Define Vector - Answer-A quantity that expresses both magnitude and direction. A vector quantity is represented by an arrow that displays direction and has a length proportional to magnitude Moment - Answer-Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") Equilibrium Flight - Answer-When the sum of all FORCE and all MOMENTS around the COG are equal to zero When are the four forces that ac...

Define a vector - Answer-magnitude and direction ex) displacement, velocity, acceleration or foce Define a moment - Answer-A tendency to cause rotation around a point. (F x d). Also called torque. Define moment arm - Answer-Perpendicular distance from the line of action of the force to the fulcrum State the requirements for an airplane to be in equilibrium flight - Answer-Equilibrium flight exists when the sum of all forces and the sum of all moments around the CG are equal to zero. ...
