A string is attached between the end of a narrow uniform beam and the wall. Friction on the beam keeps the left side from falling. The magnitude of the weight of the beam is w (position is given in meters). Restart.

1. What is the ratio of the tension in the string to the weight, T/w?
2. What is the magnitude and direction of the force of the wall on the beam?
3. What is the minimum coefficient of static friction required for the left end of the beam not to slip?
