In rotation, force becomes torque, mass becomes moment ofinertia, and acceleration becomes angular acceleration.
在旋转时，力变成力矩，质量变成转动惯量，加速度变成角加速度。

If it waits another fraction of a second, the forceof gravity will overtake inertia, causing the column to break, the liquid to fall back into the bowl, and the cat's tongue to come up empty.
如果它再等上几分之一秒，重力的作用将压倒惯性而破坏液柱，液体会落回碗里，而小猫的舌头则扑了个空。

In the analysis of the stress and deformation under dynamic loading, the inertiaforce and damping moment should be considered in addition to the transverse shear effect.
