Aviation Maintenance

newtons third law states that

• static friction causes a force

• every action has an equal and opposite reaction

• low velocity causes high pressure

• high velocity causes high pressure

kinetic friction is...

• the friction between two static objects (not moving)

• used to create power in the jet engine

• the friction force between two objects that are in motion (moving)

what are the four main forces that act on an aircraft?

• pull, drag, push and weight

• lift, thrust, mass and drag

• weight, pull, resistance and drive

• push, pull, weight and jump

steady state flight requires

• lift and mass to equal, thrust and drag to be equal

• acceleration to increase, with lift and thrust

• a large angle of attack

• for lift and drag to be greater

glide ratio is

• distance travelled / time taken

• altitude gained/ thrust

• altitide lost/ time taken

• distace travelled / altitude lost

supersonic speed is when an aircraft speed is

• mach < 1

• mach = 1

• mach >1

what is the relationship between thrust and lift force?

• thrust force increases the lift force

• thrust force contracts the lift force created

• thrust force is the opposite to lift force

• there is no relationship between them

what are the two main forces used for landing an aircraft

• thrust and lift

• drag and thrust

• mass and drag

• lift and mass

what is the sound of speed? (Mach 1)

• 769.1 km/h

• 986.3 km/h

• 1234.8 km/h

• 2315.2 km/h
