| Electricity is a repulsive force. Electrons repulse one another. They must push. |

Electricity is an attractive force. After all, electricity is what keeps me from pulling fragments off my desk. (Rubs balloon on cat's fur and sticks it to the wall.) Electricity is an attractive force. (Etc.) So, what does that tell us about electrons? Maybe if you did something more than word salad and tired inapt analogies, you might learn something. But I'm doubting it. socks |

Link to link the links are in compression, while all the rest of the parts of the links are in tension. The link arrangement is prevalent in European railcars. |

The cables are in tension but combined with the pipes they run through they create a 20 foot tall (perhaps) rigid structure. Conventional triangulation keeps it from falling over. |
