Homework Statement
If the force pushing the helicopter blades from the pivot point surely r is 0... therefore T (torque) is 0 also...
Homework Equations
r is the Length from pivot point to force
F is force
τ= r × F ×sin(θ)
If the force pushing the helicopter blades from the pivot point surely r is 0... therefore T (torque) is 0 also...
tiny-tim said:hi 06mangro! welcome to pf! ah, but the force actually comes from the outside of a shaft …
so r is the radius of that shaft
06mangro said:one more thing...
so does that mean the blades do not create torque...
only the shaft does?
Torque on a helicopter is the force that causes the helicopter to rotate around its axis. It is created by the rotation of the helicopter's main rotor blades and is counteracted by the tail rotor to keep the helicopter stable.
Torque can affect a helicopter's flight by causing it to rotate in the opposite direction of the main rotor's rotation. This can affect the helicopter's stability and require constant adjustments from the pilot to maintain control.
Torque is controlled on a helicopter through the use of a tail rotor. The tail rotor produces a force in the opposite direction of the main rotor's rotation, which helps to counteract the torque and keep the helicopter stable.
Some factors that can affect torque on a helicopter include the weight distribution of the aircraft, the size and speed of the main rotor, and external forces such as wind.
Helicopter pilots compensate for torque by using the helicopter's controls to adjust the tail rotor's angle and power. They may also use other techniques such as tilting the main rotor blades or adjusting the collective pitch to help counteract the torque.
