Total questions: 10
Worksheet time: 5mins
What gives turbine blades the most torque?
Length of the blades
Width of the blades
Angle of the blades
Surface area of the blades
Drag refers to...
The air resistance against the blades
The lift power of the blades
The person in your group that does nothing
The rotational force of the blades
Airfoil design provides which type of force?
Torque
Lift
Air Resistance
Drag
Airfoil design provides lift because it creates...
a new way of thinking about green energy
drag which is helpful
higher air pressure below the blade and low pressure above
helps us understand the dynamics of engineering
Which of the following is NOT a variable (change) that we might test?
Wind speed of the fan
Angle of the blades
Size of the blades
Shape of the blades
Blades that have a larger surface area will have a larger...
torque force
surface force
lift force
drag force
One way to reduce drag and increase torque would be to...
make blades out of steel
taper the blades
increase the number of blades
make gigantic blades
Which of the following is NOT a need of our turbine project?
create the fastest blade in the class
produce 20 mW of power
create well constructed, identical, sturdy blades
design is based on research
This quote from the research BEST DESCRIBES what variable?
“They are wider near the hub to improve torque and to help start the rotation. They get narrower near the tip to reduce noise and wind resistance.”
