A 30-mm-wide and 40-mm-thick plate made of 6061-T6 aluminum is to be reduced to 30 mm in
one pass in a flat rolling operation. Roll radius = 350 mm, and rotational speed = 50 rev/min.
Determine (a) the minimum required coefficient of friction that would make this rolling operation
possible, (b) roll force, and (c) power requirement in W.
For 6061-T6 aluminum K = 410 MPa and n = 0.05.
