27. A sign of mass 100.0 kg is hanging by a cable from the end of a support rod 0.400 m long. The support rod is perpendicular to the wall. Another cable, making an angle of 60 with the wall, is attached to the end of the support rod. The support rod has a mass of 36.0 kg, and has uniform density so its center of mass is in the middle of the rod. a. Calculate the tension in the...
