One end of a uniform 4.0-m long rod of weight
w is supported by a cable. The other end rests against the wall, where it is held by friction. The co-efficient of static friction between the walla nd the rod is .50. Determine the minimum distance,x,from point A at which an additional weight w(same as the weight of the rod) can be hung without causing the rod to slip at point A.

i cant find a picture but i hope that someone can truly help me on this problem..i have been working on this for a few days now and its really pissing me off T___T please help
