1) A hydraulic cylinder is used to lift a 6000 Ibs load straight up 1 foot in 2 seconds. The bore diameter of the cylinder is 3.5 in. The maximum system pressure is 1000 psi. A hydraulic pump that runs at 1750 rpm is used to provide the required flow rate. Assuming the pump has a volumetric and total efficiency of 85% and 80%, respectively, calculate a) the actual and theoretical pump delivery (gpm). (7 points) b) the pump volumetric displacement (in3 /rev). (3 points) c) the maximum power input to the pump (hp). (5 points

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
