1. Consider a cylindrical nicked wise of 4.0 mm in diameter and 200 mm long. The elastic modulus of the Ni wire is 207 X 1 N/m / 207 x 103 N/mm?), when the load off 400 N is applied. Assume that the deformation is totally elastic. a) Calculate the tensile strain and the elongation of the wire ( displacement / deformation along the tensile direction) 6 Given that the wise's poisson's ratio is 0. 3, calculate the lateral strain and change the width of the wire ( the wire should Shrunk along the lateral direction .). () After releasing the lead, what happens to The length and width of the wire
