What is tail spin?
They do not always "crash" in this manner. although when they do, it is mainly due the instabilization of the tail prop. ============================================================ if the tail prop is not spining the rotation of the main rotor will force the helicopter to spin in the opposite direction, by air drag, the tail counterbalances this force.
Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.
Because without a tail rotor the body of the helicopter would spin the opposite way of the main rotor so the tail rotor is perpendicular to prevent that : Way it works is the tail rotor spins at the same speed as the main rotor to over power the body's need to spin by giving just the right amount of need to go the other way : Hope I Helped , jd703
If a board has low spin weight, it means its lightweight, especially at the ends, making it easier to perform spins: 180's, 360's, 720's, etc. The less the board weighs, the easier it is to spin. However, in order not to compromise performance of the board between the feet (stability, width, stiffness, pop) manufacturers often remove weight from the tip and tail to reduce spin weight, thus resulting in blunted tips and tails (not rounded…
On nintendogs when you try to teach your dog spin it gets annoyed with you what are you doing wrong?
Thistactic will work for and of the nintendog games, 1)Ok, first get your dogs attention and grab its tail. 2)Second start to spin it, and your dog will spin. 3)Third click the light bulb and say spin, but if it gets spin and sit and shake mixed up keep your favorite one the same and say different ones like: paw (shake), twirl (spin), and down (sit).
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…
When helicopters main rotors are turning, it is the natural reaction of the fuselage of the helicopter to spin the other way, this is known as torque, a tail rotor spinning counteracts this force by pushing the other way, The rotor pedals change the pitch of the blades on the tail rotor, if the pilot wants to spin left, he compresses the left anti-torque (yaw) pedal, and the blades will alter their pitch to offer…
Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.
Depends whether you're on offense or defense, if you're the pitcher, spin helps you tail and cut the ball (move to left or right) and sink and rise (down and up motion.) If your in the field the spin put on the ball off the bat can make it have the same motions and cause irregular hops when the ball hits the ground.
