Question 1 of 21
1. Question
If force a is 30 kg and force b is 40 kg, what does the resultant force equal?
Correct
Incorrect
Hint
a squared + b squared = c squared

Question 2 of 21
2. Question
If force a is 50 kg and force b is 23 kg, what does the resultant force equal?
Correct
Incorrect
Hint
a squared + b squared = c squared
c squared = 3029
square root of 3029 = 55.03
c = 55.03 or 55 
Question 3 of 21
3. Question
If the resultant force is 50 kg and force b is 40 kg, what does force a equal?
Correct
Incorrect
Hint
a squared + b squared = c squared
a = square root of (c squared – b squared)
a = square root of (2500 – 1600)
a = square root of (900)
a = 30 
Question 4 of 21
4. Question
If lift is greater than weight, the aircraft will:
Correct
This question aims to teach you the relationship between weight and lift. It needs to be noted that you can get a question about an aircraft climbing when lift is less than weight. The reduction in lift has to be replaced by something to hold the aircraft in the air, in the case of a climb, it can be replaced by thrust, if sufficient thrust is available. eg: A jet fighter climbing vertical, or a aerobatic hanging off the prop.

5. Question
If lift is less than weight, the aircraft will:
Correct
This question aims to teach you the relationship between weight and lift. The principal in straight and level flight if you add lift, ie, hit a sudden headwind the aircraft will rise. If you suddenly get hit with less headwind you will descend. Be careful in the exams, these questions can be asked a lot of different ways. A great way to trick people who do not read the question properly.

6. Question
If lift is equal to weight, the aircraft will:
Correct
This is a really basic question, for beginners only, since it is in the sample area. As you do more reading you will understand there are more factors at play, eg, thrust, A of A, wing profile etc.

Question 7 of 21
7. Question
In basic terms, the relative airflow of an aircraft is always opposite the direction of motion.
Correct
Incorrect

Question 8 of 21
8. Question
For an aircraft that is climbing or descending, the relative airflow is parallel to ground level not the aircrafts direction of movement.
Correct
Always use an extreme example to work these out. Imagine in still conditions and you are flying vertically downwards at the ground. What direction is the airflow relative to the aircraft. The relative airflow would be vertically upwards. So the answer is: parallel to the aircrafts direction of movement (and in the opposite direction)

Question 18 of 21
18. Question
Total reaction on a wing is:
Correct
Incorrect

Question 19 of 21
19. Question
Lift is produced as a result of:
Choose the best response.Correct
High pressure wants to go to Low pressure which causes lift. The greater the pressure difference (angle of attack) the greater the lift, until the stalling angle of attack is exceeded.
Incorrect
High pressure wants to go to Low pressure which causes lift. The greater the pressure difference (angle of attack) the greater the lift, until the stalling angle of attack is exceeded.

Question 20 of 21
20. Question
To generate lift for a large (with MTOW > 5700 kg)aircraft the pressure difference above and below the wing needs to be many multiples of that required for a small (with MTOW < 5700 kg) aircraft, irrespective of wing size.
Correct
Incorrect

Question 21 of 21
21. Question
When total reaction is worked out, it takes into account pressure on both the upper and lower sections of the wing. There becomes a point around which all pressure is evenly distributed, known as:
