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

Click For Summary
SUMMARY

The discussion centers on calculating the original length of a steel violin string under tension without using Young's modulus. The string has a cross-sectional area of 0.2 x 10^-6 m² and is under a tension of 83N, with a length of 35cm when tensioned. Participants emphasize that Young's modulus is essential for accurate calculations, but the original poster insists on solving the problem using only the provided information, highlighting a common challenge in material mechanics.

PREREQUISITES
  • Understanding of tensile stress and strain concepts
  • Familiarity with the properties of materials, specifically steel
  • Basic knowledge of mechanical properties, including Young's modulus
  • Ability to perform calculations involving cross-sectional area and tension
NEXT STEPS
  • Research the properties of different grades of steel and their Young's modulus values
  • Learn about tensile strength and its implications in material science
  • Explore the relationship between tension, length, and cross-sectional area in strings
  • Study the principles of elasticity and how they apply to real-world materials
USEFUL FOR

Students and professionals in mechanical engineering, materials science, and physics who are dealing with problems related to material properties and tension in strings.

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.
