1) A 605 gram aluminum bar has the following dimensions length 0.75 m, width 0.010 m and height 0.030 m. The bar is clamp at its center and struck along its length, the measured frequency is found to be 3333 Hz. Determine the measured speed of sound within the metal bar.
2) The Young%u2019s modulus for aluminum is 6.7x10^10. Determine the theoretical speed of sound for the metal bar.
