Physics: Simple Harmonic Oscillator

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

Traveling waves are set up in a pair of long strings by a simple harmonic oscillator. The strings have identical mass densities of 5.1 grams/meter. Both strings terminate at a short bungee cord attached to a wall. The harmonic oscillator is attached to the other ends of the strings in such a way that one string is 5.4 meters longer than the other. If the oscillator has frequency 97 Hz:

Give at least two string tensions which will produce the minimum motion of the bungee cord.
