A metallic rod of 500 mm length and 50 mm diameter, when subjected to a tensile force of 100 kN at the ends, experiences an increase in its length by 0.5 mm and a reduction in its diameter by 0.015 mm. The Poisson's ratio of the rod material is _______
-
- 0.3
- 0.8
- 10
- 1
Correct Option: A
l = 500 mm, d = 50 mm, p = 100 KN
δl = 0.5 mm, δd = 0.015
Poission’s Ratio
 |  | = | ||
| m | longitudinal strain |
