A copper wire has a length of 5.0m and a diameter of 3.0 mm. Under what load will its length increase by 0.3 mm. (If you need Young's Modulus (Y) for copper it is 11 x 10^10N/m^2.)© BrainMass Inc. brainmass.com September 23, 2018, 4:19 am ad1c9bdddf - https://brainmass.com/physics/classical-mechanics/question-about-solids-elastic-moduli-38911
The solution provides a few quick lines of calculation using the relevant theoretical formula to reach the answer of what load will increase the length of a certain copper wire by 0.3m.
