What Is the Correct Stress Calculation for a Wire Under Tension?

Click For Summary
SUMMARY

The correct stress calculation for a wire under tension is determined using the formula Stress = F/A, where F is the force applied and A is the cross-sectional area. In this discussion, the wire has a diameter of 0.35 mm and is subjected to a tension of 50 N. The calculated stress is approximately 3,242,542.153 Pa, derived from the area calculated using the diameter. The confusion regarding the wire diameter being 0.25 mm instead of 0.35 mm is clarified, confirming that the correct diameter is indeed 0.35 mm.

PREREQUISITES
  • Understanding of basic physics concepts, specifically stress and tension.
  • Familiarity with the formula for calculating stress (Stress = F/A).
  • Knowledge of how to calculate the area of a circle using the diameter.
  • Ability to convert units appropriately (e.g., mm to meters).
NEXT STEPS
  • Learn how to calculate the cross-sectional area of different shapes, such as rectangles and ellipses.
  • Explore the effects of material properties on stress calculations, including Young's modulus.
  • Study the implications of stress concentrations in engineering applications.
  • Investigate the relationship between tension and stress in various materials under load.

Homework Statement


Calculate the stress in a wire of diameter 0.35mm when the tension in the wire is 50N.


Homework Equations


Stress=F/A


The Attempt at a Solution


0.25/2=0.125
0.125/100=1.25x10"-3

Pi x 0.00125"2 = 1.542x10"-5

50/1.542x10"-5 = 3242542.153 Pa


Are my workings correct?
