(17%) Problem 4: Three ropes are connected to a metal ring of negligible mass, as shown in the diagram. A traffic light with a weight of F. =207 N hangs from rope 1, which is vertical. Rope 2 and rope 3 are connected to a horizontal roof and make angles of p =61 * and 0 =31 * with the horizontal, as shown. Let Fri , Fr2, and Fy3 be the tensions in ropes 1, 2, and 3, respectively.
