Answer
$σ_{y} = 0.96 MPa$
Work Step by Step
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,
$σ_{y} = 2τ_{crss} = (2)(0.48 MPa) = 0.96 MPa$
