The tensile stress in a thick copper bar is 98.6% of its elastic breaking point of 13.0 x 1010 n/m2. a 575 hz sound wave is transmitted through the material. (a) what displacement amplitude will cause the bar to break? 12.33x your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. mm (b) what is the maximum speed of the elements of copper at this moment? 44.16x your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s (c) what is the sound intensity in the bar? 4.02e10x your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. w/m2
