One end of a uniform 4.0 m long rod of weight is supported by a cable. The other end rests against a wall, where it is held by friction. The coefficient of static friction between the wall and the rod is .50. Determine the minimum distance from the point A at which an additional weight can be hung without causing the rod to slip at point A. The additional weight being added is the same as the weight of the rod. The wire forms a 37 degree angle with the rod.
