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.
