Homework Help: Static friction and fraction of mass of rope that can hang.

  1. Mar 2, 2013 #1
    1. The problem statement, all variables and given/known data

    The coefficient of static friction between a rope and the table on which it rests is μ.
    Find the fraction of the rope that can hang over the edge of the table before it begins to slip.
    Express your answer in terms of μ.

    2. Relevant equations

    3. The attempt at a solution

    i have tried to break all the equations i know into their parts like x and y components using just variables since no numbers are given but i just can't seem to isolate for something multiplied to μ. For some reason i think it is just μ but i do not truly understand why this would be if anyone could help it would be really appreciated as it is the last question in an online assignment and i have been working at it for quite some time. Thanks in advance.
