-Format: Multiple-choice / Flashcard
Question 1: Newton
Answer:
The SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second
Question 2: Spring scale
Answer:
A spring scale can be used to measure all kinds of force. basically, it measures the force pulling on its shackle
Question 3: Newton's third law of motion
Answer:
For every action there is an equal and opposite reaction
Question 4: Skin friction
Answer:
Drag caused by the friction of a fluid against the surface of an object that is moving through it
Question 5: Equilibrium
Answer:
A state in which opposing forces or influences are balanced
Question 6: Gravity
Answer:
The force that attracts a body toward the center of the earth, or toward any other physical body having mass
Question 7: Energy
Answer:
Ability to do work, which is the ability to exert a force causing displacement of an object
Question 8: Trailing edge
Answer:
Where the airflow that came over the upper surfaces rejoins the lower surface first
Question 9: Bemouli's Principal
Answer:
The principle of energy conservation for ideal fluids in steady, or streamline flow. (basis for many engineering applications
Question 10: Elastic recoil
Answer:
When you exert a force on a solid object, it responds by exerting an equal force in the opposite direction
Question 11: Force
Answer:
Something that changes the velocity of an object by making it start, stop, speed up, slow down, or change direction
Question 12: Lift
Answer:
Aerodynamic force produced by the motion of a fluid past an object
Question 13: Viscous drag
Answer:
The drag force felt by an object moving through a fluid due to the viscosity of the fluid
Question 14: Dry friction (Coulomb friction)
Answer:
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other
Question 15: Newton's second law of motion
Answer:
The acceleration of an object depends on the mass of the object and the amount of force applied.
Question 16: Newton's first law of motion
Answer:
An object in motion will remain in motion unless acted upon by another force
Question 17: Fluid friction
Answer:
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other
Question 18: Work
Answer:
Mechanical work is the amount of energy transferred by a force
Question 19: Leading edge
Answer:
The part of the airfoil that meets the airflow first
Question 20: Tension
Answer:
The force transmitted by a rope, string, or wire when force is applied to both ends
Question 21: Mass
Answer:
The quantity of matter in a particle or object. (measured in kilograms)
Question 22: Power
Answer:
Power in mechanical systems is the combination of forces and movement
Question 23: Gears
Answer:
Two or more wheels linked together by interlocking teeth
Question 24: Camber
Answer:
A measure of the curvature of the airfoil
Question 25: Downwash
Answer:
Downward airstream deflection as it passes over the wing and past the trailing edge
Question 26: Buoyancy
Answer:
The ability or tendency to float in water or air or some other fluid
Question 27: Weight
Answer:
The force of gravity (directly proportonial to the acceleration of an object due to gravity.) (measured in newtons)
Question 28: Sliding friction
Answer:
A force that is generated whenever two objects are in contact and there is relative motion between them
