Stiffness

Stiffness variance

Advance on axial 664.

Just a little stiffness. That's all.

That's not guessing. The child has a fever, headache, stiffness.

And we're going to go down into the Axial Seamount using animation.

The examiner grasps the thumb and places an axial force with grinding.

On the left hand side there is a large volcano called Axial Seamount.

And that axial tilt of the Earth is one of the main reasons for the seasons.

To perform the Crank Test, fully abduct the shoulder and provide an axial load on the humerus.

Flex the knee to ninety degrees, apply an axial force along the tibia, and rotate the tibia.

With the head extended and rotated toward the painful shoulder, apply an axial load to the cervical spine.

With the head extended and rotated towards the painful shoulder, apply an axial load to the cervical spine.

Provide an axial load on the humerus compressing the glenohumeral joint, then move the humeral head anteriorly and posteriorly.

Testing for osteoarthritis of the thumb at the trapezium metacarpal joint is done by using the axial grind test.

like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

With the patient supine and knee fully flexed, palpate the medial joint line and apply an axial force along the tibia while externally rotating and extending the knee.

With the patient supine a femoral log roll, internally and externally rotating the femur, and a heel strike, an axial force on the femur, can be performed to assess for possible femur fractures.

It's an observation with obvious medical applications in humans as well, but it's also relevant in a broad sense, I think, to the design of prosthetics, soft robots, basically anything where changes of shape and stiffness are important.

So if you're ever thinking about the issue of compliance, when we're talking about stiffness, think about these curves and the fact that where the slope is tells you how compliant something is, and that arteries are going to be more compliant than a stiff pipe, certainly, but less compliant than the veins.

This painting is often compared to an early renaissance painting by Raphael's teacher Perugino The Giving of the Keys to Saint Peter and you can begin to see here in this early work by Raphael indications of what we understand now as the high renaissance style as opposed to the kind of stiffness of the 15th century of the early renaissance.
