Physics of a bow?

  1. Sep 14, 2007 #1
    Does anyone know where I can find information related to the physics of straightening a bow from its curved state to a more "straight" condition?

    I'm not sure what you mean - do you mean the actual fuctioning of a bow or redesigning it to a different shape?

    I mean, in terms of applying a force to one end to straighten the bow out.

    Thanks for the article also...I just wish I had a credit card :(

    Bows are normally made with a curvature in mind.

    Straightening depends on the material, e.g. wood, plastic, horn, . . .
    http://en.wikipedia.org/wiki/Composite_bow

    One would have to heat the bow to soften the material or make it more maleable, and then deform it to a straighter profile, and then cool it. The success will vary according to the material, or it may not work at all.

    Iknow bows are made in that respect, but this is related to a project I'm doing with a bow appearing to be a suitable model of reference.

    What does one mean by "a bow appearing to be a suitable model of reference."?


    Simply reducing the tension on the bow string will make bows straighter.

    Oh, I was thinking of a model where pulling down on one end of the structure leads to a straightening out effect.

    J E Gordon's excellent book "The New Science of Strong Materials: Or Why You Don't Fall Through the Floor" or the follow up " Structures: Or Why Things Don't Fall Down" has a section on the physics and engineering of bows.

    They are also the best popular books on materials and structure engineering I know of and really deserve to be more widely knonw.
