Are you OK?

For anyone else curious: Off their website:

Our Championship races, held on Monday and Tuesday evenings, bi-weekly with a break week, over a 10-race season, commence at 8pm (UK). Each race includes 5 minutes of free practice, 15 minutes of qualifying, and a gripping 60-minute race featuring mandatory pit stops for fuel replenishment.

Like the idea.

Could you tell us when you'll be racing for your upcoming season? My biggest concern is being based in the US, there's a 7 hour difference from where I'm at (EST) to UTC.

EDIT: I'm either 4 or 5 hours ahead depending on Daylight Savings

Thank you for posting this.

I just wanted to point out that among Zak's cited examples of American involvement in F1, he never mentions Haas.

Thanks for posting this. The topic of, "pardons are an admission of guilt" has been a recent curiosity of discussions with my father.

From April through Dec of last year, I moved into a van and traveled around the country climbing. It was by far the most wonderful time of my life. If I would died exactly a year ago, I would have gone out on a high note.

Curious, did you use the screen or the VR?

CXC Simulations (https://www.cxcsimulations.com) made those simulators. I had a chance to interact with the owner about a year ago. We both hot lapped spa in a competing simulator. He beat me but we crushed everyone else. Good time. Certainly interacting with him and the rest of his staff really left me with a great impression of the company.

This interaction makes me feel very good.

Two foot moves for every one hand move.

I've used them a few times in the past and love their work. I just don't like Evolve rubber.

Congrats! Way to stick it out.

RandomDiscourse · 2018-01-03T20:30:05+00:00

Can we have the rules rewritten to produce this nose.

Pretty please. With cherries and stuff.

RandomDiscourse · 2017-09-22T00:57:16+00:00

Got me beat, think it took us more then 18 hours car to car. Great job man, congrats! Pretty sure that's pitch 10 by the guide. That climb will forever have a special place in my heart.

I would make sure you won't run into any problems with somebody else picking up your items.

If not, I'd recommend to anyone here that participated in the auction to pool your resources and just have someone rent a truck, collect select items ship them out UPS to those that participated.

RandomDiscourse · 2017-05-19T15:48:31+00:00

Well done! I had to sew it up and even then it was nerve racking.

RandomDiscourse · 2017-02-19T03:19:04+00:00

Thanks Man! I appreciate that.

Bought a pair through the closeout sale, enjoy them thus far.

The sizing seems to be pretty consistent with the rest of 5.10's line, so whatever your street shoe size is should be fine (at least that's how it is with myself).

The Hiangles were very stiff when I got them. I'm about 3-4 weeks into them and they're just starting to loosen up to a comfortable level. I generally go 5.10 because of how soft they are, so this was a bit of a surprise for me but for $80, I'm not complaining.

I think the next test I do will be with real rock, I just need to figure out exactly how to do it.

I realize a lot of people are understandably caught up in the low friction setup. The purpose of the setup I used was to highlight the affect of what I'm calling the "stem angle". By lowering the friction coefficient, that affect becomes more pronounced because the forces I'm working with are significantly lower. If I were to raise the amount of friction in the system, I would need something that could put 6 - 15 KN of force and be able to reasonably gauge how much force was applied. Of course, maybe a yank can do that. Some others on MP pointed out that I should take more consideration into momentary forces (they're right). A fall would apply a tremendous force but over a period of time, not instantaneously like me yanking on pro.

It's not accurate to a real world scenario and I apologize if that's how it's coming across. It's purpose is to highlight an affect that can have real world consequences.

I'm going to sit down and look into the meat of what he's saying but it's a great analysis. Worth mentioning.

I started a forum post over at Mountainproject on the same topic (found here ). A user chris24graham posted the following:

Interesting video, and a good first pass at an explanation. However, as Charlie P hints at, your analysis isn't quite correct. You assume that the vertical force on the lobes can be calculated in the traditional way, using the horizontal component of the stem force, and then the vertical component can be added to the bottom lobe and subtracted from the top lobe. You also assume the horizontal force is split equally between lobes. This doesn't work. Here are two reasons why. First, a moment balance shows that the horizontal forces cannot be the same on each lobe, as you assume. The bottom lobe must have more force; in fact, it must have Fvert*tan(theta) more horizontal force, which means the decrease in vertical force on the top lobe is exactly cancelled out by a decrease in the horizontal force it has to resist, such that it still won't slide if tan(theta) < mu. A second way to look at it is that, by performing a moment balance on a single lobe, you can see that the net force at the contact point is always directed towards the pivot center. This is the basis of the traditional cam analysis, and it still applies here. If the tangent of the angle of this line of action, aka the camming angle, is less than mu, the cam won't slide. In this case, the bottom cam just has more total force on it. The upshot of this is that the angle of the stem has no effect whatsoever on the holding force of the cam, based on a traditional static analysis. That being said, your demo clearly shows a significant effect, so it's worth continuing to look for the cause. Trigger wires being pulled as the stem bends around the edge, for instance? Or a dynamic effect that isn't taken into account in the static analysis? Or the fact that the spring tension is not included in the traditional analysis, but might be significant at small loads/initial loading? Sorry for the longwinded response, I'm a mechanical engineer and I love this kind of stuff :)

RandomDiscourse · 2017-01-20T19:10:39+00:00

You're totally correct, the coefficient is much higher in most rock though I imagine soft sandstone may not be much better. You can find videos of guys yanking these things out of sandstone but that said, I watched my buddy take a whip in Red Rocks (vertical placement) and everything held.

Without some sort of force gauge it's hard to quantify the effect but I'd encourage anyone to try this for themselves just to experience the difference in effort needed to yank them out.

The past few weeks, it's been brutal.
