A cylindrical specimen of a nickel alloy having
an elastic modulus of 207 GPa (
psi) and an original diameter of 10.2 mm
(0.40 in.) will experience only elastic deformation
when a tensile load of 8900 N (2000 lb )
is applied. Compute the maximum length
of the specimen before deformation if the
maximum allowable elongation is 0.25 mm
(0.010 in.).
