 Calculate the room-temperature forging force for a solid, cylindrical workpiece made of 5052- O aluminum that is 3.5 in. high and 5 in. in diameter and is to be reduced in height by 30%. Let the coefficient of friction be 0.15. Estimate the forging force for the workpiece, assuming that it is a complex forging and that the projected area of the ash is 30% greater than the projected area of the forged workpiece.  To what thickness can a solid cylinder of
