Problem $2$

In a turning operation seen in the below Figure, the following data were determined;

Compute the following:

a$)$ The coefficient of friction $\backslash ((\backslash$mu$)\backslash )$ of tool$-$chip interface

b$)$ The shear plane angle, $\backslash (\backslash$phi $\backslash )$; assuming the shear$-$angle relation of Ernest and Merchant applies.

c$)$ The stress on the shear plane
