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

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
