Answer to Question #126884 in Physics for maxine maranan

Question

A rod 2m long, 2cm in diameter and 5 kg in mass is fixed at one end and is stricken by a force F to produce a 3rd overtone and elongates at 1cm. A string of length L and mass 750 grams is pulled by a tension T = 30N to produce a 3rd harmonic frequency. Determine the force F and length L that produces the same value of frequencies in the two materials, if the sound wave produced by the rod was heard 0.25 seconds later by a listener 3 meters away. What are the frequencies produced and speeds of propagation of waves?
