Problem 1 A 5.00-rn, 0.732-kg wire is used to support two uniform 235-N posts of equal length (see gure). Assume that the wire is essentially horizontal and that the speed of sound is 344 111/ s. H . a) What is the tension needed to balance the torque of the rods? b) What is the velocity of the wave on the string? 0) Find an expression for the frequencies of all harmonics
