Final answer:
The factors that affect the lift produced by spinning rotor blades are blade length, blade angle, and rotational speed.
Step-by-step explanation:
The factors that affect the lift produced by spinning rotor blades are:
- Blade length: Longer blades can generate more lift as they cover a larger area and can push against more air molecules.
- Blade angle: Adjusting the angle of the blades, known as pitch, can affect the lift. Increasing the blade's angle of attack can increase lift.
- Rotational speed: Faster rotation of the blades can generate more lift by creating more air pressure difference.
