# Exercise: Determination of the critical resolved shear stress for slip in cadmium

The following sequence of images shows slip in a cadmium crystal after deformation to 40 % and 100 % of its original length. By measuring the angles φ and λ at each stage of deformation, the slip geometry relationships
*l*_{0} cos φ_{0} = *l*_{1} cos φ_{1} and *l*_{0} sin λ_{0} = *l*_{1} sin λ_{1} can be tested.
