Construct a Merkle tree out of the following four data items: "reserved" "volts" "with" "phantom". Use the same process as we did in class exercise, using hex hashes as strings rather than numbers in subsequent hashes, concatenate without separators, and use lower case hash strings, and be careful of

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
