The fulcrum is at one end of the lever and the weight or resistance to be overcome is at the other end, with effort applied at some point between.
Meaning to occupy space
What are the advantages of a wet sump system, compared to a dry sump?
A wet sump is attached to the bottom of the case, it is integral and complete, requiring no external parts and fittings to complicate installation and maintenance
No second (scavenge) pump is required
Chance of oil pump failure us reduced
This system can be operated in much colder ambient temperatures w/o concern that the oil congeal in the external lines
quantity which is useful when describing matter, especially when in the liquid or gaseous state
Newton 3rd law
for every action there is an equal and opposite reaction
has neither a definite volume nor a definite shape.
What is the relationship between aviation grade number and SAE numbers for lubricating oil?
Society of Automotive engineers divides all oils into groups according to viscosity at either 130F or 210F
Whagt forces are used to feather a propeller?
Resistance to motion is greatly reduced if an object is mounted on wheels or rollers
Prevents the escape of gas past the piston during engine operation
Has a definite volume, but they take the shape of the containing vessel.
measure of the inertia of a body, and therefore is a measure of the quantity of matter associated with the body
Liquid cooled and air cooled with even number of cylinders. two in-line banks generally 30-60 degrees apart
What distinguishes a liquid from a gas?
Liquid has a definite volume, but they take the shape of the containing vessel. Gases not only take the shape of the containing vessel, but they expand and fill the vessel, no matter what it's volume
The useful output of all aircraft powerplants is the
A feathered propeller will have a blade angle of approximately how many degrees?
four-stroke cycle is?
Intake, compression, power, exhaust
The indicated horspower minus the brake horsepower
What is the function of an augmenter tube?
Provide additional cooling airflow, especially for low speed, high power conditions (Climb)
How does opening cowl flaps affect engine cooling? Cabin cooling?
Open cowl flaps increase cooling over the engine and through the oil cooler
Hot and cold airflow into the cabin is reduced in most single engine installations due to reduced aur pressure inside and in front of the cowling when the cowl flaps are open
a force that results from the characteristic of particles of matter that causes attraction or pull on other particles of matter
Prevent leakage of gas pressure from the combustion chamber and reduce to a minimum the seepage of oil into the combustion chamber
What is Force X Distance
How are the cylinder walls lubricated in a typical opposed engine?
Oil sprayed from the crankshaft and crankpin bearings
How does the cowling contribute to the engine cowling?
Designed to force air over the cylinder cooling fins
The foundation of an engine.
The rate of doing work or the terms of work accomplished per unit of time
