A cylindrial workpiece is subjectef to a cold upset forging operation the starting piece is 3 in. In height an 2 in. in diameter it is reduced in the operation to a height of 1,5 in. The work material has a flow curve defined by K= 50.000 lb/in^2 and n= 0,17. Assume a coefficient of friction of 0,2 determine the face as the process begins at intermediate height of 2,5 in and 2 in and the final heights of 1,5 in
