2/21/11 Chapter 6: stress strain concept For a bronze alloy, the stress at which plastic deformation begins is 275 Mpa, and the modulus of elasticity is 115 GPa 1. What is the maximum load that may be applied to a specimen with a cross-sectional area of 325 mm2 without plastic deformation?

2/21/11 Chapter 6: stress strain concept A brass alloy is known to have a yield strength of 275 MPa (40,000 psi), a tensile strength of 380 MPa (55,000 psi), and an elastic modulus of 103 GPa (15.0 ] 106 psi). A cylindrical specimen of this alloy 12.7 mm (0.50 in.) in diameter and 250 mm (10.0 in.) long is stressed in tension and found to elongate 7.6 mm (0.30 in.).
