If you reverse polarity on the battery and the fuses are fine and the alternator check out ok why would an 81 Toyota pick-up wont stay on whithout having your foot on the gas pedal?

When the truck is idling at low RPM, the charge supplied by alternator is not sufficient to run truck and charge battery of reverse polarity. Alternator expends majority of amperage toward charging (which never takes) and increase in RPM is required to spin alternator fast enough to accomodate ignition system and charging system in unison.

When you throw an object why it rotates about its own axis?

IF you give it a spin when you throw it, then it continues to spin, because there is no torque acting on itto stop the spin.


Is your alternator broken when the pulley is frozen?

if it doesn't spin at all, yes it is broken if it doesn't spin at all, yes it is broken


What causes a low grinding sound near the Alternator when turning the Van off?

The bearings on the alternator could be going bad. Remove the belt from the alternator then spin the alternator by hand to listen for grinding.


In what sense dc motor is better than ac motor?

DC motors can spin at a much faster speed and have higher starting torque.


What is the significance of torque in a car?

It's the wheel-spin the car's axle has


What is the cause that when you turn the wheel there is a squeaking noise?

The problem is most likely a loose belt, this will happen when steering piston and pump is under a load as in turning. More torque is required to spin pulley.


Is the super spin attack required to beat Ocarina of time?

no it is not required


What is the function of anti-torque rotor of a helicopter?

To counteract the force of torque created by the main rotor. If not for that tail rotor, the torque would cause the helicopter to spin continuously around.


A four wheel drive of weight 25 kg with 500 RPM should have torque?

How much torque? I don't know. Should it have torque? Always. I have a motor that can spin close to 10'000 RPM, but I can stop it with my finger because it has very low torque. A good way to remember this is, the faster it spins, the lower the torque. You can increase the torque by using a gear chain to gear-up, trading RPM for torque. Gearing Down is the reverse.


What does the torque do to the rotor?

It rotates the rotor. Torque is produced by the magnetic force on the current induced in the squirrel cage. This magnetic force acts as torque on the rotor as a tangential force that makes it spin.


Why does the alternator spin independently after the motor is shut off?

Your belt going to the alternator is probably very loose and the motion of the turning alternator is continuing after you turn off the vehicle. Get the belt tightened right away.
