Quiz 8
Test Your Knowledge on Fluid Dynamics
Welcome to the Fluid Dynamics Quiz! This engaging quiz will challenge your understanding of the principles governing lift, buoyancy, and drag in fluid motion. Test your knowledge with 10 thought-provoking questions that cover key concepts and applications.
Whether you're a student, educator, or simply an enthusiast, this quiz is designed to enhance your comprehension of fluid dynamics.
- Explore the forces acting on submerged bodies
- Understand the principles of lift and drag
- Challenge yourself with practical scenarios
The principle or law used to describe lift is called:
Archimedes' principle
Wolff's principle
Pascal's principle
Newton's Principle
Bernoulli's principle
The vertical force that always acts vertically on an immersed body or object is:
Acceleration
Turbulence
Gravity
Buoyancy
Drag
For a submerged object, center of buoyancy is the same as the:
Center of mass
Center of gravity
Center of volume
Radius of rotation
All of these are correct
The concept that explains how a spinning baseball changes direction is called:
Pedro's theory
Radius of gyration
Angular impulse
The Bourne identity
The Magnus effect
Which shape is most conducive to optimizing lift?
Foil
Oblong
Rectangle
Sphere
Square
Which form of drag would have the greatest effect on a swimmer performing the crawl (freestyle) stroke in a smooth ocean?
Pressure drag
Profile drag
Shark drag
Skin friction drag
Wave drag
The stitches on a baseball make it:
Travel in an unpredictable manner
Interact less with the air it moves through
Travel with lesser velocity than a smooth ball would
Travel with greater velocity than a smooth ball would
Dynamic force due to an object or body's motion in a fluid is resolved into:
Friction and drag forces
Drag and lift forces
Buoyant and friction forces
Gravity and drag forces
An object with a specific gravity greater than 1.0 that is immersed in water will:
Have an increased drag force
Float
Sink
Spin on the surface of the water
Relative velocity is:
The fluid's absolute velocity only.
The difference between the object's absolute velocity and the fluid's absolute velocity.
The object's absolute velocity only.
Is unaffected by the shape of the object or the properties of the fluid.
