Final answer:
The maximum thickness of a conventional wing is typically located 30-50% of the way from the leading edge. Airspeed above the wing must be higher than at the bottom to create lift, following the principle that 1000 N of lift is needed per square meter.
Step-by-step explanation:
A conventional wing will have its maximum thickness located at around 30-50% of the chord from the leading edge. This position helps the wing produce favorable aerodynamic characteristics such as lift and stability. During lift-off, the airspeed relative to the bottom of the wing at 60.0 m/s requires the air to move faster over the upper surface to decrease pressure and generate lift.
By using Bernoulli's principle and the rule of thumb that wings should produce about 1000 N of lift per square meter, we can estimate the required airspeed over the wing's upper surface. However, this rule is a simplification, and actual wing performance is influenced by factors such as the wing's shape and aspect ratio, as well as the aircraft's design and operational conditions.
