@Snfoilhat: It's funny that you say that. I'm not a scientist myself, but I work parallel to an R&D department packed with them. Until recently (management change), asking questions /was/ met with essentially the same answer/attitude. I'm not saying that your experience is wrong, just that my experience has been different and coincides with the "if you care, figure it out on your own" attitude. And just a little jab: using your experience as a benchmark for the behaviour of scientists? ;P

Percentages don't mean much when tested against the same product without the tech. Aside from that, VT ratings should be taken with a grain of salt. "Other limitations pertain to testing boundary conditions. First, although simulating road surfaces using a sandpaper-coated steel anvil represents the industry standard,11,26,27,40 this setup is likely overly stiff and may have inflated results." "There are several limitations associated with the present study. First, although the impact configurations are comprehensive and based in real-world data, a finite number of configurations can be evaluated practically. There likely exist other scenarios in which helmets offer varying levels of protection. Helmets do not reduce kinematics in non-impact scenarios, which can produce rotational-related injuries (including concussion) in extreme cases. Second, the concussion risk function was derived from head impacts to American football players, who experience differing impacts from cyclists (although similar in duration and magnitude) and have skewed physical characteristics compared to the general population."

The second part of this sentence is the key. Praise is nice. But if you give children resources, they can open their minds to almost any possibility. Not to diminish his or her intellect, but given the right opportunity and environment to use the tools given, a child can make a masterpiece of mud. The fact that we don't know how to nurture that anymore could be part of the problem. But I am a simpleton.

In a perfect world most instances you're dealing with will be shearing force. So this will be either transferred into one of the strongest junctions of the frame through the threads, or simply cut through the screw. In the case of bending, the weakest link will usually be the first to expire: the inside diameter of the threads of the screws.

I still say the universe was created by a dinosaur fart. Doesn't make it true.

WTF does this even mean? Oh my god he crashed going fast! Let's all rethink our fundamental understanding of "progression!" He wasn't "progressing" anything. Just riding a bike fast and had bad luck.

@seanfeezy: 1. Are two extra letters so much more difficult? 2. You would watch it

Why don't you blame the idiot parents? And who cares anyway? Let them get smashed up. If they're stupid enough to buy into it, they deserve it.

@CaSentLeTabarnakMonHomme: I can't calm down. I'm a Canadian living in Germany. And I was right.
