Question
A tensile test is performed on a brass specimen 10 mm in diameter using a gage length of 50 mm (see figure). When the tensile load P reaches a value of 20 kN, the distance between the gage marks has increased by 0.122 mm.
(a) What is the modulus of elasticity E of the brass?
(b) H the diameter decreases by 0.00830 mm, what is poison's ratio?
