Jeppesen Oral- Chapter 2 (Physics) Flashcards
Anything with mass
Solid, gas, liquid
Energy of motion
Force and displacement
Rigid bar and a pivot point called a fulcrum
Second class lever
All three are affected with gas being the most affected
The amount of heat energy required to change the temperature of 1 pound of water 1 degree Fahrenheit
Conduction, convection and radiation
Absolute zero
Generally speaking, no
Pounds per square inch
Pressure is transmitted equally in all directions
F= A X P
661 knots, 343 mps, 767 mph
29.92 inch mercury, 14.7 PSI, 1013.25 HP
59F or 15C
Temperature and atmospheric pressure
Relative humidity
Lift, drag, weight, thrust
The angle of attack
Exceeding the critical angle of attack which causes boundary layer seperation
decreased stall speed, increased lift (up to point) and increased drag
Delay boundary layer separation by re-energizing the boundary layer with kinetic energy
Increases the AoA and lift of the retreating blade and decreases the angle of attack and lift on the advancing blade
Normal flight- air moves downwards Auto-rotation- air moves upwards
Opposition to relative motion between two objects in contact
Force that acts on a unit area
Its temperature
The weight of a given volume of air.
20,000 pounds
The point about which the lever rotates
First-class: A screwdriver being used to pry the lid from a can of paint. Second-class: A wheelbarrow Third-class: A shovel
100 cubic inches
10 degrees Celsius
The number of ropes that support the weight.
The ratio between the number of teeth on the drive gear and the number of teeth on the driven gear.
pressure will increase
The actual amount of water that is in a given volume of air.
°C * 1.8000 + 32.00
°F - 32/ 1.8000
