Determine the maximum allowable weight of a load supported by chains.

  1. Sep 30, 2007 #1
    Please help me figure out how to solve the attached problem.

    I understand the equilibrium equations for 2 chains (http://www.glenbrook.k12.il.us/gbssci/phys/class/vectors/u3l3c.html) but not for the third chain attached to the load.

    Thanks-

    Lith

    Draw a free body diagram and you will see how the 3rd chain comes in. Point A is a good place to isolate for a FBD.
