A cylindrical rod undergoing tensile strain within its elastic limit experiences a volume change. If the volumetric strain equals half the tensile strain, the rod's Poisson’s ratio is___________________?
Show answer Hide answer
Answer: C. 0.44
Explanation
Volumetric strain is related to linear strain and Poisson's ratio v by epsilon_v = epsilon * (1 - 2v). Given epsilon_v = 0.5 * epsilon, solving gives v = 0.25.
