At the proportional limit, a 2-in. gage length of a 0.375-in.- diameter alloy rod has elongated 0.0083 in. and the diameter has been reduced 0.0005 in. The total tension force on the rod was 4.75 kips. Determine the following properties of the material:
(a) the modulus of elasticity
(b) Poisson’s ratio
(c) the proportional limit
