Using the turbine model you can lift anything heavy by:
a. Changing the number of blades
b. Changing the angle of the blades
c. Changing the shape or the area of the blades.
The blades are the most important part of the turbine as it changes specific form of energy to Mechanical Energy.
Through this model, you can vary ways on how to be able to lift anything heavy like the paper clips. Investigate on the how you can orient the blades to be able to know the maximum number of objects lifted.
- rotating the straw by hand or by other means (like blowing on the blades)
- dropping sand or grain on the blades
- dripping water on the blades
