A quick and simple problem

  1. Aug 27, 2003 #1
    Hi

    I have a simple and quick problem, located at: http://www20.brinkster.com/kaisolutions/prism.htm

    I have calculated the second part which has been confirmed as correct: F = (mg) / 2(ìCosá - Siná)

    But im not sure how to do the first part which i suppose is easier! Thanks in advance,

    Sorry the symbols didnt display correctly:

    ì = Coefficient of static friction
    á = Angle at the top of the prism

    Thanks,

    Maybe this is not as easy as I thought? I thought it would be along the lines:

    á = Tan(ì)

    Any help is appreciated :)

    Umm. Which way is gravity? The crane will never be able to support a weight by applying downward forces...
