Serway & Jewett — Wave Motion: Problem 19

A horizontal string can transmit a maximum power \( P_0 \) (without breaking) if a wave with amplitude \( A \) and angular frequency \( \omega \) is traveling along it. To increase this maximum power, a student folds the string and uses this "double string" as a medium. Assuming the tension in the two strands together is the same as the original tension in the single string and the angular frequency of the wave remains the same, determine the maximum power that can be transmitted along the "double string."
