What is Tuning: Definition and 136 Discussions

Hello everyone, I am new here and so I apologize in advance for the many forum faux pas I am likely to commit. I am not particularly well educated in the field of physics, but I am a piano tuner by trade, and we work with issues every day that are basically problems of physics and engineering...

Homework Statement A 40-cm-long tube has a 40-cm-long insert that can be pulled in and out. A vibrating tuning fork is held next to the tube. As the insert is slowly pulled out, the sound from the tuning fork creates standing waves in the tube when the total length L is 42.5 cm, 56.7 cm, and...

Question- when wax is applied to the surface of a tuning fork, will the number of vibrations produced per second: increase, decrease, or remain constant? Explanation would be accepted gratefully

Homework Statement A violinist is tuning her instrument to concert A (440 Hz). she plays the note while listening to an electronically generated tone of exactly that frequency and hears a beat frequency 3Hz, which increases to 4Hz when she tightens her violin string slightly. (a) what was the...

Homework Statement Using a highly sensitive parabolic sound collector, Sara records the frequency of a tuning fork as it drops into the Grand Canyon. She drops the vibrating tuning fork form rest at t=0. She records a frequency of 1783.0Hz at t=8.590s. What is the natural frequency of the...

This is my first post, so I really hope I'm not in the wrong area. I'm doing a lab is class and I'm confused as to what formula I'm supposed to use. Problem: Use the tuning forks to test the difference between perceived loudness and actual intensity. Use the formula to calculate intensity...

Two tuning forks are producing sounds of wavelength 36.0 cm and 33.8 cm simultaneously. How many beats do you hear each second? I know that the # of beats/sec heard is equal to the difference of frequency 2 and 1. Frequency = 1/T = v/lambda. Don't feel that I have enough information

Homework Statement a 512HZ tuning fork held over a bottle receives its 1st harmonic when the level of water is 17cm from the bottle opening. what is the temp of the air Homework Equations sound equation The Attempt at a Solution I have no idea where to start.

A tuning fork generates sound waves with a frequency of 246 Hz. The waves travel in opposite directions along a hallway, are reflected by end walls, and return. The hallway is 47.0 m long, and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected...

A piano wire (Y=2.0*10^10 N/m^2) has a radius of 0.80 mm and a length of 0.76 m. One end of the wire is wrapped around a tuning peg whose radius is 1.8 mm. The other end is fixed in place. Initially, there is no tension in the wire. Find the tension when the peg is turned through 2 revolutions.

Sir, 1)When one of the prongs of a tuning fork is cut, why does its frequency increase? Is it because the damping forces exerted by the prongs on each other decreases? 2)When an incident wave and its reflected wave superimpose, it is said that both standing waves and progressive...

Sir, Three tuning forks of frequencies 100Hz,101Hz and 102Hz are sounded together. How many beats will be heard in one second? If 2 forks are sounded together then the number of beats heard will be equal to the difference of their frequencies. But I don't know how to calculate the beat...

Any ideas how to use tuning forks in a science fair *high school science fair*

Is there anyway of manipulating the emission spectrum of something like a gas by pumping it with a specific input? An argon gas laser, for example, will have lots of emission lines. Is there anyway of singling out groups of those lines without changing the gas? I would imagine such a method...

Ok so I've tried lots of searching ...but... it doesn't seem to hone in on my thinking which isss... I play bass guitar and different people have different views on how much to stretch their strings to attain alevel where their style of play wil allow the strings to bend and sound great...

I would like to know about fine tuning of an airplane Fuel Gauging probe. It is basically a cylindrical capacitor made of an inner composite tube of about 0.5 inch diameter and an outer composite tube of about 1 inch diameter. The length of the tubes varies from about 3 inches to 8 inches. The...

hi does somebody knows why we hear a noise when tuning a radio? I mean when you turn the radio tuner to find a station. not for a typical station. during turning the knib. I know it's becouse of a electromagnetic wave. but I don't know that wave and its source. tnx.

is the vibrating energy of a tuning fork the same as the oscillating energy of a tuning fork?

Hi I have two probles to tackle on RLC circuits The first states that if a circuit consists of a lamp (R), variable inductance and fixed capacitor, why does the lamp glow for certain values of L. Also, you have a tuner at 100mhz, the resistance in the circuit is 15 ohms and inductance...

Hi all, I'm working through a sample midterm and I managed to get everything correct except for two, which I am a bit stuck on. Here is the first one: A 1024Hz tuning fork is used to obtain a series of resonance levels in a gas column of variable length, with one end closed and the other...

Hi, I am coming into my senior design project and I have a question. Originally, my group was going to design a new cylinder head design without using poppet valves. Being that we only have 15 weeks, we figure we don't have nearly enough time. Wanting to keep an automotive related project, I...

Remember it is a very fine tunning job, and can all the inner and outter perturbances be damped out? i put my money on a null result.

A vibrating tuning fork is held above a column of air [...] The shortest length of an air column that produces resonance is L(1) - 0.25 m. The next length that produces resonsnace is L(2) - 0.80 m. 343 m/s is what I will use for sound. How can I find the original frequency of the tuning fork...

Q: The prong of a tuning fork moves back and forth when it is set into vibration. The distance the prong moves between its extreme positions is 2.29 mm. If the frequency of the tuning fork is 440.2 Hz, what are the maximum velocity and the maximum acceleration of the prong? Assume SHM. I...

Q: A tuning fork vibrates at a frequency of 264 Hz and the tip of each prong moves 1.66 mm to either side of center. Calculate the maximum speed of the tip of a prong. So far I've found that Vmax = omega*A, but I don't know how to find A. Am I going in the wrong direction? Or is there a way...

I have a 62cc engine on the back of a scooter frame made for an unmodified 41.5 cc engine. The engine is putting out a ton of power for what it is, 8hp maybe from 5 stock, and i sheared two of the 4 engine mount bolts right off. I am going to tap out the threads to accept a bigger diameter bolt...

Many scientists are asking as to why the universe appears to be "finely tuned". On the other hand some argue that the universe is the way it is because it is like winning a lottery. The odds of winning a lottery are very high but if one did win a lottery of odds such 1 in 12 million, one may...

ok certain notes have 3 strings. the rightmost string of a note loops around a peg and becomes the leftmost string of the next higher note. so if you increase the tension on the first, you have to increase the tension on the adjacent. right? well i thought so too, yet I've had 2 piano...

Tuning our bodys up as musical instruments helps tune up the universe. Just like we can't expect to go traveling to other dimensions until we keep our minds above negativity (breaking commandments). We can't even be galactically until we tune up our attitudes, and what a blessed world this...

hi: my questions says the following: A tuning fork labeled 392 Hz has the tip of each of its two prongs vibrating with an amplitude of 0.600 mm. What is the maximum speed of the tip of a prong? for this part i found omega= frequency*2pi then plugged that in V= omega*Amplitude, so my...

I'm writing up project on tuning forks and came across website: http://www.wrps.net/~dave_bergerson/labs/WaveSoundLight/Tones.doc which suggests that a tuning fork has a fundamental frequency that is different from the frequency stamped on the fork, due to some corrections due to its...
