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

这些可编辑的属性力、质量、刚度，我们甚至还可以往场景中添加新的力。

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

CHIARA：我们真的很想制造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。

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

她刚度完蜜月回 但这场蜜月却有如笔生意。

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

早安, 姜妹, 刚度完假?

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。

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

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.

但是现在让我们弹簧的刚度。

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。

Qj is the shearing force of the joint, ks is the shearing stiffness of the joint.

Qj 是接头的剪切力，ks 是接头的剪切刚度。

And if we increase the stiffness then we are going to make it a shorter period.

如果我们增加刚度，那么它的周期就会变短。

Because the Euler-Bernoulli beam regards the shearing stiffness as an infinite value.

因为 Euler-Bernoulli 梁将剪切刚度视为无限值。

Well we can change the stiffness of the spring.

我们可以改变弹簧的刚度。

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。

Shearing and rotation stiffness of joints is addressed in isolation, leading to a different deformation features from LECM.

关节的剪切和旋转刚度被单独解决，导致与 LECM 不同的变形特征。

Yu's method overestimates the relative stiffness of tunnel soil, which results in a large error in tunnel settlement.

Yu 的方法高估了隧道土体的相对刚度，导致隧道沉降误差较大。

13 EI represents the bending stiffness, which is usually multiplied by a reduction factor of 0.7 for considering the influence of longitudinal joints.

13 EI 表示弯曲刚度，考虑到纵向接头的影响，通常乘以折减系数 0.7。

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