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

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
