A pole is attached to a wall with a hinge as shown. A sign is suspended at the other end of a pole, where D2 2.50m. A cable attached to the wall forms an angle a = 24.0° with the wall, and is attached to the pole a distance D %3D = 1.60m from the hinge. If the origin is at the hinge, the weights of the pole and sign make a total torque on the pole of 545NM. What is the tension in the cable?
