Shortening a pull distance

  1. Oct 29, 2007 #1
    I'm working on a project for school and I have to come up with a system where a pulled object moves twice as far as the object doing the pulling. I think I've seen a pulley system that can do this, but I can't remember where. If anyone has any suggestions, I would greatly appreciate it.

    Have you searched on "block and tackle"?

    Thanks for your replys, I think I'm going to go with a scissor system. I think that may work best in my project.
