A damp washcloth is hung over the edge of a table to dry. Thus, part (mass = mon) of the washcloth rests on the table and part (mass = moff) does not. The coefficient of static friction between the table and the washcloth is 0.350. Determine the maximum fraction [moff/(mon + moff)] that can hang over the edge without causing the whole washcloth to slide off the table

  1. friction force=masson*.350g

    force pulling=mass0ff*g

    forcepulling=frictionforce
    moff*g=.350Mon*g

    so massoff=.350mon

    so the fraction must be massoff/(mon+moff)
    = .350mo/(mo*1.35)=.35/1.35

    check that.

  2. thank you!
