A 300N uniform rectangular sign 4m w is suspended from a horizontal, 5m-long rod, so that the sign's right edge is lined up with the rods right end. The w of the rod is 80N. The left end of the rod is supported by a hin ge and the right end is supported by a t cable making a 20 angle with the horizontal, as shown in the picture. Find the te nsion in the cable, and the horizontal and vertical components of force exerted on the left end of the rod by the h ing
