qustion(1):A rectangular face of a casting 250mmx100mm is to be machined on a sharper.if the average cuting speed is to be 20m/min and the feed is to be 2mm/stroke,calculate the time taken to machine the face of casting.allow 5mm overun at each end of the stroke.
question(2):two parallel resistor 32ohms an 24ohms are in a series with a 16ohm resistor.if a cell of 36volt with internal resistance of 40ohm is conected.calculate the current in each resistor.plz help i don,t even no were to start 4rm xplain tanx very much i nid it urgently
