The plane has centripetal acceleration in the horizontal direction. The pilot keeps the plane banked at just the right angle to keep the plane from slipping and maintain a steady altitude. Which forces, and which components of those forces, are keeping the plane from moving up or down?Visual1Up said:Need some suggestions...
I have a banked airplane at theta degrees, with a radius, and velocity. What is the formula for finding lift force. Fc = Fn sin theta I believe, but that's the only formula I am aware of. Thanks!,

Lift force is the upward force that is generated by an airplane's wings as it moves through the air. It is what keeps the plane in the air and counteracts the force of gravity.
Lift force is created by the shape of the airplane's wings, specifically the curvature on the top surface of the wing. This shape causes air to flow faster over the top of the wing, creating an area of lower pressure above the wing and higher pressure below it, resulting in lift force.
The main factors that affect lift force are the speed of the airplane, the angle of attack (the angle at which the wing meets the oncoming air), and the shape and size of the wing. Other factors such as air density, temperature, and altitude can also have an impact.
Lift force is not constant during flight and can change depending on the angle of attack and speed of the airplane. As an airplane takes off and gains altitude, the angle of attack decreases, resulting in a decrease in lift force. Similarly, during descent, the angle of attack increases, causing an increase in lift force.
Yes, lift force can be greater than the weight of the airplane. In fact, in order for a plane to take off and stay in the air, the lift force must be greater than the weight. However, during level flight, the lift force is equal to the weight, creating a state of equilibrium.
