Reference no: EM13679471

1. A steel bar is clamped at both ends. The bar is 20 m long. Draw the fundamental, and the second and third harmonics of the standing wave. Determine what are the three wavelengths?

2. If the velocity of waves in the bar is 10,000 meter per second, find what are the frequencies of the three waves?

3. The same steel bar is clamped in the middle, with both ends free. Sketch the fundamental. Find what is its wavelength? Find what is the frequency of the vibration? (Use velocity of 10,000 meter per second).
