Wire stretch? Young's modulus? | Yahoo AnswersOct 28, 2009 · A mass of 44 kg is suspended from a steel wire of diameter 1.3 mm and length 2.3 m. How much does the wire stretch in mm? Young's modulus for steel is 2.0 x 10^11 N/m^2. 4 AnswersOk so first get the equations sorted. You know Young modulus (E) = Stress/strain.Stress is calculated by Force (F)/Area (A)Strain is extension...Best answer · 2Young Modulus Of Steel Wire0For the best answers, search on this site https://shorturl.im/axA5Yprobably in this case it's better to play with the definition of Young's modul...0Mike just focused on the math.

### Strain and Stress help? | Yahoo Answers

Sep 22, 2010 · Area = pi* (.001m)^2 = 3.14159 x 10^-6. Stress = 46.8 MPa or .0468 GPa. 200 = .0468/strain. strain = .000234. Strain = delta L/L. .000234 = delta L/3.5. delta L = .00082 m.

### Explain why a long thin wire is used in the Young modulus wire stretch? young s modulus? yahoo answers

Dec 18, 2012 · Obviously a long wire can be easily pulled straight with minimum of plastic strain but a 5cm diameter metal bar cannot.Other practical reasons include the facts that readings of change in gauge length and change in stress can only be reliably made when the wire is straightened out(no kinks).So from that point onwards change in stress /change in load is entirely due to elastic extension. extensEngineering Physics _ Young's Modulus? | Yahoo AnswersJul 24, 2014 · A steel cable with cross-sectional area 3.00 cm2 has an elastic limit of 2.40×108 N/m2. Assuming the cable is not stretched, find the maximum upward acceleration that can be given an elevator of mass 1300 kg supported by the cable if the stress is not to exceed one-third of the elastic limit. Youngs Modulus of steel is 2.00 x 1011 N/m2 and acceleration due to gravity is 9.81 m/s2All categories - Yahoo Answers UKDec 08, 2012 · Favourite answer. Young modulus = tensile stress / tensile strain = (F / A) / (L / L) = FL / AL. where: F = Force exerted = 500 newtons. A = Cross-sectional area to which the force is
