7- Question 7. For the material of problem 6, calculate rolling force and torque in flat-rolling process. Estimate rolling force and power for the material of problem 4 as a metal strip of 200 mm wide and 10 mm thick, rolled to a thickness of 6 mm. The roll radius is 200 mm, and the roll rotates at 200 rpm; use = 0.1. (4 marks) 7- Question 7. For the material of problem 6, calculate rolling force and torque in flat-rolling process.
