These editable attributes include gravity, mass, stiffness, or we can even add new physical forces to the scene.

这些可编辑的属性包括重、质量、刚度，我们甚至还可以往场景中添加新的。

We really wanted to make a material that can change stiffness on command.

CHIARA：我们真的很想制造一种可以根据指令改变刚度的材料。

And we're going to talk about stiffness and stability, I hope.

我们将会讨论刚度和稳定性，希望如此。

But that same lack of material reduces the rigidity and stiffness of the structure.

但同样缺乏材料会降低结构的刚度和刚度。

For those worried about earthquakes, seismic testing is often a key part of the design development phase, and because  of the strength, stiffness, flexibility and low weight of mass timber, it can often be  a better choice than traditional alternatives.

对于那些担心地震的人来说， 抗震测试通常是设计开发阶段的关键分，而且由于大块木材的强度、刚度、柔韧性和低重量， 它通常是比传统替代品更好的选择。

But it's not actually necessary to melt steel to make the buildings come down… When you reheat steel to about 500 degrees Fahrenheit, it starts to lose some of its strength and stiffness.

但实际上并需要熔化钢材来使建筑物倒塌… … 当您将钢材重新加热到大约 500 华氏度时，它开始失去一些强度和刚度。

And by having this, not only will you be able to feel how big the object is, the roundness and the lines, but also the stiffness and the texture.

有了这，仅能感觉到物体的大小、圆度和线条， 还能感觉到刚度和质感。

Finally, some materials are more resistant to changes in volume -- and that stiffness is measured by the bulk modulus, represented by a capital-B.

最后，一些材料更能抵抗体积的变化——这种刚度是通过体积模量来衡量的，用大写字母 B 表示。

This is a natural polymer that gives wood its stiffness, but it is treated as a waste product when wood is processed into paper.

这是一种天聚合物， 赋予木材刚度，但在将木材加工成纸张时， 它被视为废品。

Just back from her honeymoon, she was pre-occupied with marriage business.

她刚度完蜜月回来 但这场蜜月却有如一笔生意。

(Yorkshire accent) Morning, Ginger. Back from holiday?

早安, 姜妹, 刚度完假?

And so by increasing the stiffness of the spring we are decreasing the period of the spring.

通过增加弹簧的刚度，我们减少了弹簧的周期。

The Coefficient of the Subgrade Modulus The stiffness coefficient of the shear layer Gc is an important parameter in Pasternak's two-parameter model.

路基模量系数 剪切层的刚度系数 Gc 是 Pasternak 双参数模型中的一重要参数。

Well we can change the stiffness of the spring.

我们可以改变弹簧的刚度。

Dt is the tunnel diameter, and (EI)eq is the equivalent bending stiffness of the tunnel.

Dt 是隧道直径，（EI）eq 是隧道的等效弯曲刚度。

Each circumferential joint is modeled as a shearing spring and a rotation spring, taking into account the stiffness reduction at the circumferential joint.

每圆周节点都被建模为剪切弹簧和旋转弹簧，同时考虑了圆周节点处的刚度降低。

And let's look at how the mass and that stiffness of the spring affect the period.

来看看质量和弹簧的刚度是如何影响周期的。

But now let's play around with the stiffness of the spring.

但是现在让我们来玩一玩弹簧的刚度。

The prediction of TM-V solution is slightly larger than that of the proposed solution, because the Timoshenko beam takes no account of the stiffness reduction at circumferential joints.

TM-V 解的预测略大于所提出的解的预测，因为 Timoshenko 梁没有考虑圆周关节处的刚度降低。

Again in a spring it is going to be the mass and the stiffness of the spring.

在弹簧中，这将是质量和弹簧的刚度。
