Question

A force of 40 Newton is applied at the end of the wire 4m and produce an extension of 0.24mm if the diameter of the wire is 2.00 calculate the stress of the wire also calculate the strain of the wire

Answer 1

Explanation:

r = 10^-3 meters

stress = F/area = 40/ (pi r^2) = 40 /( pi * 10^-6)

strain = elongation/length = 0.24*10^-3 / 4

Young mod = stress/strain =
