What else can I help you with?
Why doesn't the body of the helicopter rotate in the opposite direction as A helicopter flies off its propeller rotating?
The tail propeller keeps the helicopter straight.
Why is there a fantail in a helicopter?
For the helicopter body to be in balance and direction to steer the helicopter.
How does a helicopters rotor blades make the helicopter turn left and right?
By adjusting the speed of tail rotor, which points to the side, the pilot can turn the helicopter in flight. The main upper rotor actually plays only a minor part in making helicopter turn. The part supplying most of the control is the tail rotor. Because the main rotor is spinning in one direction, without a tail rotor, the body of the helicopter would spin around in circles in the opposite direction. The reason for this is explained in the first part of Newton's third law of motion: for every action there is an equal and opposite action. The torque generated to make the rotor turn also exerts torque on the body of the helicopter "willing" it to spin the opposite direction. However, the tail rotor spins, pushing air to the side. This creates force in the opposite direction, keeping the helicopter stable. By simply adjusting the speed of the tail rotor, the helicopter can be turned in flight.
For a helicopter to be stable as it flies it must have at least two propellers. why?
Helicopters require at least two propellers to achieve stability through a concept known as "counter-torque". The main rotor produces torque that would rotate the body of the helicopter in the opposite direction. The tail rotor or fenestron is used to counteract this torque, providing stability by keeping the helicopter from spinning uncontrollably.
What is the Direction of friction for a rolling body?
The direction of friction of a rolling body is in opposite direction to the motion of the rolling body.
Why does a helicopter fly?
The rotor, shaped like an aeroplane wing, creates lift in the same way. The problem is in maintaining stability, as it will cause the body of the helicopter to rotate, too. That is why most helicopters have a tail rotor, to counter that effect and grant the pilot stability.
Some helicopters have on rotor on a horizontal axis perpendicular to the helicopter body at the tail Why is a single rotor never used?
because the spinning motion of the main rotor crates a force called torque, with makes the helicopter's body want to spin in the opposite direction. The tail rotor is used to create anti-torque and stop the body from spinning. In the cockpit, the pilot will use anti-torque pedals which change the angle that the tail-rotor's are spinning at. Allowing the body to spin slightly means it can change direction, and forcing it to spin more in the opposite direction allows it to turn (or yaw) the other way. A single rotor helicopter will spin uncontrollably in the air and will possibly not take off at all.
What is the difference between prograde rotation retrograde rotation?
Retrograde motion is the opposite of prograde motion.So, retrograde motion is where a body is moving in the direction opposite to the movement of something else. Not to be confused with apparent retrograde motion. [See related link]If you were on a child's roundabout and your friend was running alongside in the same direction you were spinning, that would be prograde. If however, your friend turned around and ran the opposite way, that would be retrograde motion. [See related link for a pictorial]In astronomy:The Earth and four other planets rotate in the same direction as the Sun does; Prograde.Venus and Uranus rotate in the opposite direction; retrograde.Do not confuse this with retrograde revolution, as no planet revolves in the opposite direction to the Sun.See related link for a full explanation.
The acceleration of a body is opposite in direction to its velocity?
If that happens, the body's speed will decrease.
What direction does the force of friction act when a body slides?
In the direction opposite to that of the sliding body.
A planet that appears to spin counterclockwise when viewed from its north pole has a?
This is the definition of prograde rotation. In the solar system, a rotating body seen from its North Pole will appear to be spinning counterclockwise. This is different then retrograde rotation in which a body spins in the opposite direction.
What is a backflip?
A backflip is a rotation of one's body in the opposite direction to the direction a person is facing.
