## Materials Science and Engineering: An Introduction

$σ_{y} = 0.96 MPa$
Given: The critical resolved shear stress for copper (Cu) is 0.48 MPa (70 psi) Required: Determine the maximum possible yield strength for a single crystal of Cu pulled in tension Solution: Using Equation 7.5, $σ_{y} = 2τ_{crss} = (2)(0.48 MPa) = 0.96 MPa$
