The induced drag generated on the wing of a cirrus jet is 210 n. the wing has a wing area of 17 m2, an aspect ration of 8.5 and a span efficiency factor of 0.8. the plane is cruising at 220 km/hr at sea level. determine the weight of the aircraft.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
