Problem (5) A 140 lb pilot of an airplane executes a vertical loop which in part follows the path of a "four-leaved rose" = (−400 cos 2thetatheta) ft, where thetatheta is measured in radians. If the pilot experiences weightlessness at point A while flying at a constant velocity, determine the speed of the airplane. Does your answer depend on the weight of the pilot?

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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
