A uniform metric is placed perpendicular to a vertical wall, and at one end is attached a massless rope, which is attached to the wall at the other end. There is an angle θ between the rope and the measure. The coefficient of rest friction between the measure and the wall is 0.60. a) At what values of θ does the measure remain in balance? b) Let θ = 15°. An object with a mass of a meter is hanging by a massless rope at a distance x from a wall in a meter. What values can x take when the measure must remain balanced?
