Experimentally, it has been observed for single crystals of a number of metals that the critical resolved shear stress is a function of the dislocation density, ρD:

where
and A are constants. For copper, the critical resolved shear stress is 2.10 MPa at a dislocation density of 105 mm−2. If it is known that the value of A for copper is 6.35 × 10−3 MPa·mm, compute the critical resolved shear stress at a dislocation density of 107 mm−2.
