A massless bar of length L = 2.42m is held in equilibrium as shown in the diagram below. The bar makes an angle of ∅ with the horizontal. The upper end of the bar is attached to a rope which exerts a force of magnitude T > 0N in the negative x- direction. A ball of mass m = 5.65kg is suspended from the bar a distance 2L/3 along the bar. The bottom of the bar is held in place on a rough horizontal surface by friction. The coefficient of static friction between the bar and the surface is μ = 0.409.
For what angles can the bar be in equilibrium? ___degrees ≤ ∅ ≤ ___degrees
