♦ Wire of starting diameter = 3.0 mm is drawn to 2.5 mm in a die with entrance angle = 15° degrees. Coefficient of friction at the work- die interface = 0.07. For the work metal, K = 500 MPa and n = 0.30. Determine: (a) area reduction, (b) draw stress, and (c) draw force required for the operation.
