In a multi-pass operation, a round bar of 10 mm diameter and 100 mm length is reduced in cross-section by drawing it successively through a series of seven dies of decreasing exit diameter. During each of these drawing operations, the reduction in cross-section area is 35%. The yield strength of the material is 200 MPa. Ignore strain hardening.
