A specimen of an alloy is made into a cylindrical bar of 12.00 mm diameter and 200.00 mm length. This bar is loaded in axial tension up to the proportional limit when the load is 40 kN. At this load the length was measured as 201 mm and diameter was measured as 11.98 mm. What will be the Poisson’s ration?

1.	A specimen of an alloy is made into a cylindrical bar of 12.00 mm diameter and 200.00 mm length. This bar is loaded in axial tension up to the proportional limit when the load is 40 kN. At this load the length was measured as 201 mm and diameter was measured as 11.98 mm. What will be the Poisson’s ration?
A.	0.25
B.	0.29
C.	0.33
D.	0.38
Answer» D. 0.38
