b. A round rod of aluminium is being drawn from a diameter of 4 mm to 3 mm at a speed of 1 m/s Assume that the frictional and redundant work together constitute 55% of the ideal work of deformation. Assume K= 205 MPa and n= 0.20
i. Calculate the power required in this operation, and
ii. calculate the die pressure at the exit of the die
