google site search. For example, Google Image search...

I'm interested in hearing any other comments about this event, from students and/or volunteers.

Here are some initial comments after WebEx judging with 10 teams over the last two days:

+ In...

As one of the last(?) posters here, I thought I'd open a topic to discuss the 2020 design event. For anyone that doesn't know, due to the virus, this year's event will be online. SAE and many...

Of possible interest to FSAE and Mini-Baja participants, I've been asked to announce several research positions being offered:
...

That would be a job for the "wheel test consortium"!

As interesting as this test might be, we have enough trouble sourcing zero offset wheels for TTC testing as it is. With different offset...

Sorry to say, that SPMM was auctioned off last year and is being rebuilt for the new owners in Asia. Perhaps we'll see some K&C data from the updated rig...on a car from that side of the world?

The FSAE Tire Test Consortium now has 600 members worldwide. While this FSAE.com site is short on contributors these days, it is still full of useful information--thanks to the site operators for...

You may need to go back to the rig operator to really understand what was tested? Based on experience, I think I can guess, but that isn't good enough. K&C measurements depend on precise...

Thanks Bill, those are great slides. In my FSAE lecture I try to cover some of the same ground. After an overview of tire force and moment properties, applying the tire data to a vehicle model...

For anyone who doesn't go back a few years in FSAE/FS, here's one article where Pat defines "Motorsport Virus":

Welcome back Z, nice to see you posting here again. FSAE.com is pretty quiet, but not completely dead (yet?)

Here's the acceleration video I found, https://www.youtube.com/watch?v=kQo1CndWHg8 ...

I'm a little late with this sad news, from June 2019. If you don't know about Robin Herd, you are missing some great race car engineering stories.
...

I always read/post here from a laptop. How well does this site display on different kinds of phones?

Welcome back FSAE.com ! Not sure what was wrong, but it's been several days (or a week) that I couldn't access the site.

If you want to see what others have done, there is a lot of info on this forum. The Search isn't very good so use Google site search, this string gave me ~60 hits, many of them are worth reading:

> As for rack over constraining ...

The worst cases I've seen are often with a short rack (junior dragster?) that is extended, and then additional bushings are added to support the longer rack...

Good discussion!

In design judging, I've often used a quick test that someone told me was the "Carroll Smith steering friction test". With the front tires lifted off the ground, move the steering...

Seems to me you are asking the wrong questions(?)

Whenever I've design judged, one of the most common problems is a steering system with far, far too much friction to allow precise steering by the...

Elsewhere in this forum, Bill explains his methods in more detail. Unfortunately the FSAE.com Search seems to be broken (at least for me). The first few hits from this Google search point to some...

Ref. RCVD p.310-311 - It looks like you are having problems with the third case in Table 8.4 -- which we call CN-CY, finite radius, road load. Increasing speed on a constant radius increases CY...

A bit of history -- Brian's post above was from just over ten years ago, back on page 16 of this long thread -- 01-21-2009 01:45 PM. This started a long run of Washington State U successfully...

Hi Justin,

Do any of your flights get to Buffalo? Plan to stop and say Hi.

Thanks for the links and I see Bill has edited his plots--axis labels are fine now.

Thanks Bill, a nice way to look at the range of solutions and spot in the lowest weight for each engine displacement.

When I look at the plot you posted here there are no X and Y axis labels...
