A5-in. diameter, gray cast iron cylindrical part is to be turned on a lathe at 500 rpm. the depth of cut is 0.25 in. and the feed is 0.02 in./rev. what power (hp) is required for this operation? assume that the energy requirement for machining cast irons is 2.0 hp. min/in3 . [hint: the power (hp) = energy per unit vol. multiplied by mrr].

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
