a=2  b=5

3xb=15x mm   12xb=60x mm

10xa kN = 20x kN 

((3xb)-0,00735))  = (15x- 0,00735)  mm

Question 3
(MPa)
The elastic portion of the stress-strain diagram for a steel
alloy is shown in the figure. The specimen from which it was
obtained had an original diameter of 3xb mm and a gauge
length of 12xb mm. When the applied load on the specimen
is 10xa kN, the diameter is [(3xb)-0.00735] mm. Determine
Poisson's ratio for the material.
