How is a plumb bob used to check the vertical of a building under construction?
A plumb bob is a weight on the end of a string. It usually has a pointed lower end. It is hung adjacent to or in line with building elements to check whether they are "plumb" or "true to the vertical". A weight on a string holds the string under tension in a straight line down to the ground because of gravity. A person can move so they can see whether the straight line of the string lines up against the built element, to tell whether it is vertical.
What does factor strings mean?
Factor strings are multiplication sentences. 3 x 3 is a factor string for 9.
What is the length of a string to the nearest tenth of a centimeter?
Musical instrument strings: 4/4 Violin 32.7 to 33.0 cm Double bass 105.0 to 110.0 cm
Pythagoras discovered that to create the interval of a octave by stretching out two strings you need to play the second string using a ratio of 21?
Perfect
How many strings of lights needed to decorate a room that is 25.5 yards long and 32 yards wide if a string of lights is 5 yards?
A room that is 25.5 yards * 32 yards has a perimeter of 2*(25.5 + 32) = 2*57.5 = 115 yards. If each string of lights is 5 yards long, the number of strings required is 115/5 = 23.
A picture is supported by two vertical strings if the weight of the picture is 50N what is the force exerted by each string?
If a picture is supported by two vertical strings, then the force exerted on each string is 25N.
How does the sound of a guitar change when the strings are tightened and loosened?
the tension on the strings are what gives each string the "tone"
What is the properties of tennis strings?
there is a link. it tells u all the different strings. it also explains the string tension
What is 'brane tension'?
It's the tension of the strings in Superstring Theory. The tension refers to the ability of a string to vibrate at high or low frequencies, which is responsible for the energies of particles.
Why does putting pressure on a string in a stringed instrument make a different sound?
"Pressure" is not what causes strings to produce sound. It's "tension" which does that. Adjusting the tuners either increases or decreases the tension, thus altering the audible pitch. Bending the strings also increases the tension. The sound is due to the vibration of the strings. Greater tension causes a shorter, higher frequency wavelength or amplitude which produces a higher pitch. Lesser tension causes a longer, lower frequency wavelength which produces a lower pitch. Depressing the strings onto the fingerboard effectively shortens the length of the string. The more a string is shortened, the shorter its vibrational wavelength and the higher its frequency will become. The location along the fingerboard at which the string is depressed serves the same function as does the nut when a open string is sounded.
How do you test string tension of a tennis racket?
For ease, you can purchase a string meter or any other string tension meter that measures it for you. All you need to do is clip it between the strings and it will read the number in the display. If not, you can always use your hand and lightly tap the string bed to get an rough est. The harder it is the higher the tension and vice versa.
How does pendulum stops?
A pendulum stops, because it gradually looses its energy on friction force and tension of strings. Even on the moon, where there is no air to have friction with, it will still stop, though slower, because there is still friction with strings and the string's tension.
How is vibrations made on a guitar?
The strings vibrate by either using a bow (with a friction agent called Rosin on it ) or by pizzicato (plucking the strings with a finger). This vibration passes through the bridge and is then amplified by the belly and the back of the instrument via a sound post (viewed inside by looking through the "F" holes in the belly). The tone and volume are greatly affected by the quality of the wood and 'set-up' of the strings and bridge.
What three things are there of causing a string on a guitar to make a low note?
Thickness, length and tension are the main contributing factors in harmonic tone of a string. Materiel density (hardness), composition (such as wound strings vs. simple strings) how and where the string is struck and the acoustics of the instrument are also factors.
If you are using light strings on your parlor acoustic guitar can you replace your G string with a B string?
Yes it is. It is not recommended to do this all the time though, as each gauge string exerts different stress and tension on the guitar neck. It's best to do this only until you can get yourself new strings.
What force is on guitar strings?
I assume you mean tension. tension is a stretching force in am object (e.g. string). If you dangle a yoyo from your hand the string is being stretched by the weight of the yoyo. If the weight of the yoyo = 1N then the tension = 1N.
What are the factors that affect the sound of a vibrating guitar strings?
The factors of the sound of a guitar string are tuning the string (changes the tension; the tighter the higher) and pressing down on the fret (changes amount of string that vibrates; the shorter the higher)
