| This example shows that a force component may have a mass. | |
| The 3-dimensional spring as used in this example, has an optional | |
| point mass between the two points where the spring is attached. | |
| In the animation, this point mass is represented by a small, | |
| light blue, sphere. | |

for some reason the original Wolfram community post is gone, so I upload it hear again.
