Question:
The maximum takeoff mass for a Boeing 777-300ER passenger jet is 3.5 × 105 kg. The plane’s wing area is about 440 m2. Compute the average air pressure on the plane’s wings required to overcome the plane’s weight and lift the plane off the ground. How far does this pressure deviate from average atmospheric pressure at sea level? Repeat the calculation for a Lear jet with mass 3300 kg and wing area 21.5 m2. Comment on the implications for the assumption that air behaves as an incompressible fluid in these situations.
Step by Step Answer:
Pressure is force per unit area The force of gravity can ...View the full answer

As we know, to break a coconut we have to apply 400 pounds of pressure to it. In pounds = 400psi In newton = 1779.29N Starting from the first person he will try to break the coconut with his hands. As we know humans can exert a force 292 newtons by their hands. So force by hand is approximately = 300 N Then the second and third one also try to break it by hand but they fail too.
