An integer number is said to be a perfect number if its factors, including 1 (but not the
number itself), sum to the number. For example, 6 is a perfect number, because 6 = 1 + 2 + 3.
Write a method perfect that determines whether parameter number is a perfect number.
Use this method in a java application that determines and displays all the perfect numbers
between 1 and 1000. Display the factors of each perfect number to confirm that the number is
indeed perfect. Challenge the computing power of your computer by testing numbers much
larger than 1000. Display the results.

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
