Across
- 3. For every action, there is an equal & opposite reaction.
- 5. The rotating section is comprised of blades projecting from a hub.
- 9. “teardrop” shaped cross-section of wind turbine blades.
- 11. The aerodynamic force that allows airplanes to fly.
- 13. A force times a distance that causes rotation.
- 14. A push or pull.
- 15. This tells us that faster-moving air has lower pressure.
- 18. Central component connecting the blades to the driveshaft
- 19. Reduces drag at blade tips to increase performance.
- 20. The electrical pressure or potential difference that drives the electric current.
Down
- 1. An electronic instrument that can measure voltage, current, and resistance.
- 2. The conversion of energy from one form to another.
- 4. The friction of the blades against air molecules as they rotate.
- 6. 1 volt = 1 amps × 1 ohm = 1 watts / 1 amps
- 7. A force that resists the relative motion of two bodies in contact.
- 8. The angle of the blades with respect to the plane of rotation.
- 10. solidity Measurement of how “solid” the rotor is.
- 12. A measure of the rate of flow of electrical charges.
- 16. The rate at which energy changes form from one form to another, or the rate at which work is done
- 17. the metric unit of power
