A rod 2 meters long, 2cm in diameter and 5kg in mass is fixed at one end and is stricken by a force F that elongates the rod by 1cm and produces a 3rd overtone. A string of length L and mass 750 grams is pulled by a tension T = 30N to produce a 3rd harmonic frequency.
Interference of sound
Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
can you pls help me solve this..
- A rod 2 meters long, 2cm in diameter and 5kg in mass is fixed at one end and is stricken by a force F that elongates the rod by 1cm and produces a 3rd overtone. 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 will produce 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. What are the frequencies produced and the speedsof propagation?
•Pls answer with complete solution (3 dec places)
•Sketch an illustration/diagram with labels (this is a must; for a better understanding)
