A 20.32-cm-diameter stainless-steel bar is being turned on a lathe at 600 rpm and at a depth of cut d = 0.254cm. If the power of the motor is 3728.4994 W and has a mechanical efficiency of 80%, what is the maximum feed that you can have at a spindle speed of 500 rpm before the motor stalls

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
