How trains wheels stay on track?
The wheels have flanges on the inside edges, they keep the wheels on the rail. The wheels would not stay on the tracks without the flanges.
What would be the problem if railway tracks are not parallel lines?
If the tracks are not parallel, the wheels will not stay on the tracks; train wheels are spaced at a fixed width, or gauge, and that width cannot expand or contract to accommodate non-parallel tracks. Thus, if the tracks were non-parallel, the wheel would come off the track and cause a derailment.
Do wheels with caterpiller tracks run faster or do wheels with tires run faster?
On level terrain (such as a paved road) wheels with tires would be faster; on uneven terrain caterpiller tracks are faster. That assumes equal horsepower in either case.
Where can you buy cheap hot wheels tracks?
Mattel toys are sold in Toys'R'Us. But also different other retailer do have Mattel hot wheels tracks. In my opinion the cheapest way would be using eBay.
What would be a good, cheap 'starter' computer for a child in elementary school?
A compukidz teach and talk laptop would be a good starter computer for a child.
Does a train in motion contact its tracks?
Yes, train wheels remain in contact with the track at all times. The tracks support the weight of the train. They also guide the train. The wheels are shaped such that the train remains balanced on them. Any slight movement of the wheels sideways is automatically corrected so that the wheels remains exactly on the middle of the rails. If the wheels were not in contact with the track, the train would be flying.
Are wheels necessary for a bike?
Yes; pretty much. In theory, you could build a tracked bicycle. However, it might not qualify as a bicycle anymore; there would probably still be wheels keeping the tracks tight.
Why do cars stall on railroad tracks?
What I have heard is that the train wheels on the tracks both being metal cause a magnetic pull. This will stall out a slow moving vehicle, or rather a vechile that's engine is turning at a low RPM. If your theory were correct you would see this scientific event happening all the time. The truth behind this issue is there once was a time when vehicles had their starters positioned low enough that as a train approached, the magnetic field induced from its movement along the tracks created a strong magnetic field, powerful enough to effect the starter of a vehicle that passed through it, effectively stalling the motor. This problem was of course corrected by repositioning of the starter.
What is the reason battle tanks have caterpillar tracks instead of tyres?
Battle tanks use tracks to spread their weight on soft ground. Tanks weigh 40+ tons; If they used wheels they would often get stuck. It's the same reason earth moving equipment (bulldozers) use tracks.
Why wheels of a battle tank move on a belt?
The belts are called tracks. Normal vehicles, with just wheels, tend to sink easily into the mud when off a paved road, and become stuck. All the weight of the vehicle is pressed into the ground at four relatively small areas, making those areas likely to be pushed deeply into mud by the weight of the vehicle. Even before WWI inventors had realized that spreading the vehicles weight with the use of tracks instead of wheels would keep the vehicle from becoming mired in the mud. These were called caterpillar tracks. In WWI this innovation was adopted for a new use, when battle tanks were invented. The wider the track, the better the vehicle is able to keep from sinking into the mud, but this was not really understood until WWII. The tracks use the same principle as snowshoes, developed by Eskimos, that look a little bit like tennis rackets. The snowshoes spread the weight of the foot over the top of the snow, keeping the foot from sinking into the snow. Most of the wheels on the side of a battle tank are there just to give support and shape to the tracks. These are called bogey wheels. Only the back wheels on either side are connected to the engine and supply power to the tracks. These back, drive wheels are cog wheels, geared, with teeth. These teeth fit into slots on the inside of the track to drive the tracks around.
Why was the caterpillar tractor necessary?
The caterpillar tracks spread the weight of the machine over a large area - useful in wet or boggy ground (especially building sites !) Ordinary wheels concentrate the vehicles weight on a small area of tyre, which would make the vehicle sink in soft ground. Also - the tracks, as opposed to wheels provide better traction - enabling the tractor to pull more weight.
Will it be suitable to buy smart wheels train station playset for 3 1/2 years young kid?
The Smart Wheels Train Station Playset would be very good for kids around the ages of 2-5. I have personally bought it for my own child and it works perfectly. So yes, it would be good for your child.
