- What can be determined when looking at the hardness values? What about when it comes to material wear properties?Determine the direction of slip line at the workpiece tool interface in the condition of coulombfriction when the value of COF is 0.2 and the normal stress is 100 N/mm^2?. The value of theshear yield strength is 84 N/mm^2?. Also explain the direction of slip line theory with coulombfriction.Describe the nature of the load and strength distributions in four practical engineering situations (use sketches to show the shapes and locations of distributions). Comment on each situation in relations to the predictability of failure and reliability, and in relation to the methods that can be used to reduce the probabilities of failure.
