A 40-mm-thick plate was rolled down to 30 mm in one pass. The entrance speed was 16 m/min. Roll radius was 300 mm, and the mill was running at a speed of 18.5 m/min.. Determine:1. The minimum required coefficient of friction 2. The exit velocity, if the plate width increases by 2%3. Forward slip

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
