bike um couple people so a lot of times again adjustability and and pack go hand stiffness which was something that was really important to all of us yeah given that you have you showed the uh the UCI
bike um couple people so a lot of times again adjustability and and pack go hand the frame stiffness uh we've actually improved the head tube stiffness which
bike um couple people so a lot of times again adjustability and and pack go hand is the front end stiffness of the frame um
bike um couple people so a lot of times again adjustability and and pack go hand and uh the BB stiffness is the same as a P5 um and we found that those are those
beds, how the tendons relate. All of these tissues end up getting sticky and they don't slide very well and then they get stiff. And that stiffness is one of the problems that happens. And so if I'm dehydrated and then I freeze myself in a 90-degree position. You can imagine that after a while that's gonna be a recipe for pain. I don't know what's happening, but I used to be a college swimmer and now I can't put my arms over my head.
And although that will change whether the springs are in series or parallel, it won't change how long the system actually is. So you can change the stiffness without changing the length. Now look at what happens if you give the mechanism a nudge in its original series state.
which is what you see in front of you um the there was a lot of potential in some of the first ones but there we were getting structural challenges with having enough stiffness in those systems so um in the end we went with this approach um as it gives a good
So here's something that's fairly stiff, but it's also not very dense. It's got near the stiffness of a solid part, but because of how this lattice structure is created, a lot of the stresses are translated linearly through the part, and so we've got a very stiff material.
So the original form of Euler's identity has a transparent geometric meaning that's obscured when we write it in terms of pi. And the cause of proportionality is essentially a measure of the stiffness of the spring, is the spring constant k.
And then there's also in the legs and the lower part, there's making forms and character with the fabric as a loose cloth. There's nothing inside but layers of-- interfacing the stiffness , a stiff sheet, and it's really to do with the way the cloth is cut. The chair on the right, Liz, is a similar thing, but more voluptuous forms in the bottom.
major major proponent to the use cycle and funny interestingly enough our sixth priority was aerodynamics and our seventh was stiffness um so and that's where we started so then again the question is how do we
And that slope is the Young's modulus. And that sort of tells you-- that's effectively the stiffness of the material. So if we want a material that's soft and rubbery, we need something with a very soft or very low slope right here.
So my background comes in this class of materials called shape memory polymers. And these polymers are plastics that can change shape and stiffness at different temperatures. So these are plastics.
So how these plastics work-- I won't get too deep into the chemistry-- but a lot of materials, if you look at them as a function of temperature, are fairly stable in terms of their modulus or their stiffness . But if you've ever taken a racquetball and dunked it in liquid nitrogen and thrown it against a wall, or taken a banana and gotten it really cold,
What I do if a patient comes to my office, whatever their problem is, and however severe it is, people are often shocked. Cholesterol are actually what make our cell membranes have structure because they create stiffness , whereas the omega-3s and omega-6s actually
And I'll show you some of our curves in just a minute. But so what we have is a couple ways now to engineer the effective stiffness of a material. One way is by tailoring the stress strain curve, and another way is by tailoring this internal geometry.
of the telescope's detectors. Honeycomb mirrors also have a ribbed structure behind them to support the mirror's face for high stiffness . But still, for decades, we were only able to capture visible infrared and UV light.
It affects about a million Americans, 10 million people worldwide. Most people think of Parkinson's disease as a movement disorder-- problems with slowness of movement, stiffness of muscles, shaking, difficulty with gait and balance.
One of the things that we spend a lot of time on is we play with internal structure in 3D printed parts. So here you'll see six little wafers of the exact same material, but the effective stiffness of these materials ranges dramatically. So here's something that's fairly stiff, but it's also not very dense.
Working class Americans were seen in straight straw hats or green blouses, but the clerk had a certain kind of collar. It was usually bleached in immaculate white, and it was starched into imposing stiffness . The color business shirts were actually quite expensive, so even Brooks Brother's used to sell collars by themselves.
has gone to Afghanistan. We know it's been deployed with our Navy Seals. And it's very, very simple. It's like putting air into a compressed tank. And that second model of stiffness and position first, and then breathing second.
This shot is from the inside a wind tunnel. And in Formula One, it's very easy to go off into the boonies worrying about front toe stiffness or various engineering esoteric things, which
And those changes occur in vision, motor control, speech and hearing, cognition, attention, learning, memory, but sometimes do-- are reduced hand-eye coordination, fine-motor control, strength, reduced strength, slower movements, and stiffness .
through the part, and so we've got a very stiff material. We've got other ones that have the exact same density, but by having different internal geometries, we have a huge range in the effective stiffness of these parts. So by being able to selectively control internal geometries during this 3D printing, we can do a lot of things
So when you warm it up, it won't fatigue unless you stretch it pass this endurance limit. So the question was whether we were focused in medical markets, because it seems like this control of stiffness and internal geometry
This is being inserted into a warm environment through a 100-micron slit. When it heats up, these materials can change shape, can change stiffness . So in this case, we're self-coiling a matrix address transistor array around a two-millimeter cable.
This is just allowing this wood to not create too much of a vacuum. The reason for this is that the bindings, aside from sealing the end grain, they actually change the stiffness of the joints from the sides to the back,
whole flax seeds golden flax seeds although you could use Brown flax seeds and also ground flax and flax becomes won't sleep as well there's a lot of different kinds of symptoms that you could feel when you you don't digest well you could get stiffness in your
Number two, again, something else Barefoot Ken Bob said is that, "When in doubt, relax." If your stiffness or soreness, you are tense somewhere.
