Why test tracks are banked parabolic why not elliptical or circular or hyperbolic? what are advantages of parabolic curve over another curves?
Thanx Mike..i agree with ur point as varying angle with the curve will help to counteract the centrifugal forces which vary with changing speeds.. but why specifically parabola why not ellipse or hyperbola, what will be in case of ellipse or hyperbola.. i need some geometrical reason to support why we choose this curve.Ranger Mike said:The key word here is TEST...automobile manufactures must test the vehicle over a number of different operating conditions. One symetrical oval would not tell much about the handling of the vehicle. Many different turns with differing radius and banking, short straights long straights all add to real world operating conditions. Just about all the test tracks have road course as well, and changing elevation to evaluate brakes on differing grade or slopes..
thank you mike. yeah i might be wrong ! and always get confuse between two but can you refer some book or reading material which will give m a more broad idea about same and i am very specifically talking about banking.. it would be great if u provide any study material for designing track if u know one.Ranger Mike said:the curves are not symmetrical and have various diminishing radius to replicate the off ramp of many highway exits. Nor are they constant. And you are incorrect thinking centrifugal..the proper term is centripetal force
never mind , thanks 4 ur warm wishesRanger Mike said:good luck with that
A banked parabolic curve is a type of curve often used in racetracks or test tracks. It is a curved section of the track that is higher on the outside edge and gradually slopes down towards the inside edge.
There are several benefits to using a banked parabolic curve in a test track. It allows for higher speeds and tighter turns without losing control, which is important for testing the capabilities of a vehicle. It also reduces stress on the vehicle and increases safety for drivers.
A banked parabolic curve outperforms a regular curve in terms of performance. The banking of the curve allows for greater stability and control, which means vehicles can maintain higher speeds and make sharper turns without losing traction.
One potential drawback is that the construction and maintenance of a banked parabolic curve can be more expensive and complex compared to a regular curve. It also requires more space, so it may not be feasible for smaller test tracks.
No, banked parabolic curves can also be found in roller coasters and other amusement park rides. They are also used in some railway tracks to allow trains to maintain higher speeds while making turns.
