Problem- Normal strain and Poisson's ratio
A tensile test is performed on a brass specimen 10 mm in diameter using a gauge length of 50 mm. When the tensile load P reaches a value of 20 kN, the distance between the gauge marks has increased by 0.122 mm.
(a) What is the modulus of elasticity E of the brass?
(b) If the diameter decreases by 0.00830 mm, what is Poisson's ratio?
Additional information-
This problem related to Mechanical Engineering and it is about computing probability of a batch of brass specimens for tensile strength under Poisson's and normal ratio. The solution has detailed calculations.
