Final answer:
The weight of a plane and lift are two different forces. A plane needs wings with a specific area to generate the necessary lift to counteract its weight.
Step-by-step explanation:
The weight of a plane is the force exerted by gravity on the plane. Lift, on the other hand, is the force that opposes the weight of the plane and allows it to fly. The amount of lift needed to counteract the weight of a plane depends on several factors, including the size and shape of the wings and the speed of the plane.
In aircraft design, a commonly used rule of thumb is that wings should produce about 1000 N of lift per square meter of wing area. So, if a plane weighs 60000 N, it would need wings with an area of 60 square meters to generate the required lift. This value can then be used to design and construct the wings of the plane to ensure it can take off and fly successfully.
