The natural material in a borrow pit has a unit weight of 104 pcf and water content of 8%. The embankment will be compacted to dry unit weight of 117 pcf and water content of 11%. The geometric volume of the embankment is 160,000 CY. How many cubic yards of excavation (BCY) will be required to construct the embankment

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
