A copper wire has a length of 5.0 m and a diameter of 3.0mm. Under what load will it's length increase by 0.3 mm?© BrainMass Inc. brainmass.com March 4, 2021, 6:18 pm ad1c9bdddf
d= 3 mm= 0.003 m
Therefore Area = pi d^2/4= 0.00000707 m^2 =pi *0.003^2 / ...
The solution calculates the load under which the length of a copper wire increases by 0.3 mm.
