Homework Help: Force/Impulse Equipment

  1. Jun 12, 2007 #1
    I'm looking for something that can pull on a string at a constant force per second

    So that i can graph Force (n) over Time (s) just like that:

    Picture 2.jpg

    in this graph, the red line represents the tension of a string as i pull on it. However, i really need that slope to be constant.

    By the i'm investigating how different force per second affects the breaking force of the string

    From preliminary experiments, i observed that that:

    Picture 4.jpg

    the trough of the graph is when the string breaks.

    The larger N/s applied, the string breaks at a higher tension
    The lower N/s applied, the string breaks at a lower tension

    WHY IS THIS SO? which equations can i use?
