The lowest string of a certain guitar is 64 cm long and has a mass density of 6.3 g/m. The string is fixed at its ends by the bridge and the nut of the guitar. (a) What tension in the string is required to tune it so that its fundamental frequency matches the E2 musical note at 82.41 Hz? Give an answer in both N and lbs. (b) The effective string length can be shortened by pressing your finger down...

Assume that the length of the section that vibrates in the strings of a guitar is 1 m, this is the distance from the bridge to the nut. The second string from the top, out of six, is conventionally tuned to A two octaves below concert A. This is written as A2, and the note has a frequency of 110 Hz. The A-Major scale starting at A2, with the respective frequencies in the Pythagorean Tuning is: A2: 110.00 Hz. ...

Questions: 1. Explain how you can raise the pitch of a note on a guitar by altering the string’s (a) length, (b) tension, or (c) thickness or mass. Be very specific about what you would do to raise the pitch. 2. If the fundamental frequency of a guitar string is 250 Hz, what is the frequency of the second harmonic? Of the third harmonic? Explain. 3. Consider a vibrating guitar string. The loudest harmonic is the fundamental, but many higher...

Write clearly and show your work for all problems. Not all problems will be graded in detail 1) You've been hired by Fender Musical Instruments Corporations to put your physics knowledge to work Unfortunately their previous physics employee lost all their records, so you need to do everything from scratch. Background you will need: When you play a guitar string, the musical note you hear is primarily caused by the string...

(4%) Problem 13: Using special techniques called string harmonics (or "flageolet tones"), stringed instruments can produce the first few overtones of the harmonic series. While a violinist is playing some of these harmonics for us, we take a picture of the vibrating string (see figures). Using an oscilliscope, we find the violinist plays a note with frequency f=815 Hz in figure (a). Otheexpertta.com A 14% Part (a) How many nodes does the standing wave in figure (a) have? 14% Part...

Using the string frequency equations when no tension in known, solve the following problem. You have a wire material that has a (volume) density of 7500 kg/m^3 and a yield stress of 0.43 MPa (1 MPa = 1 * 10^6 N/m^2). Find a combination of tension and a linear mass density of the wire that will cause the 1 m long wire to have a fundamental frequency of: 2 Hz 3 Hz 4 Hz without failing. In other words, at...

Question 4 1 pts You play a low G note on a guitar and the string vibrates about 100 times every second. If your friend sings a G note that is 2 octaves higher than this, how many times per second will her vocal cords vibrate?

Problem 2 [8 pts] Oscillator As a quality control technician at a violin string factory, you cut a sample of E-string off a large roll. The sample that you cut has a mass of ms = 1.021 grams and a full length of 2.5 meters. To test the string, you stretch some of it across a length L = 0.35 m, applying tension by means of a hanging mass m (as pictured). A variable frequency oscillator is used to excite...
