Is the double wedge airfoil design used for flying above or below the speed of sound?

What is the back edge of an airfoil called?

The straight line distance between the leading edge and the trailing edge is called the?

This is the angle of?

A symmetrical airfoil has zero?

Camber and angle of attack have a large influence on the amount of lift an airfoil will generate?

What type of stress is this?

what type of stress is this?

The orange area represents?

The blue area represents?

Does the high pressure below the airfoil or the suction generated by the low pressure above the airfoil generate more lift?

Without a difference in air pressure above and below the wing there can be no lift?

Newton's Third Law tell us?

According to Newtons Third Law (for every action there is an equal and opposite reaction) an airfoil generates lift by turning the incoming air downwards?

Increasing the camber of an airfoil will increase the amount of fluid it can deflect and in result increase the lift force?

If the angle of attack is raised too high will it decrease lift?
