When you are in an aeroplane does lift act in the opposite direction to friction?
Lift does not act opposite to friction. Lift opposes weight and friction(air resistance) opposes thrust from the engine. This is all equally true whether or not you happen to be aboard the aircraft. ...

What is the relationship between the 4 forces of flight?
Lift is opposite of weight Thrust is opposite drag. When lift >weight plane climbs. If lift < weight you best find a place to land. If thrust> drag you accelerate. If drag>thrust you slow down. High and fast are your friends. Low and slow are out to kill you. ...

How 2 cranes of 40 tons can lift in tandem one weight of 75 tons?
In practice, the cranes have to be "synchronized" which creates certain problems for controlling the lift. But as 40 + 40 = 80 there is ample overhead whentrying to lift 75 tons. The cranes would each lift opposite sides of the load at the same time. ...
How can oppose to a gravitational force?
If you are standing on the ground then the ground is opposing your weight due to gravity, with a reaction force equal to and opposite to your weight. If you are parachuting down at a steady speed then the air resistance from the parachute is equal and opposite to your weight. If you are in an airplane then the lift from the wings is equal and opposite to the total weight of the plane. ...
Asked in Physics
When you are standing on ground how much upward force exerted on you why does this force not lift u up?
Because there is an equal and opposite force pulling you down: gravity.
Asked in Inventions, Physics, Airplanes and Aircraft
What Parts of an airplane which provide lift and support entire weight of airplane?
The wings are the primary source of lift for an airplane. The horizontal stabilizer of most modern transport aircraft produces lift also, but the lift vector of the stabilizer is usually in the opposite direction (down) in order to keep the aircraft at the proper pitch attitude. Some aircraft configurations are designed so that the aircraft body itself provides lift. The Space Shuttle is an example of a "lifting body" aircraft. ...
Asked in Science
What is the Newtonian explanation and why is it not quite correct?
Newton's third law, stating every action has an equal and opposite reaction, describes lift. As air hits the wing from an opposing direction, it creates drag and lift results because of the third law. And I am not exactly sure why it is considered incorrect. ...

Can you install a block lift kit when the leaf springs are under the axle?
No, you will get the opposite effect. Some fabrication/welding needed to move the axle under the leaf springs, but it can be done. ...
