A metal bar in axial tension has an axial strain of 0.001 and a Poisson's ratio of 0.3. What is the magnitude of the lateral (transverse) strain?
- 0.003333
- 0.0007
- 0.0003
- 0.0013
Answer
C. 0.0003
Solution
Lateral strain = × axial strain = 0.3 × 0.001 = 0.0003 (opposite in sign to the axial strain).
