Which force is responsible for holding a car in a frictionless banked curve?
The Horizontal Component of the normal force.
Why doesnt a train tip over when on curves?
1. The track is banked to allow for this tendency. Just like the race track for the Idi-500 is banked. 2. There is a speed limit set for the curve.
Why the marginal cost curve always cut the average cost curve at its lowest point?
This is because if a marginal figure is less than an average figure, the new average figure will decrease.

Why do road curves elevated from the outer part?
so that you have both a positive camber to assit turning and also to aid water drainage A road is "banked" (that's the term for the side-to-side sloping that you are talking about) so that, from the perspective of a car traveling along the road, the angle of the curve is lessened, making it easier for a driver to negotiate the curve. To understand this better, take the following extreme example of banking. Imagine that a road is banked a full 90 degrees, or completely vertical, in a curve. Then imagine that you are driving along this road. Of course, if the road is banked 90 degrees, or anywhere close to it, your car will fall off, so we are suspending the law of gravity for this example. As you enter this curve, and the road banks a full 90 degrees, you will find that, from your perspective as the driver of the car, the road does not curve at all, though it does climb a steep hill. At a full 90 degrees, you do not have to turn your steering wheel at all to keep your car on the road. Again, that is an extreme example. Roads are not banked anywhere near that much in real life. In fact, except on NASCAR tracks, I doubt any roads are banked more than 10-12 degrees. But you can imagine that, if a full 90 degree banking results in no curve at all (from the perspective of the car), then any banking at all will result in a lessening of the angle of the curve, from the perspective of the car.
A plane curve with each point on the curve equidistant fom fixed point at the center of figure?
A circle.You don't even need the words " ... at the center of the figure".
Why racing driver actually speed up when traversing a curve?
Driver increases the speed because racing tracks are banked by a certain angle which provides centripetal force to pass the curve in minimum time. It also act counter to centrifugal force.
A figure that has no endpoints is called a?
Closed curve, such as a circle, ellipse.
Is circumference the distance around a figure?
yes but the figure is a closed curve. The distance around an object is the perimeter.
A six letter word for a plane curve with each point on the curve being and equal distance from a fixed point at the center of the figure?
The distance from the fixed point at the center of a circle to any point on the curve is called the radius.
Does a simple curve cross over itself?
No.A path C is simple if it doesn't cross itself. A circle is a simple curve while a figure 8 type curve is not simple. (http://tutorial.math.lamar.edu/Classes/CalcIII/FundThmLineIntegrals.aspx)
How do you use fractal in a sentence?
A fractal is a geometric curve or figure such that each part of it has the same statistical character as the whole. An alternative definition is a curve which appears the same at any level of magnification.
What is happening when a production possibility curve shifts to the left?
In economics when the product possibility curve moves left it shows in decrease in production possibility. Why? try to figure it out, it helps in understanding. Peace out.
How can I create a discrete function that generates a curve over n iterations that whose sum ( the aria under the curve if it was continuous ) is constant?
There is no way to use an evolutionary algorithm or some other software to figure out a curve with a specified aria under the curve? Note that the curve starts at some value between 1000 and 2000 and ends at zero so it would be like manipulating the shape of a soap bubble. (Answers.com didn't let me include that level of detail in my question - it kept giving me errors). If physicists can figure that out, why can't we figure out how to do it with a function?
What kind of polygon is a cube?
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
A highway curve of radius is banked at angle Coefficient of F static between the road surface and the tires of sports car is mu s constant speed of the sports car round the curve for min tire wear?
Nope. It's to help the centripetal force so you won't swirl out. It's in the physics of the thing. . . . Don't quite completely understand it myself.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.
Why are the roads banked?
Newton stated that a body will continue in a straight line unless acted on by an external force. To go round a corner, the wheels are turned, and the friction of the tyres provides a centripetal force which persuades the car to abandon its straight line and go round the corner. This happens whether the road is banked or not. However, this force on the tyre does not act through the centre of mass of the vehicle. In physical terms, this is a rotational force as far as the car is concerned, and the practical effect is that the car tends to lean outward in the turn, to the extent that the inner tyres may leave the road. If the road is banked in the curve, the effect of gravity tends to make the car rotate into the centre of the curve, opposing the outward rotation. This makes the car feel more stable, as there is less outward rotational tendency. (This is why motorcyclists have to lean over in curves.)
Geometry figure that begins and ends at the same point?
A closed curve. This includes shapes made of straight-line segments.
What figure do you get if you join two points in cartesian plane?
You get a curve. If you join them along the shortest [Euclidean] distance between them, you get a straight line.
Define pappus theorems?
theorems relating respectively to the volume and the surface area of a solid generated by the revolution of plane figure around an axis lying in the same plane. 1. when a plane figure is revolved about an axis lying in the same plane (but not cutting the area)The volume generated is equal to the product of the area and the length of the path described by the centre of gravity of the area . 2. When a plane curve is revolved about an axis lying in the same plane (but not cutting the curve) the surface area generated is equal to the product of the length of the curve and the length of the path of the centre of gravity of the curve.
What does the French word 'devers' mean?
The word 'dévers' is a masculine singular noun. It means banking, be it of rails or of roads. A relevant warning sign to the motorist is 'virage en dévers', which means a dangerous 'banked curve' up ahead.
