Are train wheels magnetic?
The wheels on a train are not magnetic. They are steel wheels and the use of steel helps to reduce friction and propel the train forward.
Why maglev train is faster than ordinary train?
Because there's no friction between the train and the track. In an 'ordinary' train, friction between the wheels and the rails takes a lot of energy to overcome before the train starts moving. In a Maglev train, the train itself actually 'floats' above the track on a 'cushion' of magnetic foirce. With no friction to slow it down, the train is capable of much higher speeds.
Why does it take longer for a train to slow down than an automobile?
A train, especially a freight train, is a massively heavy vehicle. The difference between stopping a car and a train could be compared to the difference between stopping a rolling golf ball and a rolling boulder. Each set of wheels on a train has it's own brakes, but still, because of the mass of the train, it takes considerably longer to slow a train down. Also, there is less friction on train wheels and track than there is between tire treads and roads. If all the wheels of a train were suddenly stopped and locked, the train would still skid for a very considerable distance on the steel wheels and track, ruining both. == ==
Why do the wheels squeal on a train when going through a curve?
Centrifugal force is pulling the train's metal wheels against the sides of the metal train tracks, creating friction. Metal on metal makes a horrible noise.
Are train tracks metal?
Yes. Train tracks are metal because if they were wooden such fast moving train wheels will cause friction on the wooden tracks, setting them on fire.
Why do train run on tracks?
because the wheels connect to the track to keep the train stable and to give it more power.
Can friction produced by wheels of moving train generate electricity?
yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....
The differences between a car and train?
a car has 4 wheels and the train carrys 100 people or more
Do a train's wheels produce heat when they're rolling?
most likely yes, as friction can come into play, as well as the fact that the motor spining the wheels would heat and pass it on through the metal (as is an conductor).
When operating a model train does it have friction?
Yes an operating model train has friction.
Where do you find friction in a car?
There is a lot of friction associated with vehicles. A biggie is friction with air, to which the term drag is applied. There is friction in all the moving parts in the power train through the engine, the transmission and the differential. That friction also extends out the axles to the wheels, and it is particularly evident where the rubber meets the road. That covers most of it.
What is the different between bus and train?
well a bus has wheels that run on the road and the train runs on a track twice the speed.
