A metal bar in axial tension has an axial strain of 0.0008 and a Poisson's ratio of 0.25. What is the magnitude of the lateral (transverse) strain?
- 0.0032
- 0.0002
- 0.0006
- 0.001
Answer
B. 0.0002
Solution
Lateral strain = × axial strain = 0.25 × 0.0008 = 0.0002 (opposite in sign to the axial strain).
