What occurs due to the clockwise rotation of rotor blades generating lift in a helicopter?

• A. Pitch
• B. Torque
• C. Lift differential
• D. Yawing

Answer: (B)

The generation of torque is a result of the clockwise rotation of rotor blades in a helicopter. When the rotor blades spin, they create lift due to their design and angle of attack; however, this action also produces an equal and opposite reaction in the form of torque that causes the helicopter's body to want to rotate in the opposite direction of the rotor blades. This is a fundamental principle in aerodynamics and mechanics known as Newton's third law, where every action has an equal and opposite reaction. In practical terms, helicopter pilots must manage this torque effect through the use of a tail rotor or other control mechanisms to maintain stable flight and prevent unwanted yawing, which is the rotation of the aircraft around its vertical axis. Understanding how torque influences helicopter dynamics is essential for effective operation and control of the aircraft.
