6. For a wire drawing operation, consider a friction coefficient of 0.1

6. For a wire drawing operation, consider a friction coefficient of 0.1 and a die with 2a = 10. Ignore redundant work while answering following questions: (a) Find the draw force needed for a 30% reduction of a 2 mm diameter annealed aluminum wire with K 180 MPa and n = 0.2. (b) If the wire is travelling at 2 m/s through the die, find the power required for the process described in (a). (c) Find the smallest diameter die that can be successfully used to draw the 2 mm diameter annealed wire described in part (a) accounting for friction. [10]
