The back rotor of the helicopter counters the force applied to the body of the helicopter by the main rotor by applying thrust in the same direction as the main rotor. The force from the main rotor is applied in the opposite direction the main rotor is spinning. So say the force the main rotor was exerting on the body of the helicopter was causing the tail to move left then the back rotor would be designed to apply an equal force pushing the tail right to keep it from spinning.
If the back rotor of a helicopter malfunctioned it would begin to spin.

How would you Used spin in a sentence?
The circus juggler can spin eight plates at a time.
Do helicopters defy gravity?
Helicopters do not defy gravity. They generate lift through their rotating blades, which pushes against the force of gravity to keep them airborne. Without this lift, helicopters would fall to the ground like any other object under the influence of gravity.
How do helicopters show thrust?
Helicopters are notorious for showing downward thrust, prior to lifting off the ground, in a cloud of dust, flattened grass, or in people clutching their hats as they go to or from the helicopter.
Why doesnt a helicopter Spin out of control?
Most helicopters have a tail rotor for stability while others (often Russian military helicopters) have two main rotors. In both cases the two rotors spin in opposite directions, in order to cancel out any torque effect of a single rotor.
What film is this quote from Do you ever put your arms out and just spin and spin and spin?
The quote "Do you ever put your arms out and just spin and spin and spin?" is from the film "Eternal Sunshine of the Spotless Mind." It is spoken by the character Clementine, portrayed by Kate Winslet.

How do hyenas defend themselves?
I dont think they have any immediate predators and they defend themselves by living in packs. THey usually scavenge and dont really hunt. They eat meat.WRONG
Why do helicopters have a small rotor of their tail?
That is to stabilise the inherent spin of the main rotor and to steer the machine.

Why do zebras have circles?
zebras dont have circles! they have a stripe pattern
How helicopter work?
My understanding of how helicopters work is that they (suck) the air from above the blades and (blow) it down wards to create lift. the rear blades counter the spin of the top blades of it wasn't for them the helicopter would just spin round in circles (fun but not recommended) :-)
