rotational motion造句怎么写

In an engine the linear motion of the pistons is converted into rotational motion by the crank shaft.

Elevation, tilt, overhead reach, and rotational motion features allow easy access and appropriate positioning of objects.

The restoration of rotational motion blurred images with the boundaries of non zero gray values is a study hotshot in the field of image processing.

Angular momentum can accompany nonrotational motion.

These equations most briefly demonstrate the relationship between rotational motion quantity of body and principal moment of force system.

Traditionally, artificial knee-joints use hydraulic damping, which presents more angular resistance to fast rotational motion than to slow motion.

But with such a shell, we find that there emerges a deeper type of symmetry, not evident at first: for the shell has a symmetry under rotational motion, provided that this is accompanied by uniform expansion or contraction.
