A piece of lead 25 mm x 25 mm x 150 mm, with a yield stress 7 MPa, is forged between flat dies to a final aproximate size: 6 mm x 104 mm x 150 mm. Assume that a friction coefficient p = 0.25 prevails with sliding between the lead and the full width of the dies in the contact region. Determine the pressure distribution that the dies exert upon the lead and the total fbrpng force required.
