A strip is 300 mm wide and 30 mm thick is rolled to a thickness of 20 mm in one pass. The roll radius is 200 mm, and the rolls rotate at 200 rpm. If the rolling die can exert 500 kW of power for this operation. Find the possible strip material(s) if the strain hardening exponent is assumed to be 0.2.

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?
