Unformatted text preview: ‘ ME 467 Exam 1 Fall 2017 NAME: 22. Your goal is to roll steel plate from an initial thickness of 40 mm down to 35 mm. Your rolling process for the steel plate produces u = 0.10. The rollers operate at 50 rev/min. As the thickness is reduced, the plate Widens by 4%. Yield strength of the steel = 174 MPa, and tensile strength = 300 MPa. The entrance speed of the plate = 60 m/min. Determine the Roller diameter required to accomplish the reduction in thickness in one pass, based upon friction produced. 4pt h l 3&quot; 44.. r . m I? ﬂmiﬁm 5; Maw“ K C M \Q' 1:: fOﬂ MM Page 11 of 13 ...

• Summer '19

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
