A picture of weight 25N hangs from a hook by two strings which each makes an angle of 35 with the vertical .What is the tension in each string?
To find the tension in each string, we can use the concept of equilibrium. The vertical components of the tension in both strings must equal the weight of the picture (25 N). Since the angle is 35 degrees, the vertical component of the tension ( T ) in each string is ( T \cos(35^\circ) ). Therefore, the equation becomes ( 2T \cos(35^\circ) = 25 ). Solving for ( T ) gives ( T = \frac{25}{2 \cos(35^\circ)} \approx 21.5 , \text{N} ).

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.
Using 2 pieces of string stretched to the same tension Pythagoras?
When two pieces of string are stretched to the same tension, they can form a right triangle if they are arranged at angles to each other. Using Pythagoras' theorem, the resultant tension in a direction can be calculated by treating the two tensions as perpendicular vectors. The formula ( R = \sqrt{T_1^2 + T_2^2} ) can be applied, where ( T_1 ) and ( T_2 ) are the tensions in the strings. This allows for the determination of the overall tension and direction of the combined forces acting on the system.
What does factor strings mean?
Factor strings are multiplication sentences. 3 x 3 is a factor string for 9.
Using two pieces of string stretched to same tension Pythagoras discovered the ratio for creating perfect octave was?
Pythagoras discovered that the ratio for creating a perfect octave is 2:1, meaning that when the length of one string is half that of another, the higher pitch produced corresponds to an octave above the lower pitch. This finding highlighted the mathematical relationship between string length and frequency, illustrating how tension and vibration contribute to musical harmony. Thus, when two strings are stretched to the same tension, their lengths determine the musical intervals they create.
Using two pieces of string strectched to the same tension phytogaras discovered the ratio for creating interval of a perfect octave was?
Pythagoras discovered that the ratio for creating an interval of a perfect octave is 2:1. This means that when one string vibrates at a frequency of a certain pitch, the string that is an octave higher vibrates at double that frequency. By using two strings of the same tension and varying their lengths, he found that shortening the string to half its length produces this harmonious interval. This principle laid the foundation for understanding musical harmony and the mathematical relationships between musical notes.
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.
Can you put steel strings on a nylon string guitar?
No, it is not recommended to put steel strings on a nylon string guitar as it can damage the instrument. Nylon string guitars are designed to handle the lower tension of nylon strings, while steel strings require a higher tension that can potentially warp the neck or damage the bridge of a nylon string guitar.
What is the importance of the guitar string key in maintaining the tension and tuning of a guitar string?
The guitar string key is important for adjusting the tension of the guitar strings, which helps to keep the strings in tune. Turning the key tightens or loosens the strings, allowing the player to tune the guitar accurately.
What are the best practices for changing and maintaining the tension of guitar strings from top to bottom?
To change and maintain the tension of guitar strings from top to bottom, it is best to tune the strings gradually and evenly, starting from the thickest string (top) to the thinnest string (bottom). Use a tuner to ensure each string is at the correct pitch. Avoid sudden changes in tension to prevent damage to the guitar or strings. Regularly check and adjust the tension to keep the guitar in tune and prevent string breakage.
Can I put nylon strings on my steel string guitar?
No, it is not recommended to put nylon strings on a steel string guitar as the tension and construction of the guitar may not be suitable for nylon strings.
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 are the recommended string gauges for a 12-string guitar?
The recommended string gauges for a 12-string guitar are typically lighter gauge strings for the higher octave strings and heavier gauge strings for the lower octave strings. This helps to balance the tension and ensure proper tuning and playability.
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 are the best techniques for changing and maintaining the tension of guitar strings 1-6?
The best techniques for changing and maintaining the tension of guitar strings 1-6 involve using a string winder to efficiently change strings, tuning the strings regularly to maintain proper tension, and avoiding extreme temperature changes that can affect the tension of the strings.
What determines the pitch in a string instrument?
The pitch of a string instrument is determined primarily by the string's length, tension, and mass. Shorter strings, higher tension, and lighter mass result in higher pitches, while longer strings, lower tension, and heavier mass produce lower pitches. Additionally, the material of the string and how it is played (e.g., plucking or bowing) can also affect the pitch produced.
