Chapter 12, Problem 77P

Figure 12-81 shows a 300 kg cylinder that is horizontal. Three steel wires support the cylinder from a ceiling. Wires 1 and 3 art attached at the ends of the cylinder, and wire 2 is attached at the center. The wires each have a cross-sectional area of 2.00 × 10⁻⁶ m².Initially (before the cylinder was put in place) wires 1 and 3 were 2, 0000 m long and wire 2 was 6.00 mm longer than that. Now (with the cylinder in place) all three wires have been stretched. What is the tension in (a) wire 1 and (b) wire 2?
