A massless bar of length L = 1.81m is held in equilibrium as shown in the diagram below. T 2L 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 7' > ON in the negative x-direction. A ball of mass m = 5.74kg is suspended from the bar a distance 24 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 H = 0.31. (The input below will accept answers with no more than 1% variation from the correct value.) For what angles can the bar be in equilibrium? degrees s es degrees
