Generally, lift is created when the pressure below an object is greater than the pressure above it. For example: an airplane wing is curved on top to allow for air to seamlessly pass over, creating low pressure on the upper surface and the wing is obstructed on the bottom, creating higher pressure to lift the wing. As for a helicopter, the air is pushed down by the propeller, causing high pressure below the rotation plane, causing lift.
An average 3 ton mini excavator will lift approx 1400kg, almost half the weight of the machine as a general rule of thumb
The 4 main forces of flight are: drag, thrust, lift and weight
It was made by John W. Parker in California.
If that wing is turned upside down, it increases drag instead of lift. Race cars use this increased downward force to give them more traction at higher speeds.
Because air drag and flow is what gives the wings lift. Air travels faster under the wing and slower over top the wing. This creates less pressure on the top of the wing providing 'lift'.
