Example 2: A traffic light weight (122 N) hangs from a cable tied to two other cables fastened to a support as in Figure-6. The upper cables are not as strong as the vertical cable and will break if the tension in them exceeds (100 N). Will the traffic light remains hanging in this situation, or will one of the cables break? 370 530 T3 37° 530 T2 T3 T3

A7.0-Mg truck is resting on the deck of a barge which displaces 329 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge vrel = 7.1 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. P'rel = 7.1 km/h 7.0 Mg 329 Mg- Answer: v = i km/h
