A path is blocked by a single large boulder at the mouth of a cave. The boulder weighs 3000 kg and the worker calculates the necessary force for removal to be about 29.4 kN. Fortunately, he already has a crane to lift the rock, along with a harness to put around it, but he needs to fabricate a 3-meter long cable that will connect the crane to the harness. After rooting around in his equipment, which contains a cold-working station, he realizes that he has the brass to make a cable, the characteristics of which are shown below. Determine how much material should be used, its dimensions (diameter of the 3m long cable), and its cost.
