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"
If M what is the tension in string 1?
To determine the tension in string 1, you would need to know more information about the forces acting on the strings and the specific setup of the system. The tension in string 1 will depend on factors such as the mass of the objects being connected by the string, the angles at which the strings are pulling, and any other forces involved in the system.
What is the properties of tennis strings?
there is a link. it tells u all the different strings. it also explains the string tension
Why the vertical speed of a horizontal taut string depend on the wave speed?
The vertical speed of a horizontal taut string depends on the wave speed because the tension in the string is responsible for transmitting the wave along its length. The wave speed is determined by the tension in the string and the properties of the medium it is traveling through, which in turn affects the vertical motion of the string as the wave propagates.
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.
How much tension is in 20 newtons of apples?
Tension refers to the force applied by a string, rope, or cable. The tension in 20 newtons of apples would depend on how the apples are hanging or suspended. If the string supporting the apples is vertical, then the tension in the string would also be 20 newtons.
When in a simple pendulum is the string tension greatest least?
The string tension is greatest at the lowest point of the pendulum swing, where the mass is at its lowest position and experiences the highest acceleration. The tension is least at the highest point of the swing, where the string is almost vertical and the force of gravity is mostly perpendicular to the string.
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 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.
If you change the length of the string will it make the frequency increase or decrease?
Changing the length of a string will affect its frequency. Shortening the string will increase the frequency, while lengthening the string will decrease the frequency. This is because shorter strings vibrate more quickly, producing higher pitches, whereas longer strings vibrate more slowly, resulting in lower pitches.
