A brass alloy rod having a cross sectional area of 100 mm2
and a modulus of 110 GPa is subjected to a tensile load. Plastic deformation was observed to begin at a load of 39,872 N.
a. Determine the maximum stress that can be applied without plastic deformation.
b. If the maximum length to which a specimen may be stretched without causing plastic deformation is 67.21 mm, what is the original specimen length?
