How to Determine the Original Length of a Steel Violin String Under Tension?

AI Thread Summary
To determine the original length of a steel violin string under tension, the problem requires calculating the string's elongation without using Young's modulus. The tension in the string is 83N, and its length under tension is 35cm. The cross-sectional area is provided as 0.2*10^-6 m^2. The discussion highlights the challenge of solving the problem without the modulus value, which is essential for calculating elongation. Ultimately, the original length cannot be accurately determined with the given constraints.

Hi I have a problem with the following question:

A steel violin string has a cross-sectional area of 0.2*10^-6 m^2 and is under tension 83N. If its length under tension is 35cm, find its original length.

I can not seem to solve the question without needing the value of young modulus...

That's correct, so look up Young's modulus for steel, the given material. It varies a bit amongst different grades of steels, but not by much.
 
Hi :)

I am supposed to find it using only the given information. Therefore I can not use Young's Modulus.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
