A parachute designer is task with designing a round parachute for a human that weighs 160 lbs. The user wants to descend at a rate of 4.5
meters per second. Given that the coefficient of drag is .75 and the
air density is 1.22 kilograms per cubic meter. What is the area in
meters squared of the parachute that the designer will have to
construct?

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
