a. Describe the drawing operation. How bar drawing is different from whe drawing. [3] b. A round rod of annealed steel is being drawn from a diameter of $5\mathrm{mm}$ to $3\mathrm{mm}$ at a speed of $0.8\mathrm{m}/\mathrm{s}$ Assume that the frictional and redundant work together constitute $50\%$ of the ideal work of deformation. Assume $\mathrm{K}=760\mathrm{MPa}$ and $\mathrm{n}=0.19$ [3] i. Calculate the power required in this operation, and ii. calculate the die pressure at the exit of the die
