Answer 1

F=ma
W=Fd

P=F*d/t = Force Speed

Rotating objects;
Power = Torque * RPM 2pi/60

Question 7

Mixture
Mass or volume?

Answer 7

Mass

Question 8

Detonation neden olur?

Low octane
High EGT
High Cylinder Head Temperature

Question 9

Primer pump
Ilk yakıtı gönderen pompa

Excessive should be avoided
Risk of engine fire
Risk of flooding the engine
Fouling of the spark plug

Question 10

Detonation

High CHT
Using too lean mixture
Low octane fuel

Question 11

Pre-Ignition

Answer 11

Mixture ignited by abnormal condition within cylinder before spark occurs - hot spot.

Question 12

Venturi’de throttle valve - sıcaklık düşüyor
Bundan dolayı buzlanma olabilir.

Question 13

Diffuser

prevents mixture becoming too rich with increasing rpm

Question 14

Mekanik olarak motora bağlı ekipmanlardan bazıları:
Yağ pompası
Yakıt pompası
Vacuum pompası (for gyroscopic equipments)
Alternator
Magneto

Question 15

Magneto;

Rotating magnet
High tension system
Aircraft independent

Answer 15

Motora bağlı olduğu için ve dönen mıknatısla elektrik ürettiği için uçaktan bağımsız.

Question 16
