36
Q

37
Q

Probability

A

Number of events wanted / total possible events

38
Q

Newton’s laws

A
  1. Every object in a state of uniform motion tends to stay in that state of motion unless an external force is applied to it.
  2. The relationship between an objects mass, it’s acceleration, and the applied force is F=ma. Acceleration and force are vectors; in this law the direction of the force vector is the same direction of the acceleration vector.
  3. Force exists only in pairs. Force acting on a body always elicits an equal, opposite force acting against it.
39
Q

Balancing a lever arm

A

Side A Force x length = Side B Force x length

40
Q

Boyle’s law

A

If a gas remains at a CONSTANT TEMPERATURE, the volume is INVERSELY proportional to the pressure. Thus compressing a gas to 1/2 it’s volume doubles the pressure.

41
Q

Charles’ law

A

If a gas is held at a constant pressure, the volume is DIRECTLY proportional to the absolute temperature. Thus heating a gas to double it’s original temperature doubles it’s volume.

42
Q

Bernoulli’s principle

A

As the velocity of a fluid increases, it’s pressure decreases.

43
Q

Ailerons control

A

Bank angle around longitudinal axis

44
Q

Elevator controls

A

Pitch around lateral axis

45
Q

Elevator up

A

Plane climbs

46
Q

Elevator down

A

Plane dives

47
Q

Rudder controls

A

Yaw around vertical axis

48
Q

Thrust

A

Forward force created by propeller or jet exhaust, counters drag

49
Q

Drag

A

Rearward force that counters thrust

50
Q

Lift

A

Force opposing gravity

51
Q

Gravity

A

Force opposing lift

52
Q

Four forces of flight

A

Thrust, drag, lift, gravity

53
Q

Density altitude

A

A measure of the combined effects of outside air temperature and air pressure compared to a normal temperature/pressure day

54
Q

Normal pressure/temperature day

A

15 Celsius and 29.92 inches of mercury

55
Q

Forms of drag

A
  1. Form/pressure drag (shape of aircraft or airfoil)
  2. Skin friction drag (solid and gas causing friction)
  3. Parasite drag = form drag + skin friction drag
  4. Induced drag (drag due to lift) created by vortices at the tip of the aircraft wing. Increases in direct proportion to angle of attack
