Instructions Complete the following exercises in class on Wednesday, June 1. Feel free to work together in groups or to consult with your instructor. These exercises are for your bene±t and need not be turned in. Make sure you understand all of the material! 1. A mass of 50 grams is hung from a string-pulley system as illustrated. Suppose the string has a mass per unit length of μ = 0.01 kg/m. If the length of string between the ±xed end and the pulley is 1.5 m, what is the fundamental frequency? m Pulley 1.5 m 2. Draw the ±rst 4 harmonics for a string ±xed at both ends. Indicate the nodes and antinodes. What are the frequencies of the harmonics based on the wave speed 10 m/s and the string length of 2 m? 3. Draw the ±rst 4 harmonics for an open-closed tube. Indicate the nodes and antinodes. What are the frequencies of the harmonics based with sound speed 340 m/s and tube length 3 m? Summer 2011
