P4 (20pts). The following data are available from orthogonal
cutting experiments. In both cases depth of cut (feed) $t = 0.10$
mm, width of cut $w = 2.4$ mm, rake angle $= -5^\circ$, and cutting
speed $V = 2.0$ m/s.
Determine the shear angle, friction coefficient, shear stress
and shear strain on the shear plane, chip velocity $V_c$ and shear
velocity $V_s$.
